摘　　要：介绍了生料粉磨系统由辊磨系统改为辊压机终粉磨系统的情况。新粉磨系统在V型选粉机前加装了密封喂料机,选用了高效节能风机,将收集成品的旋风筒改为2个,将气动闸板阀改为气动棒阀,采用永磁电机驱动。改造后,生料粉磨系统产量从430t/h提高到500t/h以上,系统电耗从15.7kW·h/t降至10.8kW·h/t。The situation of the raw meal grinding system being changed from the original roller grinding system to the final grinding system of the roller press is introduced.The new grinding system is equipped with a sealed feeder in front of the V-type powder separator,and a high-efficiency energy-saving fan is selected.The cyclone for collecting the finished product is changed to two,and the pneumatic gate valve is changed to a pneumatic rod valve,which uses permanent magnets motor for driving.After the transformation,the output of the raw meal grinding system was increased from430 t/h to more than 500 t/h,and the power consumption of the system was reduced from 15.7 kW·h/t to10.8 kW·h/t.
