Analysis of advantages of coal gangue ultrafine vertical mill, The design concept is innovative, the structure design is more reasonable, the whole is compact, the floor space is small, and it can be arranged in the open air;

The grinding efficiency is high and the energy consumption is low. The grinding roller directly grinds the ground material on the grinding disc. 

The wear is small and the service life is long. The grinding roller and the grinding disc are not in direct contact, and the grinding roller and the liner are made of high-quality materials, so the wear is less and the service life;

The coal gangue powder is of good quality, the material stays in the mill for a short time, avoids repeated grinding, and the composition is stable, so the finished product has good grain shape and stable quality;
