Description

Technical Field

[0001] The present invention relates to a crushing plant for working inert material with variable overall dimensions. Specifically, the crushing plant is adapted to crush, sieve and eject the inert material. In detail, the crushing plant is transformable and controllable to vary its overall dimensions within the space. For example, the crushing plant is of the type distributed by the company RIMAC TECHNOLOGY SA under the name MOBY 535 TRANSFORMER, MOBY 645 TRANSFORMER, MOBY 850 TRANSFORMER, MOBY 960 TRANSFORMER, MOBY 1160 TRANSFORMER, MOBY 1265 TRANSFORMER, MOBY 1180 TRANSFORMER or MOBY 1380 TRANSFORMER.Background Art

[0002] Crushing plants are known in the state of the art. Particularly, inert material crushing plants are mainly divisible into two categories of plants: mobile plants and stationary plants.

[0003] The known mobile crushing plants comprise a frame and transport means connected to the frame and defining a resting portion of the plant to the ground. The transport means are known per se and may comprise a set of tracks or tires to move the plant. The mobile crushing plants are therefore able to move independently, such as from a transport device to the working site.

[0004] On the other hand, the known stationary crushing plants do not comprise transport means and the resting portion to the ground is stationary and does not allow the movement thereof. Stationary crushing plants can only be moved and positioned at the working site by means of an external transport device and not independently.

[0005] Known plants comprise at least one material loading unit, generally a hopper, and one crushing unit coupled together and attached to the plant frame. In detail, the hopper is placed upstream of the crushing unit along one direction of development of the plant. Examples of crushing units may be a jaw crusher, a bump crusher and a cone crusher.

[0006] More specifically, the hopper is configured to receive the material to be worked and crushed and to convey the material to be worked to the crushing unit located downstream of the loading unit.

[0007] The crushing unit is configured to receive the material to be worked from the hopper, crush the material to be worked resulting in a worked material and convey the worked material to a conveyor belt connected to the frame. Normally, the crushing unit is placed between the hopper and the conveyor belt along the direction of development of the plant.

[0008] Specifically, the conveyor belt develops between an inlet portion, adapted to receive the worked material from the crushing unit, and an evacuation portion. The conveyor belt is configured to move the worked material from the inlet portion to the evacuation portion.

[0009] In addition, the crushing plant may comprise a magnetic separator associated with the conveyor belt and configured to detect and remove the metallic elements from the flow of worked material carried by the conveyor belt during use. Furthermore, the known crushing plant comprises a driving unit associated with the different components of the plant to provide power to such components. The driving unit is attached to the frame and comprises a motor and an associated motor protection casing. Generally, the motor is a heat engine configured to operate the transport means, loading unit, crushing unit and conveyor belt.

[0010] One drawback of known crushing plants is that they are plants difficult to transport. In fact, the size of known plants can reach 12-15 meters in total length with a height exceeding 3 meters. The Applicant has ascertained that road transport of the known crushing plant is hindered by the size of the plant itself, which is not always within the limits set by local trucking regulations.Description of the Invention

[0011] The Applicant has ascertained that moving the components of the plant in a way that reduces the overall dimensions of the plant allows the plant to be transported by road more easily and quickly.

[0012] In addition, the ability to move the plant allows for increased versatility of the latter, e.g. transporting it to locations with different trucking regulations.

[0013] A further object of this description is to provide a more versatile crushing plant and capable of operating different types of driving units.

[0014] A further object of this description is to provide a more versatile crushing plant and capable of operating different types of crushing units.

[0015] A further object of this description is to provide a more versatile crushing plant and capable of moving into different types of work environments.

[0016] An additional object of this description is to provide a crushing plant that enables faster maintenance of the plant components.

[0017] A further object of the present invention is to provide a more efficient crushing plant with reduced downtime.

[0018] The aforementioned objects are achieved by the crushing plant with reduced overall dimensions according to claim 1.Brief Description of the Drawings

Conveyor belt

[0027] The crushing plant 100 comprises a conveyor belt 107 connected to the frame 102. The conveyor belt 107 mainly extends along a longitudinal direction A-A between an inlet portion 107a and an opposite evacuation portion 107b. The inlet portion 107a is adapted to receive material, especially material worked by the crushing unit 106. The evacuation portion 107b is adapted to evacuate the material from the crushing plant 100 and to convey the inert material at output. The conveyor belt 107 is configured to move the inert material from the inlet portion 107a to the evacuation portion 107b.

