The roller mill can easily meet the specification of 80 to 600 mesh and is widely used throughout the mining industry. A roller mill works by grinding materials at high speed with a varying number of heavy, cylindrical rollers being spun around a central vertical shaft. The mineral is fed into the machine through a port in the side and is ...
