The dry magnetic separator mainly includes a magnetic pulley or a CT-type magnetic drum or a CTDG-type dry magnetic separator or a CTX magnetic drum.

It has been eliminated in the field of magnetite ore sorting. The magnetic system of the CT magnetic drum or CTDG dry magnetic separator is fixed, the magnetic system wrap angle is about 170°, the magnetic field strength on the cylinder surface is 0.2~0.6T, the belt conveyor speed is 1.2~2.5m / s, and the number of magnetic reversals of magnetic particles during dry magnetic separation is small, resulting in dry magnetic separation concentrate mixed with tailings, dry magnetic separation tailings mixed with magnetite ore, and the dry magnetic separation effect is poor.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0042] It should be noted that the commonly used dry magnetic separation process in the relevant technology is fine ore dry magnetic separation, that is, the fine ore under the screen of the closed-circuit crushing and screening operation is subjected to dry magnetic separation to obtain dry magnetic separation concentrate and dry magnetic separation tailings. The dry magnetic separation concentrate is used as the ore to be ground, and the dry magnetic separation tailings are discarded. The dry magnetic separator mainly includes a magnetic pulley or a CT-type magnetic drum or a CTDG-type dry magnetic separator or a CTX magnetic drum.

[0043] Among them, the magnetic pulley has a 360° magnetic system and is fixed and rotated synchronously with the outer cylinder. There is no magnetic reversal and the inclusions are serious. It has been eliminated in the field of magnetite ore sorting. The magnetic system of the CT magnetic drum or CTDG dry magnetic separator is fixed, the magnetic system wrap angle is about 170°, the magnetic field strength on the cylinder surface is 0.2~0.6T, the belt conveyor speed is 1.2~2.5m / s, and the number of magnetic reversals of magnetic particles during dry magnetic separation is small, resulting in waste rock inclusion in dry magnetic separation concentrate and magnetite ore inclusion in dry magnetic separation tailings, and the dry magnetic separation effect is poor.

[0044] The magnetic system wrap angle of the CTX magnetic drum is 360°, the magnetic field intensity on the surface of the outer drum is ≥0.4T, the speed of the sorting belt is ≥2.5m / s, and the magnetic system speed is ≥80r / min. The outer drum and the magnetic system rotate in opposite directions to form a rotating magnetic field. When the magnetic ore particles pass through, rapid magnetic reversal and magnetic stirring occur in the magnetic pole alternation area. Under the combined action of magnetic field force, centrifugal force and gravity, the non-(weak) magnetic waste rock particles mixed between the magnetic ore particles will move to the outer layer due to magnetic stirring, while the magnetic ore particles mixed between the non-(weak) magnetic waste rock particles will move to the inner layer due to the strong magnetic field force, thereby realizing efficient separation of magnetic ore particles and non-(weak) magnetic waste rock particles, and being able to fully discard the non-(weak) magnetic waste rock particles mixed between the magnetic ore particles. The obtained dry magnetic separation concentrate has a high grade and the dry magnetic separation tailings has a low grade, that is, the qualified dry separation waste discarding rate is high and the sorting effect is good.

[0045] The CTX magnetic drum can discard a large amount of qualified tailings, which can reduce the cost of grinding and sorting, thereby significantly reducing the production cost of mineral processing, reducing the amount of fine tailings entering the tailings pond, and increasing the service life of the tailings pond. The coarse tailings have a high utilization value, thereby achieving cost reduction and efficiency improvement in the mineral processing plant.

[0046] However, in the related mineral processing projects, in the built mineral processing plants, because the dry magnetic separation system was not designed and constructed simultaneously, or the sorting belt used by the dry magnetic separator was too long, or the belt running obliquely in the dry magnetic separator was too long and installed at a large inclination angle, it was not suitable to use the CTX magnetic drum 120 to directly upgrade the dry magnetic separation.

[0047] In order to solve the problems existing in the above-mentioned dry magnetic separation production process transformation, the utility model provides a split dry magnetic separator based on a CTX magnetic drum.

