AI Technical Summary

⚠Technical Problem

The existing wear-resistant plates for coal mills have low overall strength and poor resistance to deformation. Furthermore, when a part is damaged, the entire plate needs to be replaced, resulting in material waste.

⚗Method used

The cylindrical wear-resistant plate is made of arc-shaped splicing plates. The two ends of the splicing plate frame are pressed together with clamping rings and fixed by splicing bolts. A high-chromium alloy weld overlay layer is set on the inner side to improve strength and wear resistance.

🎯Benefits of technology

It improves the overall strength and deformation resistance of the wear-resistant plate of the coal mill, facilitates assembly and fixing, and allows for individual replacement of the arc-shaped assembly plate in case of local damage, saving materials and extending the service life of the equipment.
