The vertical roller mill in which grinding, drying and separating are bined has good performance in drying and grinding. The process unit is mature. The three air blower system is equipped. According to the crude fuel chemical position and design clinker position, the raw material proportions and the raw material consume and the productivity requested of the raw material grinding system’s are calculated. The gas and the dust removal system are designed according to the putation of grinding system’s hot working parameter. The design has submitted flow chart 1 and horizontal section chart 6.