[0028] According to one aspect, the conveyor belt 107 is switchable between an elongation configuration and a folded configuration. In particular, the conveyor belt 107 comprises sections 114, 115 connected to each other in a rotatable manner, e.g., by means of pivoting elements. For example, the sections 114, 115 are connected by means of pins defining a respective axis of rotation around which at least one of the sections is rotatable. In more detail, in the elongation configuration, the sections 114, 115 are arranged substantially aligned along a straight longitudinal direction, as e.g. shown in Figure 2. In the folded configuration, the sections 114, 115 are close to each other, thus reducing a lateral extension of the conveyor belt 107 with respect to the frame 102, as e.g. shown in Figure 1. In other words, the overall dimensions of the conveyor belt 107 laterally to the frame 102, along the direction of development, is reduced when passing from the elongation configuration to the folded configuration to facilitate the movement of the crushing plant 100.

[0029] In one embodiment, the loading unit 104, the crushing unit 106 and the conveyor belt 107 are placed along the direction of development B-B of the plant 1.

In other words, the driving unit 110 is configured to drive the operation of the loading unit, of the crushing unit, of the conveyor belt and of the transport means.Magnetic separator

[0032] In one embodiment, the crushing plant 100 comprises a separator 108 associated with the conveyor belt and connected to the frame 102. Specifically, the separator 108 is arranged along the main direction of development B-B of the plant 100 downstream of the crushing unit 106. The separator 108 is configured to detect and remove unwanted materials from the worked material. For example, the separator 108 is of the type of a magnetic separator and is suitable for the identification, detection and removal of the metallic material from the worked material.

[0033] In detail, the separator 108 is positioned in the proximity of the conveyor belt 107 so as to analyze the worked material as it is transported from the inlet portion 107a to the evacuation portion 107b of the conveyor belt. More specifically, the separator 108 is positioned facing a transport surface 107c of the conveyor belt 107. The separator 108 can be at a predefined minimum distance from the transport surface, wherein the minimum distance is selected so as to optimize the process of detecting and removing unwanted material from the flow of worked material.Spraying system

[0034] According to one aspect, the crushing plant 100 comprises a spraying system 109 associated with the loading unit 104. The spraying system 109 is connected to the loading unit 104, particularly to the hopper 105, or to the crushing unit 106 and is configured to reduce the volatility of a volatile component of the material to be worked.

[0042] Specifically, the crushing plant 100 of the present invention has variable overall dimensions.

[0043] The frame 102 develops along a direction of development B-B, particularly between a front portion 102a and a rear portion 102b.

[0044] The loading unit 104 is connected to the frame 102 and is adapted to receive inert material and to feed the inert material to a crushing unit 106. In detail, the crushing unit 106 associated with the loading unit 104 is configured to receive the inert material and to perform a working phase of the inert material and to feed the worked inert material to the conveyor belt 107.

[0045] The conveyor belt 107 is connected to the frame 102 and configured to receive and transport the worked inert material.

[0046] The crushing plant 100 with variable overall dimensions is switchable between a working configuration and a transport configuration. In the working configuration, the crushing plant 100 has a first length along the direction of development B-B. In the transport configuration, the plant 100 has a second length along the direction of development B-B. The second length is less than the first length. In other words, the plant increases its length along the direction of development by switching from the transport configuration to the working configuration. Conversely, the plant decreases its length along the direction of development by switching from the working configuration to the transport configuration. The overall dimensions of the crushing plant along the direction of development are variable as a function of the plant configuration. In the transport configuration, the plant has smaller overall dimensions along the direction of development than when the plant is in the working configuration.

[0047] In one embodiment, the crushing plant has a variable width, and thus overall dimensions, along a first direction Z-Z transverse to the direction of development B-B. The first direction Z-Z can be perpendicular to the direction of development B-B.

[0048] Specifically, the crushing plant 100 has a first width and a second width along the first direction Z-Z in the working configuration and in the transport configuration, respectively. The second width is smaller than the first width. In other words, the plant has overall dimensions along the first direction Z-Z that decrease as it passes from the working configuration to the transport configuration and, conversely, increase as it passes from the transport configuration to the working configuration.

[0049] In one embodiment, the crushing plant 100 has a variable height, and thus overall dimensions, along a second direction Y-Y transverse to the direction of development B-B. The second direction Y-Y can be perpendicular to the direction of development B-B and / or to the first direction Z-Z. The first direction Z-Z, the second direction Y-Y and the direction of development B-B can be perpendicular to each other. The direction of development B-B and / or the first direction Z-Z can be horizontal and the second direction Y-Y can be vertical. In detail, in the working configuration, the crushing plant 100 has a first height and a second height along a second direction Y-Y transverse to the direction of development B-B in the working configuration and in the transport configuration, respectively. In the working configuration, the plant has the first height along the second direction Y-Y. In the transport configuration, the crushing plant 100 has the second height along the second direction.Mobile loading unit

[0050] In one embodiment, the loading unit is movable with respect to the frame 102 from and / or to the front portion 102a of the frame 102. In particular, the loading unit 104 is connected to the frame 102 in the proximity of the rear portion 102b of the frame 102 and is movable with respect to the same rear portion 102b. In detail, the loading unit 104 is configured for the relevant movement with respect to the frame 2 when the crushing plant moves between the transport configuration and the working configuration.

