Ball mill is widely used in building material, and chemical industry. There are two ways of grinding: the dry way and the wet way. Ball mill can be divided into tabular type and flowing type according to differentexpelling mine. To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.
How to choose China vertical roller mill (the output is more than 300t/d) The vertical roller mill has a grinding fineness of 200-400 mesh, so the general processing material yield is large, and the grinding is not as fine as the Raymond mill, resulting in a decrease in yield. The grinding materials generally used for the concrete and cement mixture are ground by vertical roller mill.
