Directional sanding equipment for solid electrolyte after calcination

Abstract

The invention relates to directional sanding equipment for a solid electrolyte after calcination, and belongs to the technical field of mills. The equipment comprises a shell, a hollow spline shaft arranged in the shell, and a sanding assembly sleeved on the spline shaft and driven by the spline shaft. The sanding assembly sequentially comprises a centrifugal mechanism for centrifugal classification, a blade sanding mechanism for preliminary crushing and a spiral sanding mechanism for fine sanding from top to bottom. And a conveying auger is arranged in the spline shaft, and is used for upwards conveying sanded materials in a cavity at the lower part of the bottom of the equipment to the centrifugal mechanism. Qualified fine materials are separated out by the centrifugal mechanism to serve as finished products, and coarse materials automatically return to the blade sanding mechanism through a falling hole to be reprocessed, so that an efficient closed-loop circulating system is formed. According to the device, collaborative operation of crushing, sanding, grading and internal circulating conveying is achieved, the production efficiency and the uniformity of the product particle size are remarkably improved, meanwhile, an external heat dissipation structure is arranged, and the stability of the machining process is guaranteed.
