Grinding Balls/Rods in the Mill, grinding the raw mineral ores into fines size required. With the mills rolling, the alloyed liners also special designed to lift the grinding media and improve grinding effects.

SAG MILL liners usually use Cr-Mo alloy liners, 8.8 class grade Bolts, together with Forged steel balls. So that can endure high strength impact. Widely used in Medium- Large Metal Mining companies

A grinding balls test is taken on a big Pb&Zn mine in Central Asia. During a 2 months trial in individual selected ball mills,Huihe's High Cr ball's successfully pass the customer's wear rate test. l

Cement ball mill liners, usually use High Cr, Medium Cr, Cr-Mo alloy as materials, which has advantages of high hardness: 40-55HRC, so means better wear resistance performance.