[0051] Specifically, the crushing unit 106 is connected to the frame 102 downstream of the loading unit 104 along the direction of development B-B. The crushing unit 106 is associated with the loading unit 104 to receive the inert material. In detail, the crushing unit 106 is adapted to feed the worked inert material to the conveyor belt 107 connected to the frame 102 and arranged downstream of the crushing unit 106 along the direction of development B-B.

[0052] In detail, the conveyor belt 107 is connected to the frame 102 in the proximity of the front portion 102a. More specifically, the conveyor belt 107 is configured to eject the worked material from the plant. In other words, during use, the conveyor belt 107 receives the inert material from the crushing unit 106 and transports the same inert material which is ejected from the plant. In detail, the conveyor belt 107 is configured to receive the inert material at the inlet portion 107a and to transport the material to and up to the evacuation portion 107b to eject the material from the plant. The loading unit 104 of the crushing plant 100 is movable with respect to the frame 102 to and from the front portion 102a and / or to and from the rear portion 102b. In detail, the loading unit 104 is movable close to / away from the front portion 102a and close to / away from the rear portion 102b of the frame 102. The loading unit 104 can be moved with respect to the frame 102 along or parallel to the direction of development B-B. In more detail, the movement of the loading unit 104 with respect to the frame 102 comprises a component parallel to the direction of development B-B, preferably a horizontal component. The loading unit 104 can be moved horizontally to and from the front portion and / or the rear portion. In detail, the movement of the loading unit can be horizontal. The loading unit is configured to move with respect to the frame when the plant moves between the transport configuration and the working configuration.

[0053] According to one aspect, the crushing plant 100 also comprises a first movement system 131 associated with the frame 102 and with the loading unit 104. The first movement system 131 is configured to move the loading unit 104 with respect to the frame 102 at least from and to the front portion 102a of the frame 102 or from and to the rear portion 102b of the frame 102, especially so as to vary the height of the plant 100. In other words, the first movement system 131 is configured to move the loading unit 104 with respect to the frame 102 close to and away from the front portion 102a or the rear portion 102b of the frame 102. The first movement system 131 is configured to move the loading unit 104 horizontally. The first movement system 131 is configured to move the loading unit so as to vary the height of the crushing plant 100 between the first height and the second height.

[0054] In one embodiment, the loading unit 104 is movable away from / close to the frame 102 along a direction of movement F-F of the loading unit 104 transverse to the direction of development B-B. Specifically, the direction of movement F-F of the loading unit 104 transverse to the direction of development B-B is parallel to or coincident with the second direction Y-Y.

[0055] The first movement system 131 is configured to move the loading unit 104 with respect to the frame 102 along the direction of movement F-F of the loading unit 104 transverse to the direction of development B-B. In other words, a distance along the direction of movement F-F of the loading unit 104 between the loading unit 104 and the frame 102 is variable by moving the loading unit 104. The direction of movement F-F of the loading unit 104 can be vertical and the loading unit 104 can be configured to move vertically. For example, Figures 14 to 16 or Figures 17 to 19 show the loading unit 104 of the plant 100 at different respective heights and respective distances from the frame 102 and from the front portion 102a.

[0056] In more detail, the first movement system 131 is configured to move the loading unit 104 close to and away from the crushing unit 106 at least along or parallel to the direction of development B-B and / or along the direction of movement F-F of the loading unit 104. According to one aspect, the first movement system 131 is configured to move the loading unit both to and from the front or rear portion 102a, 102b and along the direction of movement F-F of the loading unit 104.

[0057] In particular, moving the loading unit 4 vertically allows the crushing unit to be connected to the frame so that it is farther away from the conveyor belt and / or the resting portion, and thus from the ground, than the systems of known type. Advantageously, connecting the crushing unit to the frame in a raised position by height compared with known systems makes it easier to maintain the plant and reduces the possibility of inert material damaging the plant when transferred from the loading unit to the crushing unit and from the crushing unit to the conveyor belt.

