Teeth Roller, Welding Roller
– Roller Crusher Wear Parts
Teeth Roller is the main wear part of Roller Crusher, our material is high manganese steel with tungsten, tin, chromium and other rare metals. Very wear-resistant and high temperature resistant with can reach to HRC58~HRC63.
The hardness is the most essential factor of the products. Because of the advanced process, our teeth rollers contain a service life 50~100% longer than those made of traditional high chromium iron.
