AI Technical Summary

Technical Problem

In the existing technology for preparing aluminum fluoride, the low efficiency of crushing and grinding waste aluminum electrolyte leads to poor sieving effect and affects the overall preparation efficiency.

Method used

The device, which combines an inner liner plate with grinding steel balls and an air supply component, enables efficient grinding and screening of waste aluminum electrolytes. The rotation of the inner liner plate and the coordination of the air supply component form a "water curtain" type grinding and screening, thereby improving the preparation efficiency.

Benefits of technology

This method enables thorough grinding and efficient sieving of waste aluminum electrolytes, improving the efficiency of aluminum fluoride preparation and simplifying the replacement and maintenance process of the inner liner.