[0058] According to one aspect, the loading unit 104 is switchable among a plurality of positions comprising at least one lowered position and one raised position. For example, Figure 14 shows a crushing plant 100 with the loading unit 104 placed in the lowered position, while Figure 16 shows the same plant with the loading unit 104 placed in the raised position. In detail, the loading unit 104 is configured to pass from the lowered position to the raised position as a function of the configuration of the crushing plant 100. In detail, when the crushing plant 100 is in the working configuration, the loading unit 104 is in the raised position. When the crushing plant 100 is in the transport configuration, the loading unit 104 is in the lowered position.

[0059] In the lowered position, the loading unit 104 and the frame 102 are placed at a first distance, particularly defined along the direction of movement F-F of the loading unit 104. In detail, in the lowered position, the loading unit 104 and the crushing unit 106 are spaced apart from each other, particularly along the direction of development B-B. In the raised position, the loading unit 104 and the frame 102 are at a second distance, preferably defined along the direction of movement F-F of the loading unit 104. The second distance is greater than the first distance. In detail, in the raised position, the loading unit 104 and the crushing unit 106 are close to each other. More in detail, in the raised position, the loading unit 104 is in the proximity of the crushing unit 106 and adapted to feed the inert material to such crushing unit 106, such as e.g. shown in Figure 16 or in Figure 19.

[0060] By moving the loading unit 104 with respect to the frame 102, the overall height, and therefore the overall dimensions, of the plant can be reduced at least in the proximity of the loading unit 104. By moving the loading unit 104 from the raised position to the lowered position, the plant height can be reduced by 0.6m-1m. In other words, the second height may be smaller than the first height by 0.6 meters to 1 meter.

[0061] In one embodiment, the loading unit 104 is movable close to / away from the front and / or rear portion 102a, 102b in the movement among the plurality of positions. In more detail, when moving between the lowered position and the raised position, the loading unit 104 moves close to / away from the front portion 102a of the frame 102. When displacing from the lowered position to the raised position, the loading unit 104 moves close to the front portion 102a of the frame 102. Conversely, when displacing from the raised position to the lowered position, the loading unit 104 moves away from the front portion 102a of the frame 102. According to one aspect, the loading unit 104 is movable along the direction of movement F-F of the loading unit 104 when moving among the plurality of positions. In detail, the distance between the frame and the loading unit along the direction of movement F-F of the loading unit 104 increases in the passage from the lowered position to the raised position of the loading unit. Conversely, the distance between the frame and the loading unit along the direction of movement F-F of the loading unit 104 reduces in the passage from the raised position to the lowered position of the loading unit.

[0062] According to one aspect, the loading unit 104 is movable horizontally and vertically when moving among the plurality of positions. In particular, the loading unit 104 is configured to move vertically and horizontally when moving among the plurality of positions.

[0063] The first movement system 131 can be configured to move the loading unit 104 along a single trajectory when moving from the lowered position to the raised position and vice versa. In detail, the single trajectory of the loading unit has a vertical component and a horizontal component. More specifically, in the passage from the lowered position to the raised position and in the passage from the raised position to the lowered position, the loading unit is configured to follow the same single trajectory. In detail, the single trajectory is a linear trajectory. The trajectory can be straight.

[0064] According to one aspect, the first movement system 131 comprises a kinematic chain. In more detail, the first movement system 131 comprises a respective support 132 attached to the loading unit 104. In detail, the support 132 of the first movement system is connected to the hopper 105, preferably to a base 136 of the hopper 105. The support 132 of the first movement system is connected to the hopper 105 to be locked together with the hopper 105 when displacing the loading unit 104 among the plurality of positions.

[0065] In one embodiment, the first movement system 131 comprises a driven member 133 constrained to the frame 102 and connected to the support 132 of the first movement system. In detail, the driven member 133 is constrained to the frame 102 so as to have just one degree of freedom with respect to the frame 102. The driven member 133 is movable with respect to the frame 102 close to / away from the rear portion 102b. In detail, the driven member 133 moves close to the rear portion 102b of the frame 102 when displacing the loading unit 104 from the lowered position to the raised position. Conversely, the driven member 133 moves away from the rear portion 102b of the frame 102 when displacing the loading unit 104 from the raised position to the lowered position.

[0066] In addition, the first movement system 131 comprises an actuator 134 constrained to the driven member 133.

The first release / connecting means 125 may attach the crushing unit 106 to the frame 102, when activated.

