AI Technical Summary

Technical Problem

The existing cement roller presses do not have screening components, which causes incompletely crushed limestone particles to mix into the limestone powder, affecting product quality and making it difficult to crush again.

Method used

A screening assembly, including a screen cylinder, a rotating plate, a return box, and a return assembly, is installed in the roller press. The incompletely crushed limestone particles are fed back to the crushing roller for further crushing through the screening and return assembly.

Benefits of technology

This effectively prevents incompletely crushed limestone particles from mixing into fully crushed limestone powder, thus improving product quality. Repeated crushing ensures complete crushing of limestone, thereby enhancing the quality of cement production.