[0048] Combination Figure 1 and Figure 2 As shown, a split dry magnetic separator based on a CTX magnetic drum provided according to an embodiment of the utility model includes a magnetic separation mechanism 100, which is fixed at the first ore outlet of the ore dressing mechanism, and includes an electric drum 110, a CTX magnetic drum 120 and a first conveying belt 130. The first conveying belt 130 is wound around the outside of the electric drum 110 and the CTX magnetic drum 120. The first conveying belt 130 is used to transport the finely crushed ore flowing out of the first ore outlet to the CTX magnetic drum 120. The CTX magnetic drum 120 is used to perform dry magnetic separation on the finely crushed ore to obtain dry magnetic concentrate and dry magnetic tailings.

[0049] In the split dry magnetic separator based on the CTX magnetic drum of the embodiment of the utility model, the electric drum 110 drives the first conveying belt 130 to move along the conveying direction, and the first conveying belt 130 receives the finely crushed ore from the first ore outlet and transports it to the CTX magnetic drum 120 for dry magnetic separation. The non-(weakly) magnetic waste rock particles mixed between the magnetic ore particles are subjected to magnetic agitation and leave the first conveying belt 130 under the action of inertia force, and the magnetic ore particles mixed between the non-(weakly) magnetic waste rock particles are adsorbed on the surface of the first conveying belt 130 due to the strong magnetic field force and continue to move with the first conveying belt 130 until they are out of the magnetic suction range of the CTX magnetic drum 120 and then thrown away, thereby realizing efficient separation of magnetic ore particles and non-(weakly) magnetic waste rock particles, and being able to fully remove the non-(weakly) magnetic waste rock particles mixed between the magnetic ore particles, and the obtained dry magnetic separation concentrate has high grade, the dry magnetic separation tailings has low grade, and the separation effect is good.

[0050] It should be noted that the mineral processing mechanism can be a mechanism for conveying or screening ore in the relevant technology. Specifically, it can include the under-screen ore collecting funnel of the screening machine in the screening plant of the mineral processing plant, or the head of a longer fine ore transfer belt conveyor (the head can be a conventional transmission roller or a CT magnetic roller or a CTDG magnetic roller), or the head of a longer and upwardly inclined fine ore transfer belt conveyor (the head can be a conventional transmission roller or a CT magnetic roller or a CTDG magnetic roller).

[0051] The split dry magnetic separator based on the CTX magnetic drum of the embodiment of the utility model does not need to adjust the structure of the original beneficiation mechanism, which avoids the situation that the original beneficiation mechanism cannot be adapted to the installation and maintenance of the CTX magnetic drum 120, effectively reduces the transformation cost of the beneficiation mechanism and facilitates maintenance; and through the CTX magnetic drum 120, a large amount of tailings can be discarded in advance, the amount of ore entering the mill can be reduced, energy saving and consumption reduction can be achieved; the grade of iron ore entering the mill can be greatly improved, the ore sorting process can be optimized, and the sorting cost can be reduced; the amount of fine tailings generated can be reduced, a large amount of fine tailings can be avoided from entering the tailings pond, and the service life of the tailings pond can be increased; the coarse tailings have a high utilization value, thereby achieving energy saving, carbon reduction, cost reduction and efficiency improvement in the beneficiation plant.

[0052] In this embodiment, the magnetic separation mechanism 100 also includes belt rollers 650. Three belt rollers 650 are arranged below the first transport belt 130 along the conveying direction of the first transport belt 130, and are suitable for supporting the first transport belt 130 to improve the stability of the first transport belt 130 in conveying ore; of course, the number of belt rollers 650 can be adjusted according to the length that the first transport belt 130 needs to support (that is, the span between the electric roller 110 and the CTX magnetic roller 120).