[0081] In one embodiment, the plant 100 is also switchable between a first blocked configuration and a first free configuration. In the first blocked configuration, the crushing unit 106 is attached to the frame 102. In the first free configuration, the crushing unit 106 is movable away from and / or close to the frame 102. In other words, in the first free configuration of the crushing plant 100, the crushing unit 106 is either disconnectable from the frame 102 or disconnected from the frame 102 and movable away from such a frame 102. In the first blocked configuration of the crushing plant 1, the crushing unit 106 is constrained or attached to the frame 102 and can be blocked at least partly in contact with such a frame 102. In more detail, the first release / connecting means 125 are activated, or active, in the first blocked configuration and deactivated in the first free configuration. For example, Figure 13 shows a crushing plant 100 wherein the plant is in the first free configuration and the crushing unit 106 is disconnected and movable close to / away from the frame 102.

[0082] According to one aspect, the frame 102 extends substantially along the direction of development B-B.

[0083] For example, Figure 13 and 14 show a crushing plant in the first free configuration with the direction of movement E-E of the crushing unit 106 perpendicular to the direction of development B-B. Again, for example, Figures 15 and 16 show the plant 100 in the first blocked configuration wherein the crushing unit 106 is connected to the frame 102 and its movement along the direction of movement E-E of the crushing unit 106 is blocked.

[0084] Advantageously, moving the crushing unit 106 away from and close to the frame 102 allows the crushing unit to be disconnected from the frame 102 so that it can be moved away from the plant and, if necessary, replaced with an additional crushing unit 106. For example, if the crushing unit 106 were damaged or malfunctioning, it would be possible to disconnect the damaged crushing unit from the frame, and thus from the plant, to replace it with an additional functioning crushing unit 106 without the need to interrupt plant operation for long periods. In fact, the first release / connecting means are configured to allow the crushing unit 106 to be released and connected quickly.

In other words, when replacing or removing the crushing unit, it is possible to disconnect such a crushing unit from the hydraulic system of the plant without implementing changes or replacements to the hydraulic system of the plant. In detail, it is possible to replace a crushing unit with an additional crushing unit without replacing the hydraulic system of the plant and by coupling and using the additional crushing unit to the same hydraulic system coupled and previously used by the previous crushing unit.

[0085] In use, an overhead crane, a crane or other similar heavy-lifting equipment may be used to move the crushing unit 106 close to / away from the frame 102.

In detail, each lateral bracket 126a comprises holes adapted to couple to the first release / connecting means 125 or adapted to receive such first release / connecting means. The holes are sized to receive respective screws of the first release / connecting means 125.

[0088] In the first blocked configuration, the first release / connecting means 125 block the relevant movement of the crushing unit 106 with respect to the frame 102 at least along the direction of movement E-E of the crushing unit 106. In detail, the first release / connecting means 125 constrain the connecting portion 126 of the crushing unit 106 in contact with the frame 102. Specifically, the first release / connecting means 125 constrain each lateral bracket 126a of the crushing unit 106 in contact with the frame 102.

The main body 130 at least partly defines the cavity 128 and the inlet 128a.

[0098] In one embodiment, the main body 130 is connected to each lateral bracket 126a by means of a respective cylinder of the second movement system 127.

Specifically, when each cylinder of the second movement system is in an extension configuration, or the cylinder rod is extended with respect to the cylinder body, the crushing unit 106 is in the close position with respect to the loading unit 104. When each cylinder of the second movement system is in a close configuration, or the rod is inserted into the cylinder body, the crushing unit 106 is in the spaced position with respect to the loading unit 104. When moving the crushing unit 106 among the respective plurality of positions, the main body 130 is configured to move with respect to each lateral bracket 126a. The main body 130 is configured to rotate with respect to the lateral brackets when moving the crushing unit 106 among the plurality of positions.

[0121] Specifically, the third movement system 111 comprises pairs of rollers connected to the conveyor belt 107. The sliding elements 113 can be configured to slide in each guide of the pair of guides.

[0122] According to one aspect, the sliding elements 113 are connected to lateral portions of the conveyor belt in the proximity of the inlet portion 107a. In detail, the sliding elements 113 comprise two pairs of rollers, wherein each pair of rollers is connected to a respective lateral portion of the conveyor belt 107 and connects the belt to a respective guide of the pair of guides of the frame.

[0123] In a further embodiment, the conveyor belt 107 is switchable among a plurality of positions comprising: a compact position wherein the inlet portion 107a is at a first distance from the resting portion 103a of the crushing plant 100, and an extension position wherein the inlet portion 107a is at a second distance from the resting portion 103a.

[0124] In other words, the conveyor belt 107 has a respective compact position wherein the inlet portion 107a is in the proximity of the resting portion 103a of the crushing plant. In detail, when the belt is in the respective compact position, the inlet portion 107a is located in the proximity of an outlet of the crushing unit 106 to receive the worked and / or sieved material from the crushing unit 106. In more detail, when the belt is in the respective compact position, the inlet portion of the conveyor belt 107 is at a minimum distance from the resting portion and from the ground.

