The ore is transported to the feed pipe 3 above the sorting machine through the action of the transmission mechanism, and then the ore enters the feed pipe 3, and the ore entering the feed pipe 3 then enters the box body 1, and then the ore falls and collides with the guide plate 15, and then the ore falls into the conveyor belt 10, and the motor 4 is started by the PLC controller 8, and the motor 4 starts to drive the active roller 5 to rotate, and the active roller 5 rotates to drive the conveyor belt 10 to rotate, and the conveyor belt 10 rotates to drive the ore to move, and when the ore moves to the driven roller 9, the ore enters the first material box 12, the second material box 13, and the third material box 14 according to the grade.

[0026] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the dust removal assembly 2 includes a dust collecting plate 208, which is installed on the side of the box body 1. A conical tube 207 is installed at the center of the side of the dust collecting plate 208 away from the box body 1. The conical tube 207 is connected to a connecting tube 206, and the connecting tube 206 is Z-shaped. The other end of the connecting tube 206 is connected to a collection box 201. The lower part of the collection box 201 is slidably engaged with a drawer 202. The upper part of the collection box 201 is provided with a card slot 203, and the card slot 203 is movably engaged with a filter plate 204. The side of the collection box 201 is provided with a card slot 203. There is an air hole 209, and the air hole 209 is connected to the fan 205. A plurality of evenly distributed dust suction holes 210 are provided on the side of the dust collecting plate 208 facing the box body 1. The fan 205 is started, and the air inside the box body 1 is sucked into the conical tube 207, and then the air enters the connecting tube 206. Under the action of the fan 205, the air enters the collecting box 201. The dust-containing air entering the collecting box 201 is blocked by the filter plate 204, and the dust falls into the drawer 202, thereby realizing the dust removal of the ore.

[0027] Working principle: During ore sorting, after the ore is crushed and screened, it is transported to the feed pipe 3 above the sorting machine through the action of the transmission mechanism, and then the ore enters the feed pipe 3, and then the ore enters the box 1, and then the ore falls and collides with the guide plate 15 (on the one hand, the guide plate 15 collides with the ore to raise dust, and on the other hand, the impact of the ore on the conveyor belt 10 increases the service life of the conveyor belt 10), and then the ore falls into the conveyor belt 10, and the motor 4 is started through the PLC controller 8, and the motor 4 starts to drive the active roller 5 to rotate, The rotation of the active roller 5 drives the conveyor belt 10 to rotate, and the rotation of the conveyor belt 10 drives the movement of the ore. When the ore moves to the driven roller 9, the ore enters the first material box 12, the second material box 13, and the third material box 14 according to the grade (for metal ores, the higher the ore grade, the greater its specific gravity. For example, the skarn copper ore has an ore specific gravity of about 3, while the ore-free waste rock has a specific gravity of about 2. At the driven roller 9, the initial velocities of the ore and the waste rock are the same. The ore with a high specific gravity will mostly fall into the first material box 12, and the waste rock with a low specific gravity will fall into the third material box 14, thereby realizing the sorting of the ore and waste rock).

[0028] When the ore enters the feed pipe 3, the fan 205 is started, and the fan 205 starts to draw the air inside the box 1 into the conical tube 207, and then the air enters the connecting pipe 206. Under the action of the fan 205, the air enters the collecting box 201. The dust-containing air entering the collecting box 201 is blocked by the filter plate 204 (the filter plate 204 is set to filter the dust, and the dust is convenient to fall into the drawer 202). The dust falls into the drawer 202, and the ore is dusted. Through the setting of the dust removal component 2, the dust content in the ore is reduced, thereby reducing the amount of flotation reagents used in the next step, and it is also convenient to recover useful materials, making the mineral processing process smoother.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