[0053] The magnetic separation mechanism 100 further includes a tape anti-deviation vertical stop roller 640, which is symmetrically arranged on both sides of the conveying direction of the first conveying tape 130, and the two ends of the tape anti-deviation vertical stop roller 640 are respectively located on both sides of the forward direction of the first conveying tape 130, to prevent the first conveying tape 130 from gradually deviating from the position perpendicular to the conveying direction during continuous operation, thereby improving the operation stability of the magnetic separation mechanism 100. In this embodiment, two tape anti-deviation vertical stop rollers 640 are respectively arranged on both sides of the first conveying tape 130 along the conveying direction; of course, the number of tape anti-deviation vertical stop rollers 640 can be adjusted according to the length of the first conveying tape 130 (that is, the span between the electric roller 110 and the CTX magnetic roller 120).

[0054] The magnetic separation mechanism 100 further includes a slippage detection device for the electric roller 110 for detecting whether the electric roller 110 is slipping and a bearing temperature detector for detecting the bearing temperature.

[0055] The split dry magnetic separator based on the CTX magnetic drum in this embodiment has a dry magnetic tailings yield of 11.11%, a dry magnetic tailings grade of 12.50% total iron and 0.95% magnetic iron, and the obtained dry magnetic concentrate has a total iron grade of 31.20%, which is 2.08 percentage points higher than the original ore grade of the mill without the split magnetic separator.

[0056] According to an embodiment provided by the utility model, combined with Figure 1 and Figure 2As shown, the split dry magnetic separator based on the CTX magnetic drum also includes a support mechanism 200, which is provided with a magnetic selection position and a maintenance position; the magnetic separation mechanism 100 is suitable for moving and switching between the magnetic selection position and the maintenance position. In the magnetic selection position, the magnetic separation mechanism 100 is located below the first ore outlet, and is suitable for receiving and magnetically separating the fine ore discharged from the first ore outlet; in the maintenance position, the magnetic separation mechanism 100 is avoided above the ore dressing mechanism to form a hoisting space.

[0057] In this embodiment, the support mechanism 200 is used to support the magnetic separation mechanism 100, and the height of the first ore outlet of different beneficiation mechanisms can be adapted by changing the height of the support mechanism 200; the staff can move the magnetic separation mechanism 100 relative to the support mechanism 200. Specifically, after the staff assembles or repairs the magnetic separation mechanism 100, they hoist it to the maintenance position through the hoisting space and connect it to the support mechanism 200, and then move the magnetic separation mechanism 100 from the maintenance position to the magnetic separation position to perform magnetic separation operations; the same is true when repairing the split magnetic separator, and the above process can be reversed.

[0058] By setting up the support mechanism 200 and the magnetic separation mechanism 100 separately, the assembly efficiency of the split magnetic separator is improved and the difficulty of modifying the original mineral processing mechanism is reduced; and the magnetic separation mechanism 100 is moved away from under the first mineral outlet to a maintenance position, which effectively solves the problem of difficulty in maintaining the split magnetic separator due to insufficient space under the first mineral outlet of the original mineral processing mechanism.

[0059] In this embodiment, the magnetic separation mechanism 100 also includes a mobile bracket 140. The electric roller 110, the first transport belt 130 and the CTX magnetic roller 120 can be pre-installed in the mobile bracket 140, and then the mobile bracket 140 is hoisted to the maintenance position of the bracket mechanism 200, thereby effectively improving the installation and maintenance efficiency of the split magnetic separator.

[0060] In this embodiment, the support mechanism 200 is horizontally arranged. Of course, the arrangement of the support mechanism 200 can be adaptively adjusted based on different terrains and the size of the space below the beneficiation mechanism, such as being arranged at a certain inclination angle to the horizontal plane.