[0125] In detail, the conveyor belt 107 may be configured to be placed in the respective compact position when the plant is in the working configuration. The conveyor belt may be configured to be in the respective extension position when the crushing plant is in the transport configuration so as to facilitate the displacement and transport of the plant to the work site by moving away from the resting portion. When the plant is in the transport configuration, the conveyor belt 107 is in the respective extension position. Conversely, when the plant is in the working configuration, the conveyor belt 107 is in the compact position so that the inlet portion 107a is properly positioned to receive the inert material from the crushing unit 106.

[0126] In the position of extension, the conveyor belt 107 is moved away from the frame 102 and from the resting portion 103a of the crushing plant. In detail, in the extension position, the inlet portion 107a of the conveyor belt 107 is moved away from the outlet of the crushing unit 6.

[0127] For example, in Figure 5, the conveyor belt 107 is shown in a compact position, and in Figures 6 and 7, the conveyor belt 107 is shown in the extension position. According to one aspect, the second distance is greater than the first distance. In more detail, the inlet portion 107a is moved away from the ground as the conveyor belt moves from the compact position to the extension position. The inlet portion 107a is moved close to the ground as the conveyor belt moves from the extension position to the compact position.

[0128] According to one aspect, the first distance comprises a respective first vertical component and a respective first horizontal component, and the second distance comprises a respective second vertical component and a respective second horizontal component. In particular, the second vertical component is greater than the first vertical component.

[0129] In other words, the distance in the vertical direction between the inlet portion 107a of the conveyor belt 107 and the resting portion 103a increases in the passage from the compact position to the extension position. The height position of the conveyor belt 107 and, in particular, of the inlet portion 107a increases as the conveyor belt moves from the compact position to the extension position and decreases as the conveyor belt moves from the extension position to the compact position. The respective vertical component of the distance of the inlet portion 107a from the resting portion of the plant increases with the passage from the compact position to the extension position, and vice versa increases with the passage from the extension position to the compact position.

[0130] For example, the inlet portion 107a may have a vertical distance from the resting portion 103a or from the ground of between 20cm and 60cm when the conveyor belt 107 is in the compact position and a vertical distance from the resting portion or from the ground of between 70cm and 100cm when the conveyor belt is in the extension position.

[0131] According to one aspect, such as that shown in the figures, the conveyor belt 107 is cantilevered from the frame 102. In the passage from the compact position to the extension position, the portion of the conveyor belt cantilevered from the frame increases. In the passage from the extension position to the compact position, the portion of the conveyor belt cantilevered from the frame decreases. According to one aspect, the conveyor belt 107 comprises sections 114, 115 connected to each other in a rotatable manner. The sections 114, 115 of the conveyor belt 107 are connected to each other by means of pivoting elements. For example, the sections 14, 15 are connected to each other by means of pins defining an axis of rotation around which at least one of the sections is rotatable. Specifically, the conveyor belt 107 may have a first section 114 connected to the frame 102 and a second section 115 connected to the first section 114 by means of pins. The inlet portion 107a of the conveyor belt can be defined by the first section 114 and the evacuation portion 107b can be defined by the second section 115. The second section 115 can rotate around the axis of rotation defined by one or more connecting pins with the first section 114 of the conveyor belt 107. According to one aspect, in the working configuration of the crushing plant 100, the sections 114, 115 are arranged substantially along or parallel to the trajectory of movement X and / or along or parallel to the direction of development B-B. Still according to one aspect, in the transport configuration of the crushing plant 100, the sections 114, 115 are moved close to each other, thus reducing a lateral extension of the conveyor belt 107 with respect to the frame 102.

[0132] In one embodiment, the conveyor belt 107 is switchable between an elongation configuration and a folded configuration.

[0133] In the working configuration of the plant, the conveyor belt 107 is configured to be in the elongation configuration. In other words, in the working configuration of the plant, the sections 114, 115 are arranged substantially along or parallel to the trajectory of movement X, such as e.g. shown in Figures 2, 3 and 13 or in Figure 23. In the transport configuration of the plant, the conveyor belt 107 is configured to be in the folded configuration. In other words, in the transport configuration of the plant, the sections 114, 115 are moved close to each other, thus reducing a lateral extension of the conveyor belt 107 with respect to the frame 102, such as e.g. shown in Figure 1 and in Figures 14 to 19. In other words, the overall dimensions of the conveyor belt 107 laterally to the frame 102 is reduced in the switch from the working configuration to the transport configuration of the plant, i.e. in the switch from the elongation configuration to the folded configuration of the conveyor belt 107, to facilitate the movement of the crushing plant 100.

