Vertical mill is the indispensable machine in grinding industry because it will be extensively used in cement industry, electricity, metallurgy ...
4. Grinding process. In the ball mill, the material is mainly crushed by impact and friction. In the vertical grinding mill, the material is mainly extrusion, and grinding is the auxiliary. The residence time of the material in the vertical mill is 23 minutes, while in the ball mill it takes 1520 minutes.
Abstract. LOESCHE vertical roller mills are widely used for the comminution of raw materials in the cement industry, for the comminution of clinker and blast furnace slag and for the production of pulverized coal for cement kilns, blast furnaces and power plants. Recent research has shown, that the application of these vertical roller mills in ...
