SCMN11 mill liner plate in general refers to a kind of casting steel with the Mn content at 11%~22%, the carbon content at 0.9%~1.5%, mostly higher than 1.0%. Under low impact load, can achieve HB300~400, Under high impact load, can achieve HB500~800.Different impact load, the surface hardening layer depth can be up to 10~20 mm. High hardness of hardening layer can resist the wear of grinding media. Under the condition of strong impact abrasive wear, high manganese steel has excellent anti-wear performance, so it is widely used in mining, aggregates, coal industries as wear-resistant parts.
SCMN11 Mill liners need to protect the mill shell from damages due to wear and transmit the energy from the rotating mill to the ball charge.
The rules that guide the design of a liner depend on the grinding mechanisms required for the specific mill. They can be classified either as impact/cataracting for very coarse to coarse grinding, cascading for coarse to medium grinding or attrition for medium to fine grinding.
In any case the design of a liner is a compromise between lifetime and grinding efficiency.
Note : Depending upon the various application, we propose suitable profile with appropriate alloy ranging from 12 to 25% .