[0134] According to one aspect, at least one section is configured to rotate around an axis of rotation as the conveyor belt switches from the elongation configuration to the folded configuration and vice versa.

In addition, the third movement system 111 may comprise a respective additional pair of cylinders configured to move the conveyor belt 107 between the elongation configuration and the folded configuration and vice versa.

[0137] In one embodiment, the control unit is in signal communication with the third movement system 111 and configured to command the third movement system 111 to move at least partly the conveyor belt 107 along the trajectory of movement X.

[0138] In detail, the control unit is configured to command the third movement system 111 to move the conveyor belt among the plurality of positions and / or to move the conveyor belt from the elongation configuration to the folded configuration and vice versa.

[0139] In one embodiment, the control unit is configured to command the conveyor belt 107 to transport and move the worked and / or sieved material from the inlet portion 107a to the evacuation portion 107b.

[0140] According to one aspect, the conveyor belt 107 is configured to switch from the elongation configuration to the folded configuration when the plant moves from the working configuration to the transport configuration.Magnetic separator

[0141] In one embodiment, the crushing plant 100 comprises a magnetic separator 108 which is movable with respect to the frame 102 and / or to the conveyor belt 107. The magnetic separator 108 is configured for the detection and removal of magnetic material from a volume of material arranged on a transport surface 107c of the conveyor belt 107.

[0142] According to one aspect, the volume of material comprises inert material. For example, the volume of material may comprise construction and demolition materials, excavated soil and rocks, stones, sand, asphalt, gravel, steel mill slag, plastics, paper, wood, glass. In particular, the separator can be configured for the detection and removal of ferromagnetic material. For example, the ferromagnetic material may comprise iron, cobalt, nickel and metal alloys.

[0143] In detail, the magnetic separator 108 comprises a lifter 116 associable with the conveyor belt 107. The lifter 116 is adapted to attract and transport the magnetic material. Specifically, the lifter 116 is configured to remove the magnetic material from the volume of material arranged on the conveyor belt 107.

[0144] According to one aspect, the lifter 116 comprises a magnet adapted to attract magnetic material and an evacuation belt 121 arranged around the magnet. The evacuation belt 121 is configured to receive and transport the magnetic material.

[0145] In detail, the evacuation belt 121 is configured to move the magnetic material away from the conveyor belt 107.

[0146] In detail, the evacuation belt 121 may have baffles 122 projecting from an outer surface 121a of the evacuation belt 121. In more detail, the outer surface 121a is configured to receive and contact the magnetic material attracted by the magnet during use. The baffles 122 are configured to contact the magnetic material which is arranged on the outer surface of the evacuation belt and to reduce the slipping of the magnetic material along the outer surface of the evacuation belt. For example, Figure 11 shows a separator 108 comprising an evacuation belt with four baffles 122 projecting from the outer surface 121a of the evacuation belt and facing upwards.

[0147] Advantageously, the baffles 122 of the evacuation belt 121 allow the magnetic material in contact with the outer surface of the evacuation belt to be transported more effectively and prevent at least some of the magnetic material from slipping on the evacuation belt.

[0148] In detail, the lifter 116 is movable with respect to the conveyor belt 107 close to / away from the transport surface 107c. More specifically, the lifter 116 faces the conveyor belt 107. In other words, the outer surface 121a of the evacuation belt 121 faces at least partly the transport surface 107c of the conveyor belt 107. More specifically, the lifter 116 is movable between a respective close position, wherein the lifter 116 has a first distance from the conveyor belt 107, and a respective spaced position wherein the lifter 116 has a second distance greater than the first distance from the conveyor belt 107. In particular, during use, the lifter 116 is placed in the position close to the first distance from the transport surface 107c of the conveyor belt 107 to effectively detect and attract the magnetic materials. In detail, the lifter 116 in the close position is placed at a minimum distance from the transport surface 107c.

