AI Technical Summary

Technical Problem

The existing roller mill drive system suffers from problems such as long spare parts downtime procurement cycle, frequent failures, inability to be operated remotely, significant safety hazards, and low level of intelligence, which cannot meet the needs of intelligent transformation of mines.

Method used

The system employs an intelligent high-voltage switchgear with remote electric operation and status monitoring functions. It uses domestic high-voltage frequency converters that support PROFIBUS-DP communication and domestic high-voltage motors equipped with temperature monitoring elements. The system controls the frequency converter via a host computer for frequency setting, status monitoring, and fault reset. The control program is optimized to achieve functions such as delayed shutdown of the fan, speed detection of the conveyor belt, and remote fault reset.

Benefits of technology

It significantly improved equipment reliability and intelligence, reduced the number of failures and processing time, saved energy consumption, reduced reliance on imported spare parts, and enhanced the system's intelligence and security.
