Description

Technical Field

[0001] This disclosure generally relates to mineral material processing. This disclosure specifically relates to, but is not limited to, mineral material crushing. This disclosure specifically relates to, but is not limited to, crusher feeding in mineral material processing. Background Technology

[0002] This section provides useful background information, but does not acknowledge that any technology described herein represents prior art.

[0003] Mineral processing sometimes carries the risk of dust and some material being dispersed into the surrounding environment; for example, rocks may fly out of the crusher feed chute. To mitigate this risk, some existing cone crusher feed chutes are surrounded by a collar wall (neck wall). This solution does not include a cover, i.e., a top (which will be required by some future regulations).

[0004] Because the annular wall increases the height of the mineral processing equipment and prevents entry into the feed chute, existing annular walls consist of two hinged parts, allowing one part to pivot on top of the other to enter the feed chute and descend with the feed conveyor to the transport position. Due to the significant weight of the annular wall, pivoting it to the maintenance and transport positions is difficult and time-consuming, even without the additional weight of the top.

[0005] The inventors have discovered a method by which a foldable feed trough cover with walls and a top can be easily and safely operated, i.e., pivoted to different positions. Summary of the Invention

[0006] The scope of protection claimed by the various embodiments of this disclosure is defined by the independent claims.

Attached Figure Description

[0021] Some exemplary embodiments will be described with reference to the accompanying drawings, in which: Figure 1 A side view schematically showing the crusher feed chute cover in a first position according to an example embodiment is shown. Figure 2 A side view schematically showing the crusher feed chute cover in a second position according to an example embodiment is shown. Figure 3 A side view schematically showing the crusher feed chute cover in a third position according to an example embodiment is shown. Figure 4 A side view schematically illustrates a crusher feed chute cover in a fourth position according to an example embodiment; and Figure 5 A side view of a mineral material processing apparatus according to an example embodiment is shown schematically. Detailed Implementation

[0022] In the following description, similar reference numerals denote similar elements or steps.

[0023] Figure 1 A side view schematically illustrates a crusher feed chute cover in a first position according to an example embodiment. Figure 1 The first position shown is the operating position, i.e., the position where the crusher feed chute cover is closed and covers the feed chute of the crusher 100. In an example embodiment, the crusher includes a cone crusher or a rotary crusher. Figure 1 Also shown is a feed conveyor 50 configured to feed mineral material into the feed chute of a crusher.

[0024] The feed chute cover includes a first component 10 and a second component 20. In a first position, the first component 10 and the second component 20 together cover the feed chute of the crusher 100 by forming walls 10b, 20b and tops 10a, 20a. In an example embodiment, the top component 10a is a removable component of the first component 10, and the top component 20a is a removable component of the second component 20, and can be removed when not needed (e.g., when direct feeding from above is required).

[0025] In one example embodiment, the shape of the feed trough cover substantially corresponds to the shape of the feed trough. In one example embodiment, the wall 10 has a circular or cylindrical shape surrounding the feed trough. In one example embodiment, the first component 10 and / or the second component 20 of the feed trough cover are made of a metal sheet (including metals such as steel). In another example embodiment, the first component 10 and / or the second component 20 of the feed trough cover are made of a material other than metal. In yet another example embodiment, the first component 10 and the second component 20 comprise materials different from each other. In yet another example embodiment, the top component 10a and / or the top component 20a comprise materials different from each other and / or different from the materials of the first wall component 10b and / or the second wall component 20b.

[0026] The first component 10 and the second component 20 of the feed chute cover are attached to each other by a hinged connection at a pivot point 30. In one example embodiment, the second component 20 is a fixed component attached to the frame of the feed conveyor 50, and the first component 10 is pivotable about the pivot point 30. That is, the feed chute cover is foldable. In one example embodiment, the hinged connection includes conventional hinge devices, such as holes and pins or shafts located on both sides of the feed chute cover.

[0027] The feed trough cover also includes a biasing element 40, which is configured to assist in pivoting the first component 10, i.e., to provide a force to cause the first component 10 to... Figure 1 The first position shown is easier to lift. The biasing element 40 is also configured to mitigate, delay, or prevent the first component 10 from descending to the first or closed position, or to the third or maintenance position, by providing a force that partially counteracts the gravitational force caused by the weight of the first component 10, as will be referred to below. Figure 3 Please provide an explanation.

