Abstract：By optimizing the roller press system and ball mill system,adjusting the position of grinding aids,optimizing the dust into the process of selecting powder machine,the output of cement grinding system is increased.Through the use of air suspension fan,inverter fan transformation,elimination of high energy consumption air compressor and other measures to upgrade the auxiliary equipment to improve the efficiency of the fan and air compressor,the technological process of grinding system was optimized by removing belt machine,skirt board machine,spiral conveyor of dust collector,air chute of grinding tail dust collector,reforming ash hopper and cyclone tube.It achieved the fine management of grinding system due to reducing the idle and low-load operation time of the equipment,reducing the compressed air leakage of the grinding system,optimizing the spray frequency and piping arrangement of the dust collectors,and using electricity to avoid peak-to-valley production and operation.After transformation,the power consumption of cement preparation section is reduced from 34.9 kW·h/t to 30.8 kW·h/t,which can meet the requirement of national standard.