[0061] According to an embodiment provided by the utility model, the support mechanism 200 includes a fixed support 210 and a movable support 220, the fixed support 210 and the movable support 220 are detachably connected, the fixed support 210 has a first side and a second side arranged oppositely along a set direction, the first side is arranged for the ore dressing mechanism, and the second side is arranged for the movable support 220. The space above the ore dressing mechanism and the movable support 220 is avoided to form a hoisting space; taking the installation of the magnetic separation mechanism 100 as an example, the staff can connect the movable support 220 to the second side of the fixed support 210 to form a support mechanism 200 with a maintenance position, and then hoist the magnetic separation mechanism 100 to the maintenance position and move it to the magnetic separation position for installation and fixation, and remove the movable support 220 after the fixing is completed. The movable support 220 detachably connected to the fixed support 210 can realize the installation of the magnetic separation mechanism 100 in the limited space below the original ore dressing mechanism, and the removal of the movable support 220 can retain the original space and its function, improve the space utilization rate, and effectively adapt to the ore dressing plant with a small space below the original ore dressing mechanism.

[0062] The maintenance position may be set on the movable bracket 220 . Of course, it may also be partially set on the movable bracket 220 and the rest on the fixed bracket 210 to fit into a narrower space.

[0063] In this embodiment, the movable bracket 220 and the fixed bracket 210 have the same height and width; of course, the movable bracket 220 and the fixed bracket 210 can also have different heights. Specifically, the movable bracket 220 can be connected to the fixed bracket 210 at an axis and swing at a certain angle relative to the extension direction of the fixed bracket 210.

[0064] In this embodiment, the movable bracket 220 and the fixed bracket 210 are connected via a connecting plate 204. Of course, they may also be connected in the form of a snap connection, a magnetic connection, etc.

[0065] According to an embodiment provided by the utility model, combined with Figure 1 and Figure 4 As shown, the support mechanism 200 is provided with at least one guide rail portion 230 extending in a set direction, and the magnetic separation mechanism 100 further includes a roller 141 provided corresponding to the guide rail portion 230, and the roller 141 is used to drive the magnetic separation mechanism 100 to move along the guide rail portion 230. The roller 141 is suitable for reducing the friction between the magnetic separation mechanism 100 and the support mechanism 200, and reducing the installed power of the travel motor.

[0066] In this embodiment, the support mechanism 200 is provided with two parallel guide rails 230, and the magnetic separation mechanism 100 is provided with 2 to 5 pairs of rollers 141 corresponding to the two guide rails 230, and the rollers 141 are connected with travel motors, and the travel motors are used to provide driving force to the rollers 141 to realize the movement of the magnetic separation mechanism 100 along the guide rails 230. Of course, in other embodiments, the connection method of the magnetic separation mechanism 100 and the support mechanism 200 can also adopt the form of hydraulic slide and slider matching, electric lead screw nut matching, wire rope winch matching, etc., so that the magnetic separation mechanism 100 can be moved relative to the support structure and switched between the magnetic separation position and the maintenance position.

[0067] In this embodiment, the support mechanism 200 (including the fixed support 210 and the movable support 220) is composed of a track, a longitudinal beam 201, a column 202, and a foot 203 from top to bottom. A connecting plate 204 is set at the connection between the fixed support 210 and the movable support 220. The ends of the fixed support 210 and the movable support 220 away from the connection are respectively provided with connecting plates 204 fixed to the wall or the column 202; a triangular diagonal brace is provided between the column 202 and the longitudinal beam 201 to increase stability; the connection method of the connecting plate 204 and the fixed support 210 and the movable support 220 is bolted, which increases stability and facilitates the disassembly of the movable support 220. The foot 203 uses a square thick steel plate to increase the support strength and support stability.

[0068] According to an embodiment provided by the utility model, combined with Figure 1 and Figure 2 As shown, the bracket mechanism 200 also includes a limiter 240, which is installed on the guide rail portion 230. The limiter 240 is set corresponding to the magnetic selection position or the maintenance position, and is suitable for preventing the magnetic separation mechanism 100 from continuing to move along the guide rail portion 230 in the direction of separating from the guide rail portion 230 when it is in the magnetic selection position or the maintenance position.

