AI Technical Summary
In the existing lithium cobalt oxide production process, the centrifugal force generated by the high-speed rotation of the blades causes some raw materials to be thrown away from the blades, making them unable to be fully crushed and resulting in unsatisfactory crushing effect.
A pulverizing device for lithium cobalt oxide production is adopted. Through the combined design of a toothed rod, ball screw, slider, actuating rod, movable frame, sector teeth, toothed rod, pusher plate, active bevel teeth, driven bevel teeth, rotating shaft and pulverizing blade, the device utilizes a motor to drive the ball screw to rotate, which in turn drives the slider to reciprocate. The active bevel teeth rotate, which in turn drives the driven bevel teeth and pulverizing blade to rotate. The pusher plate pushes the raw material towards the pulverizing blade. Combined with the design of the guide plate and the blocking plate, intermittent feeding is achieved to avoid excessive feeding at one time.
It achieves thorough pulverization of lithium cobalt oxide raw materials, avoids blade jamming, and improves pulverization efficiency and thoroughness.
