Since 1906 worldwide market leader in designing, manufacturing and servicing vertical roller mills for the cement, power and industrial minerals industries.
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 ...
The vertical roller mill (VRM) which has gained wide acceptance in the cement industry and is used for grinding raw materials (mainly limestone), is a promising alternative.
The paper demonstrates why the Loesche VerticalRollerMill (VRM) is a serious alternative to conventional grinding technologies and where the limitations of the system are.