[0069] In this embodiment, the limiters 240 are arranged at both ends of the guide rail portion 230. The limiters 240 can effectively prevent the magnetic separation mechanism 100 from separating from the guide rail portion 230 and causing damage, and the limiters 240 play a positioning role in the movement of the magnetic separation mechanism 100. For example, when the magnetic separation mechanism 100 moves from the maintenance position to the magnetic separation position, when the magnetic separation mechanism 100 touches the limiter 240 and cannot continue to move, it indicates that the magnetic separation mechanism 100 has reached the magnetic selection position.

[0070] In other embodiments, the limiter 240 can also be set on the magnetic separation mechanism 100, and the guide rail part 230 can be correspondingly provided with a block or a slot; of course, the limiting form of the magnetic separation mechanism 100 is not limited to physical limiting, and a sensor can also be set to detect the current position of the magnetic separation mechanism 100, and the travel motor can be controlled to stop based on the position information to achieve the limiting of the magnetic separation mechanism 100.

[0071] According to an embodiment provided by the utility model, combined with Figure 1 As shown, the support mechanism 200 is provided with a dry magnetic concentrate collection hopper 250 and a dry magnetic tailings collection hopper 260. The dry magnetic concentrate inlet and the dry magnetic concentrate outlet of the dry magnetic tailings collection hopper 260 are arranged in sequence from the magnetic separation mechanism 100 to the support mechanism 200. The dry magnetic tailings inlet and the dry magnetic tailings outlet of the dry magnetic tailings collection hopper 260 are arranged in sequence from the magnetic separation mechanism 100 to the support mechanism 200. The dry magnetic concentrate collection hopper 250 is suitable for collecting the dry magnetic concentrate and discharging it from the dry magnetic concentrate outlet. The dry magnetic tailings collection hopper 260 is suitable for collecting the dry magnetic tailings and discharging it from the dry magnetic tailings outlet. While preventing the dry magnetic concentrate and the dry magnetic tailings from being mixed, the discharge range of the ore is controlled to avoid scattering of the ore.

[0072] In this embodiment, the magnetic separation mechanism 100 is further provided with a separation plate 660, which is located between the dry magnetic separation concentrate collection hopper 250 and the dry magnetic separation tailings collection hopper 260. Figure 1 Shown in the figure is the adjustment handle of the separation plate 660. The staff controls the direction and height of the separation plate 660 by adjusting the handle to adjust the proportion of ore falling into the dry magnetic separation concentrate collecting funnel 250 and the dry magnetic separation tailings collecting funnel 260. Reducing the proportion of ore falling into the dry magnetic separation concentrate collecting funnel 250 can effectively improve the quality of the dry magnetic separation concentrate.

[0073] According to an embodiment provided by the utility model, combined with Figure 1 As shown, the split dry magnetic separator based on the CTX magnetic drum also includes a dry magnetic concentrate transport belt (not shown in the figure) and a dry magnetic tailings transport belt (not shown in the figure). The conveying surface of the dry magnetic concentrate transport belt is horizontally arranged and located below the dry magnetic concentrate outlet; the conveying surface of the dry magnetic tailings transport belt is horizontally arranged and located below the dry magnetic tailings outlet.

[0074] In this embodiment, the dry magnetic concentrate discharged from the dry magnetic concentrate collecting funnel 250 is transported to the powder ore bin by the dry magnetic concentrate conveying belt, and the dry magnetic tailings discharged from the dry magnetic tailings collecting funnel 260 is transported to the tailings bin by the dry magnetic tailings conveying belt, thereby realizing automatic classification and collection of ore.

[0075] In this embodiment, different configurations are required to adapt to different beneficiation mechanisms. For example, when the original beneficiation mechanism has a vibrating screen, and no dry magnetic concentrate conveying belt and dry magnetic tailings conveying belt are provided before the transformation, the dry magnetic concentrate can be discharged to the fine ore conveying belt of the original beneficiation mechanism through the dry magnetic concentrate collecting funnel 250, and then a dry magnetic tailings conveying belt can be additionally provided.

