AI Technical Summary

Technical Problem

Bentonite particles are easily formed into lumps due to moisture during grinding, and adhere to the grinding rollers, affecting the grinding efficiency and reducing the particle fineness, resulting in a decline in the production quality of the plugging agent.

Method used

An energy-saving electric grinding device including a drive assembly, grinding balls and a scattering plate is designed. The heat of the drive motor is used to dry the material through a vent pipe and a heating wire, and the coordinated movement of the scattering plate and grinding balls achieves synchronous crushing and grinding, reducing the drive source and rationally utilizing heat to improve grinding efficiency.

Benefits of technology

It effectively prevents bentonite particles from agglomerating, improves grinding efficiency and the fineness of bentonite particles, and improves the production quality of plugging agents.
