Summary of common questions about 400-500 kg pulverizers:

I. Repair of wear on pulverizer grinding rollers and grinding disc liners

During use, once a fit clearance appears between the pulverizer grinding roller body and the wear-resistant liner, wear between the body and the liner will intensify. In addition, the continuous scouring of the fitting surface by hot air and cement particles leads to the formation of grooves, causing impact collisions between the body and the liner. In severe cases, this causes the liner to crack or even fracture and damages the machine, especially the reducer, resulting in serious incidents.

Once such problems occur, general repair methods are difficult to solve, and replacement costs are high. The excellent mechanical properties and good plasticity of polymer composite materials make it possible to solve this problem.

II. Repair of wear in pulverizer grinding roller bearing housings

The assembly requirements for pulverizer grinding roller bearings are relatively strict, and enterprises generally use the method of cooling the bearings in dry ice for assembly. Once a clearance appears between the bearing and the bearing housing, it will affect the normal operation of the bearing, cause the bearing to heat up, and in severe cases lead to bearing burning. Fushilan technology has the characteristics of being fast, simple, and easy to operate, and in many cases can be repaired on site.

III. Treatment of leakage in pulverizer reducers

Leakage in pulverizer reducers not only affects the appearance of the machine, but also wastes oil and causes great trouble for equipment repair and maintenance.