[0076] When the original beneficiation mechanism has a long straight belt conveyor transport head wheel or an inclined belt conveyor head wheel, and there is no dry magnetic separation concentrate transport belt and dry magnetic separation tailings transport belt before the transformation, it is necessary to add dry magnetic separation concentrate transport belt and dry magnetic separation tailings transport belt.

[0077] When the head wheel of a long straight belt conveyor or the head wheel of a belt conveyor running obliquely is a CT magnetic drum or a CTDG magnetic drum, the original dry magnetic separation concentrate transport belt and dry magnetic separation tailings transport belt can be used.

[0078] In addition, when there is no dry magnetic separator (CT magnetic drum, CTDG magnetic drum) before the original beneficiation mechanism is transformed, a new tailings bin is required to store the dry magnetic separation tailings.

[0079] According to an embodiment provided by the utility model, combined with Figure 1 As shown, the split dry magnetic separator based on the CTX magnetic drum also includes a dust cover (not shown in the figure) to form a closed working space, and the electric drum 110, the CTX magnetic drum 120 and the first conveying belt 130 are installed in the working space.

[0082] In one embodiment, the first seal 510 is disposed around the dry magnetic separation tailings outlet and has a first end connected to the dry magnetic separation tailings collecting funnel 260 and a second end abutting against the dry magnetic separation tailings transport belt.

[0083] In the above two embodiments, the first seal 510 adopts a contact seal to achieve the sealing between the ore collecting funnel (referring to the dry magnetic separation concentrate collecting funnel 250 and the dry magnetic separation tailings collecting funnel 260) and the conveying belt (referring to the dry magnetic separation concentrate conveying belt and the dry magnetic separation tailings conveying belt), avoiding dust, preventing ore from splashing on the conveying belt, avoiding injury to people and protecting the environment.

[0084] According to an embodiment provided by the utility model, combined with Figure 3 and Figure 4 As shown, the split dry magnetic separator based on the CTX magnetic drum further includes a second seal 520 .

[0085] In one embodiment, the second seal 520 is disposed around the dry magnetic concentrate inlet and has a dust cover at the first end and is connected to the dry magnetic concentrate collecting funnel 250 at the second end;

[0086] In one embodiment, the second sealing member 520 is disposed around the dry magnetic separation tailings inlet and is connected to the dust cover at a first end and to the dry magnetic separation tailings collecting hopper 260 at a second end.

[0087] In the above two embodiments, the second seal 520 is sealed by a Velcro material, which is convenient for temporarily removing the second seal 520 to remove the magnetic separation mechanism 100 and restoring the seal of the second seal 520 when installing the magnetic separation mechanism 100. It plays a sealing and protective role, avoids dust, prevents ore splashing, avoids injury and protects the environment.

[0088] According to an embodiment provided by the utility model, combined with Figure 1 As shown, the split dry magnetic separator based on the CTX magnetic drum also includes a feeding hopper 610. A feeding inlet and a feeding outlet of the feeding hopper 610 are sequentially arranged along the ore dressing mechanism pointing toward the direction of the magnetic separation mechanism 100. The feeding inlet is arranged corresponding to the first ore outlet. The feeding hopper 610 is connected to the installation position of the ore collecting funnel of the ore dressing mechanism.

[0089] In this embodiment, taking the mineral processing mechanism provided with a vibrating screen as an example, the ore collecting funnel under the vibrating screen is partially or completely removed, and the ore feeding hopper 610 of the split magnetic separator is separately manufactured and installed with the help of the installation conditions of the upper opening of the ore collecting funnel under the original vibrating screen, thereby effectively reducing the space occupancy rate of the split magnetic separator. The ore feeding hopper 610 can effectively gather the ore, so that the ore discharged from the ore feeding outlet can accurately enter the magnetic separation mechanism 100.

[0090] As above, when the ore-selecting mechanism is provided with a relatively long straight belt conveyor head or a belt conveyor head running obliquely, a fixed ore feeding bucket 610 may be provided below the relatively long straight belt conveyor head or the belt conveyor head running obliquely.

