Roller mills are mills that use cylindrical rollers, either in opposing pairs or against flat plates, to crush or grind various materials, such as grain, ore, gravel, plastic, and others. Roller grain mills are an alternative to traditional millstone arrangements in gristmills. Roller mills for rock complement other types of mills, such as ball mills and hammermills, in such industries as the ...
As cement producers continually seek reduced energy consumption and lower maintenance costs, two emerging trends are changing the face of cement production: the use of grinding stations that support variable feed materials and more widespread use of vertical roller mills (VRMs).
