How to reduce the wear of vertical mill grinding roller
2017-06-15 | Editor:
As the main parts of vertical roller mill, grinding roller is used to grind complex materials often containing some hard impurities, such as quartz, iron. Thus grinding rollers always are worn badly after a long term's grinding. That will make the clearance between grinding table and grinding roller become larger and larger, then efficiency of vertical roller mill decreases, and energy cost increases.
So how to reduce the wear situation of the grinding roller, thereby improve the production efficiency, and reduce the cost of enterprise? After many years' research and develop, CHAENG (Xinxiang Great Wall Steel Casting Ltd) is able to provide advance, strongly wear-resistamt and long life serviced grinding roller for the current market.

1. Adopt ZG30Mn material, with high hardness and good wear resistance.
2. Professional NDT instrument test for quality assurance.
3. Grinding roller can be taken out of mill through arm, easy to maintenance.
4. Excellent workmanship and smooth surface, conducive to grinding efficiency.
5. High strength, good crack resistance.
6. Adopt arc gouging process for the finish of the grinding roller, so that the appearance quality of the cast steel grinding roler can be guaranteed;
7. Check the stress surface of grinding roller before leaving the factory, to ensure the afe and stable operation.
