The results show that the wear of the roller and scaleboard includes mainly three coexistent mechanisms: cutting wear, plastic deformation wear and brittle-fracture-peeling wear.
结果表明：显微切削、反复塑变和断裂剥落三种磨损机理并存，其中以反复塑变磨损为主。

After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scaleboard with steel ball inside to grind material.
物料在第一仓达到粗磨后，经单层隔仓板进入第二仓，该仓内镶有平衬板，内有钢球，将物料进一步研磨。
