[0032] Since the fixed plate 10 and the support plate 8 are two groups, a total of two groups are at the bottom of the dry separation box 1, and through the cooperation between the support plate 8 and the fixed plate 10, stable support is provided for the dry separation box 1, and the stability of ore crushing and iron concentrate powder extraction is ensured.

[0033] The reinforcing rib 9 is fixedly installed at the included angle of the support plate 8 and the fixed plate 10, and the reinforcing rib 9 is in a triangular shape.

[0034] Since the reinforcing rib 9 is in a triangular shape at the included angle of the support plate 8 and the fixed plate 10, and the triangular shape has the characteristics of stability, the stability of the support plate 8 and the fixed plate 10 during use is ensured, and the use efficiency of the support plate 8 and the fixed plate 10 is improved.

[0039] The working principle and use process of the utility model are as follows:

[0040] Before the staff needs to dry select iron concentrate powder, the ore needs to be crushed, the ore is poured into the inside of the dry separation box 1 through the feeding port 2, then the motor 3 is started, the first gear 5 is driven to rotate by the motor 3, the first gear 5 and the second gear 6 are engaged, the second gear 6 and the second crushing roller 23 are driven to rotate by the first gear 5, the first crushing roller 22 is driven to rotate by the first gear 5, the ore is crushed through the engagement between the second crushing roller 23 and the first crushing roller 22, the driven wheel 21 is driven to rotate by the first crushing roller 22, the transmission belt 20 and the driving wheel 19 are driven to rotate by the driven wheel 21, the rotating shaft 17 is driven to rotate by the driving wheel 19, the shunt roller 18 is driven to rotate in the inside of the dry separation box 1 by the rotating shaft 17, the ore is shunted by the shunt roller 18, and thus the crushing of the ore is completed.

[0041] Before dry separation of iron concentrate, the worker needs to install the collection box 12 inside the dry separation box 1, and then collect the dry separated iron concentrate. By holding the pull rod 29, the worker moves the positioning block 27 inside the dry separation box 1. The positioning block 27 compresses the spring 28, causing it to pass through the interior of the dry separation box 1 and enter the interior of the box body 30. Then, by holding the push rod 13, the worker pushes the bottom mounting plate 25 of the collection box 12 into the slide chute 24. When the mounting plate 25 is fully inside the slide chute 24, the worker releases the pull rod 29. At this point, the positioning block is in place. Block 27 is quickly pushed into the positioning hole 26 by the spring 28. The positioning block 27 limits and fixes the mounting plate 25. Now the crushed ore flows into the magnetic screening screen 11 through the filter plate 4. If the ore particles are still larger than the mesh of the filter plate 4, the filter plate 4 will block the ore particles and screen them again. When the ore flows into the upper part of the magnetic screening screen 11, the iron concentrate inside the ore will be adsorbed into the magnetic screening screen 11. The non-magnetic ore powder will be left into the collection box 12. Then the iron concentrate inside the magnetic screening screen 11 can be collected.