[0091] In this embodiment, the ore feeding bucket 610 includes an inverted truncated square cone-shaped ore collecting funnel, an upper interface flange connected to the installation position, an ore feeding outlet for easy installation of soft connection sealing material Velcro, and a wear-resistant lining located on the inner wall of the ore feeding bucket to increase the service life of the ore feeding bucket 610.

[0092] According to an embodiment provided by the utility model, combined with Figure 1 As shown, the split dry magnetic separator based on the CTX magnetic drum further includes a third seal 530 , which is arranged around the feed outlet of the feed bucket and has a first end connected to the feed outlet of the feed bucket 610 and a second end connected to the magnetic separation mechanism 100 .

[0093] In this embodiment, the third sealing member 530 is sealed by a soft connection made of Velcro material, which is convenient for temporarily removing the third sealing member 530 to remove the magnetic separation mechanism 100, and restoring the seal of the third sealing member 530 when installing the magnetic separation mechanism 100. It plays a sealing and protective role, avoids dust, prevents ore splashing, avoids injury and protects the environment. Of course, the third sealing member 530 can also be made of other components with sealing capabilities, such as soft curtains.

[0094] According to an embodiment provided by the utility model, combined with Figure 1 and Figure 3 As shown, the split dry magnetic separator based on the CTX magnetic drum also includes a magnetic leveler 620 , which is arranged above the CTX magnetic drum 120 and is suitable for leveling the finely crushed ore on the first conveyor belt 130 .

[0095] In this embodiment, the magnetic leveler 620 (see ZL 202122240179.6) effectively flattens the ore on the first conveyor belt 130, avoids unevenness of the fine ore on the first conveyor belt along the cross section, and improves the dry magnetic separation effect.

[0096] In this embodiment, the magnetic leveler 620 is mainly used to be installed below the ore dressing mechanism with a transmission roller or a CT magnetic roller or a CTDG magnetic roller to ensure that the cross section of the ore feeding from the first transport belt 130 to the CTX magnetic roller 120 is uniform.

[0097] According to an embodiment provided by the utility model, combined with Figures 1 to 3 As shown, the split dry magnetic separator based on the CTX magnetic drum also includes a magnetic guide plate 670, and two magnetic guide plates 670 are symmetrically arranged on both sides of the conveying direction of the first conveyor belt 130, and the bottom of the magnetic guide plate 670 is 1mm to 50mm higher than the upper surface of the first conveyor belt 130, which is suitable for magnetically attracting magnetite particles to achieve sealing between the magnetic guide plate 670 and the upper surface of the first conveyor belt 130.

[0098] In this embodiment, the magnetite particles adsorbed by the magnetic guide plate 670 are used to seal the gap between the upper surface of the first conveyor belt 130 and the magnetic guide plate 670, preventing the ore from escaping from the surface of the first conveyor belt 130 (i.e., the dry magnetic separation area) and causing wear of the dust cover or even ore splashing and injuring people and polluting the environment; and the magnetite particles avoid direct contact between the magnetic guide plate 670 and the first conveyor belt 130, reducing the friction between the two, and effectively improving the service life of the first conveyor belt 130 and the magnetic guide plate 670.

[0099] According to an embodiment provided by the utility model, combined with Figure 1As shown, the split dry magnetic separator based on the CTX magnetic drum also includes a magnetic particle self-rotation induction cleaner 630, which is arranged on the surface of the CTX magnetic drum 120 away from the first transport belt 130 and is suitable for cleaning the surface of the CTX magnetic drum 120.

[0100] The magnetic particle self-rotating induction cleaner 630 (see ZL 201620341625.9) is used to keep the outer cylinder of the CTX magnetic drum 120 clean, thereby increasing the service life of the CTX magnetic drum 120 and the production efficiency of the CTX dry separator.