[0028] In one example embodiment, the biasing element 40 includes a spring, for example Figure 1 The depicted tension spring is attached between the first component 10 and the second component 20 in a manner that it is stretched in a first position and a third position. Although Figure 1 A tension spring is schematically shown, but in one embodiment, the spring comprises another type of spring, replacing the tension spring, or a spring other than a tension spring. In an example embodiment, the biasing element comprises at least one torsion spring surrounding a hinge pin or shaft, or a leaf spring attached to the first component 10 and the second component 20. The spring, as a biasing element, provides function without using external energy and is a lightweight element that does not significantly increase the mass of the feed chute cover.

[0029] In an example embodiment where the biasing element 40 includes a tension spring, the spring is stretched at a first position of the first component 10.

[0030] In yet another example embodiment, the biasing element includes a pneumatic or hydraulic element configured to provide the same function as a spring, i.e., to provide force to cause the first component 10 to... Figure 1 The first position shown is easier to lift. It also slows down the descent of the first component 10 to the first position, the closed position, or the third position.

[0031] In yet another example embodiment, the biasing element includes a counterweight configured to be attached to the first component 10 in a manner that provides the same function as a spring, i.e., to provide a force to cause the first component 10 to... Figure 1The first position shown is easier to lift and slows the descent of the first component 10 to the first position, the closed position, or the third position. In this example embodiment, the positioning and weight selection of the counterweight minimize the additional weight added to the feed chute cover.

[0032] In one example embodiment, the feed chute cover also includes at least one locking device (not shown) configured to prevent pivoting of the first component 10 and to lock the feed chute cover in a first, second, or third position. While the weight of the first component 10 alone would be sufficient to keep it substantially stationary in the first and third positions, in one example embodiment, at least one locking device is provided to further enhance security. In one example embodiment, the locking device includes conventional devices such as pins or latches.

[0033] Figure 2 A side view schematically showing the crusher feed chute cover in a second position according to an example embodiment is shown. Figure 2 It shows the relationship with Figure 1 Same components. Figure 2 The second position shown is the neutral position, in which the biasing element 40 does not apply any force to the first component 10. In an example embodiment where the biasing element 40 includes a spring, in the second position of the first component 10, the spring is in a neutral, stationary, or unloaded state, such as a tension spring that is not stretched.

[0034] In one example embodiment, the first component 10 is manually lifted from a first position to a second position. The force provided by the bias element 40 facilitates the lifting, making the operation easier and improving safety.

[0035] Figure 3 A side view schematically showing the crusher feed chute cover in a third position according to an example embodiment is shown. Figure 3 It shows the relationship with Figure 1 and Figure 2 Same components. Figure 3 The third position shown is both a maintenance and transport position, in which the first component 10 pivots on top of the second component 20. The biasing element 40 slows the descent of the first component 10 to the third position by providing a force against the weight of the first component 10. In an exemplary embodiment where the biasing element 40 includes a tension spring, the spring is stretched in the third position of the first component 10.

[0036] Figure 4 A side view schematically showing the crusher feed chute cover in a fourth position according to an example embodiment is shown. Figure 4 It shows the relationship with Figures 1 to 3The same components. The first component 10 and the second component 20 pivot in the same position as in the third position. The fourth position is the transport position of the mineral material processing equipment, in which the feed conveyor 50 has been removed from the crusher 100 and lowered to reduce the height of the mineral material processing equipment. The feed chute and feed chute cover are removed and lowered to the transport position at the side of the crusher 100 as the feed conveyor descends.

[0037] Figure 5 A side view of a mineral material processing apparatus according to an example embodiment is shown schematically. Figure 5 A mobile mineral processing apparatus 500 with an mounting track according to an example embodiment is shown. In one example embodiment, the mineral processing apparatus 500 includes a frame (or body) 110, a track base 120, a feed conveyor 50, a feed hopper 130, and a crusher 100. In one example embodiment, the crusher includes a cone crusher or a rotary crusher.

[0038] The mineral processing equipment 500 also includes a motor unit 140 for driving the crusher 100 and a conveyor 150 for conveying the crushed material (e.g., to a stockpile). In one example embodiment, the mobile mineral processing equipment 500 can be moved by other tools such as wheels, sliders, or outriggers. In another example embodiment, the mineral processing equipment 500 is stationary. It should be noted that in one example embodiment, the mineral processing equipment 500 includes... Figure 5 Other elements not shown in the diagram.

[0039] Mineral material processing equipment 500 also includes the above-mentioned... Figures 1 to 4 The feed trough cover includes a first component 10 and a second component 20. The feed trough cover is shown in a first position, i.e., in the operating or closed position.
