（1）Advantages of Raymond Mill
As an environmental protection mill, the Raymond mill has many advantages, good performance, stable operation, high cost performance, and more grinding materials, which can meet the production of 80-400 mesh powder. Compared with R-type machine, it can increase production by more than 40%, save 30% of power consumption, and the equipment is used pulse dust collector, with dust collection rate reaching 99%, and the equipment is more environmentally friendly. The mill is easy to maintain, and the grinding ring is not removed to maintain; Moreover, the high powder yield, small vibration and low noise can create a wider economic and social benefits.
