AI Technical Summary

Technical Problem

In the production of reduced iron powder, the mismatch between the powder cake conveying speed and the crushing device rotation speed leads to the powder cake overlapping and accumulating, which in turn causes the crushing equipment to overload and affects production safety.

Method used

A radio switch is used to detect the position of the powder cake in real time. An audible and visual alarm is triggered, and a telescopic cylinder is used to control the baffle to block the upper layer of powder cake, preventing multiple layers of powder cake from entering the crushing device. The combination of an adjusting ring and a vertical rod structure makes it easy to adjust the height of the radio switch.

Benefits of technology

It effectively prevents powder cakes from overlapping and entering the crushing device, improving production safety and reducing production interruptions and equipment maintenance costs.
