AI Technical Summary

Technical Problem

Existing tailings recovery devices suffer from problems such as low space utilization, insufficient automation, dust leakage, and secondary pollution, making it difficult to achieve efficient and unified collection and transportation of tailings from multiple sources.

Method used

The system employs a blower, vacuum tank, and tail powder receiving assembly. The tail powder generated by the cooling sieve and cyclone separator is centrally transported to the raw material distribution silo via a negative pressure pipeline. Combined with a vacuum system, the tail powder is automatically recovered and transported. The design of the air inlet and connecting pipe enhances the tail powder suspension effect and reduces the risk of blockage.

Benefits of technology

It improved raw material utilization, reduced production costs and labor intensity, reduced dust leakage and environmental pollution, and improved production efficiency and automation.
