It is an important material for scientific research. Silicon dioxide can be prepared by crushing quartz. The mined quartz ore is crushed, ground, selected, and dried to finally obtain silicon dioxide powder.

[0003] Crushing device: During the production process, unqualified silicon dioxide needs to be recycled. When recycling, a crushing device is needed to crush it so as to better carry out the subsequent recycling steps. There are many types of crushing devices. Taking double-axis crushing as an example, quartz ore is added to the machine, and the ore between the two rollers is crushed by the rotation and extrusion of two crushing rollers.

[0029] Specifically, a stepper motor 508 is fixedly connected to the inner wall of the chassis 2, and the output end of the stepper motor 508 is fixedly connected to one end of the bidirectional screw rod 506.

[0030] Furthermore, the bidirectional screw rod 506 is driven to rotate by the stepping motor 508, and the bidirectional screw rod 506 drives the two threaded sleeves 507 to move. The two bidirectional screw rods 506 are connected by the transmission sprocket 503 and the transmission chain 502 to drive the two rotating shafts 501 to move. When the rotating shaft 501 moves, it drives the worm wheel 505 to move on the outer surface of the worm 510, and finally adjusts the distance between the two crushing rollers 504, thereby achieving adjustment according to the size of the ore and the required crushing degree.
