How to choose China vertical roller mill (the output is

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.
