Description

Technical Field

[0002] When recycling the positive and negative electrode materials of the battery, sponge nickel will be obtained. The sponge nickel needs to be processed into nickel powder, which requires the use of a nickel powder crushing and grinding device.

[0003] The current nickel powder crushing and grinding device, for example, a ball milling device for nickel powder production proposed in publication number: CN219632605U, is a ball milling device for nickel powder production. The nickel raw material is placed into the ball mill shell through a feed hopper, and a motor is started to drive gear 1 to rotate, thereby driving gear 2 and a rotating shaft to rotate. The ball mill shell is driven to rotate through the rotating shaft to crush the nickel raw material through grinding balls. During the rotation of the ball mill shell, the inner wall of the ball mill shell is cleaned by an L-shaped cleaning brush and an L-scraper to prevent nickel powder from adhering to the inner wall of the ball mill shell and clogging the powder outlet hole, thereby reducing the waste of nickel powder, thereby achieving the effect of reducing production costs.
