  2. 衬板类产品特征 Specialties of Liner sort
  2.1 沟槽衬板Grooved liner
  沟槽衬板将球取衬板之间的点接触变成120° 弧线打仗,增大了研磨面积;沟槽内始终存有料垫,进步了研磨效力,并减轻了球取衬板的间接金属磨损;活化衬板、环沟衬板、螺旋沟槽衬板、锥面衬板、挡料环等多型式的组合,可使钢球发生正分级,取物料的粉磨历程相符合;安装体式格局可用螺栓流动,亦可镶砌。技术指标:减产5%;节电8%;一致筛余细度下,进步水泥比表面积~15m2/kg;一致材质下,低落钢球磨耗,延伸衬板寿命。
  Grooved liner transform point contact of balls and liners to 120°curved contact which enlarges the grinding area; Material bed laid in groove enhance the grinding efficiency and reduce direct metal abrasion between balls and liners; Combination of active liner, ring grooved liner, spiral grooved liner, cone liner and damming ring make balls positive classified and conform to the grinding process of materials; Liners can be fixed with bolts or inlayed.
  Technical Index: Output increased by 5%. Power consumption reduced by 8%. With same residue of sieve, specific surface area of cement is raised by 15m2/kg. Other things being equal, the ball abrasion wear is reduced and the service lifetime of liners is extended.

  Control Flow Screening Diaphragm used in open-circuit mill screen out grains of more than 2mm, which are sent back to the first chamber for future grinding. Damming rings are installed in the fine grinding chamber to control flow velocity of materials, stir grinding media in the retention section, increase cutting and rubbing. Φ8×8~Φ16×16 micro-cylpebs can be used for fine grinding fully. Then the production can be increased by 20%. Control Flow Screening Diaphragm can also be used in closed-circuit mills whose specific surface area is required to exceed 380 m2/kg and mills for grinding ultra-fine fly ash and slag. The chamber length, liner structure, outlet grate plates, gradation of grinding media must be considered together.