[0149] The first distance between the lifter and the conveyor belt can be defined as a function of a particle size of the volume of material arranged on the conveyor belt 107. In detail, the first distance is greater than a maximum height of the volume of material from the transport surface so that the distance between the lifter 116 and the conveyor belt 107 is enough for the movement of the volume of material in the area between the conveyor belt 107 and the lifter 116. The second distance is greater than the first distance so that the material with greater size than the first distance can be transported and moved to the area between the lifter 116 and the conveyor belt 107 thus reducing the likelihood of such material damaging the lifter 116. In addition, the lifter 116 is configured to move from the close position to the spaced position and vice versa depending on a protrusion of the material arranged on the conveyor belt 107 with respect to the first distance. In detail, the lifter 116 is configured to move from the close position to the spaced position if the height from the transport surface 107c of the material arranged on the conveyor belt 107 is greater than the first distance. In other words, if the material arranged on the conveyor belt 107 has a size equal to or greater than the first distance, the lifter 116 is configured to displace from the close position to the spaced position. Advantageously, displacing the lifter 116 from the close position to the spaced position as a function of a size of the material arranged on the conveyor belt 107 allows reducing the possibility that the material arranged on the conveyor belt 107 may impact and damage the lifter 116.

The fourth movement system 118 can be configured to move the lifter 116 from the close position to the spaced position as a function of a contact between the lifter 116 and at least one portion of the material.

[0159] The fourth movement system 118 can be configured to move the lifter 116 as a result of a contact between the material arranged on the conveyor belt 107 and the lifter 116, specifically a contact between the material arranged on the conveyor belt 107 and the outer surface 121a of the evacuation belt 121.

The second release / connecting means 141 may attach the driving unit 110 to the frame 102, when activated.

[0176] Advantageously, connecting the driving unit 110 to the frame 102 in a removable manner allows the driving unit to be removed and disconnected from the frame, and thus from the plant, when needed. For example, if the driving unit 110 were damaged or malfunctioning, it would be possible to disconnect it from the frame and replace it with a functioning driving unit. In addition, the ability to disconnect the driving unit enables maintenance of the driving unit to be made by moving it from the crushing plant, e.g. by arranging the driving unit in a workshop for maintenance.

[0177] In one embodiment, the plant 100 is switchable between a second blocked configuration and a second free configuration. In the second blocked configuration, the driving unit 110 is attached to the frame 102. In the second free configuration, the driving unit 110 is movable away from / close to the frame 102.

In the second blocked configuration of the crushing plant 100, the driving unit 110 is constrained or attached to the frame 102 and can be locked at least partly in contact with such a frame 102. In more detail, the second release / connecting means 141 are activated, or active, in the second blocked configuration and deactivated in the second free configuration. For example, Figures 30 and 31 show a crushing plant 100 in the second free configuration wherein the driving unit 110 is disconnected and movable close to / away from the frame 102.

[0178] Specifically, in the second free configuration, the driving unit 110 is movable away from / close to the frame 102 along a respective direction of movement G-G of the driving unit 110. Specifically, the direction of movement G-G of the driving unit 110 is transverse to the direction of development B-B. In the second blocked configuration, the driving unit 110 is constrained to the frame 102 in the direction of movement G-G of the driving unit 110. In other words, in the second blocked configuration, the movement of the driving unit 110 along the direction of movement G-G of the driving unit 110 is blocked by the release / connecting means 11.

[0179] In particular, the direction of movement G-G of the driving unit 110 can be perpendicular to the direction of development B-B.

[0180] For example, Figures 30 and 31 show a crushing plant in the second free configuration with the direction of movement G-G of the driving unit 110 perpendicular to the direction of development B-B. Again, for example, Figures 28 and 29 show the plant 100 in the second blocked configuration wherein the driving unit 110 is connected to the frame 102 and the movement thereof along the direction G-G of the driving unit 110 is blocked.

[0181] According to one aspect, the second release / connecting means are configured to allow the driving unit 110 to be released and connected quickly.

[0182] The crushing plant 100 is configured to release / connect the driving unit 110 from / to the frame 102 within a maximum time frame of 2 hours, preferably 1 hour, even more preferably half an hour. The second release / connecting means advantageously allow the driving unit 110 to be replaced or disconnected quickly, thus reducing the plant downtime and promoting maintenance of the plant and of the driving unit.

[0183] In use, an overhead crane, a crane or other similar heavy-lifting equipment may be used to move the driving unit 110 close to and / or away from the frame 102. Specifically, an overhead crane can move the driving unit 110 away from / close to the frame 102 vertically and / or along the direction of movement G-G of the driving unit 110.

[0184] In one embodiment, the driving unit 110 comprises a respective connecting portion 142 for the connection to the frame 102. The connecting portion 142 of the driving unit 110 is connected to the frame 102 by means of said second release / connecting means 141. In the second blocked configuration of the crushing plant, the connecting portion 142 of the driving unit 110 is attached to the frame by the second release / connecting means 141. In the second free configuration, the connecting portion 142 of the driving unit 110 is movable with respect to the frame 102 and can be moved away from the frame 102 and / or close to the frame 102.