[0101] The following is an explanation of the actual installation process of the split dry magnetic separator based on the CTX magnetic drum of the utility model:

[0102] Step 1, partially or completely remove the ore collecting funnel under the vibrating screen, make a separate feeding hopper 610 of the magnetic separation mechanism 100, and install the feeding hopper 610 with the help of the installation conditions of the upper opening of the original ore collecting funnel under the vibrating screen; make and install the main body of the magnetic separation mechanism 100 on a mobile bracket 140 equipped with a roller 141, the mobile bracket 140 is driven by a walking motor, and moves to achieve switching between a magnetic separation position and a maintenance position. The magnetic separation position is used for dry magnetic separation production, and is moved to the maintenance position for hoisting and maintenance; the dry magnetic separation concentrate collecting funnel 250 and the dry magnetic separation tailings collecting funnel 260 matched with the mobile bracket 140 are fixedly installed on the fixed bracket 210 below the mobile bracket 140, the dry magnetic separation concentrate is still discharged to the original fine ore conveying belt conveyor, and the dry magnetic separation tailings are discharged to the newly added dry magnetic separation tailings conveying belt conveyor.

[0103] Step 2, make a movable bracket 220 that cooperates with the fixed bracket 210. The movable bracket 220 and the fixed bracket 210 are at the same height and are provided with a guide rail portion 230 extending in the same direction. When the magnetic separation mechanism 100 needs maintenance, the movable bracket 220 is installed to the side of the fixed bracket 210 that is away from the mineral processing mechanism, and the length of the guide rail portion 230 of the movable bracket 140 is extended forward, and the magnetic separation mechanism 100 is partially or completely removed from the magnetic separation position (that is, corresponding to the space below the vibrating screen); and the length of the movable bracket 220 is set according to the maintenance needs and the plant space of the mineral processing plant.

[0104] Step 3, a sealed connection is set between the feed inlet of the feed hopper and the first outlet of the vibrating screen; the dry magnetic concentrate outlet of the dry magnetic concentrate collecting funnel 250 and the dry magnetic concentrate transport belt, and the dry magnetic tailings outlet of the dry magnetic tailings collecting funnel 260 and the dry magnetic tailings transport belt are connected by a first seal 510; the dry magnetic concentrate inlet of the dry magnetic concentrate collecting funnel 250 and the dust cover, and the dry magnetic tailings inlet of the dry magnetic tailings collecting funnel 260 and the dust cover are connected by a second seal 520; the feed outlet of the feed hopper 610 and the magnetic separation mechanism 100 (dust cover) are connected by a third seal 530; the magnetic separation mechanism 100 is provided with a dust cover and is suitable for being connected to the second seal 520 or the third seal 530. That is, the ore separation mechanism points to the direction of the magnetic separation mechanism 100, and the ore from the vibrating screen enters the magnetic separation mechanism 100 for magnetic separation and is discharged to the conveying belt (referring to the dry magnetic separation concentrate conveying belt and the dry magnetic separation tailings conveying belt) to achieve an overall sealing effect.

[0105] Step 4, same as step 1 to step 3, when the ore selection mechanism adopts a relatively long straight belt conveyor head or an obliquely upward belt conveyor head, a split magnetic separator consisting of a feed bucket 610, a movable bracket 140, a fixed bracket 210, and a movable bracket 220 can be set below the relatively long straight belt conveyor head or the obliquely upward belt conveyor head. The belt conveyor head can be a conventional transmission drum or a CT magnetic drum or a CTDG magnetic drum, and the dry magnetic separation concentrate of the CT magnetic drum or the CTDG magnetic drum can be fed to the split magnetic separator for selection to improve the quality of the magnetic separation concentrate, and the dry magnetic separation tailings of the CT magnetic drum or the CTDG magnetic drum can also be fed to the split magnetic separator for scavenging to obtain dry magnetic separation tailings with a lower magnetic iron grade to improve the recovery rate of magnetic iron, and the dry magnetic separation concentrate of the CT magnetic drum or the CTDG magnetic drum can also be mixed with the dry magnetic separation tailings and fed to the split magnetic separator for dry magnetic separation.
