There is no ultra fine mill before, the first set powder grinding mill used in stone powder making was Raymond mill, it's developed in 1906 by C.V.Grueber, a Germany engineer, so we said the ultra fine mill's development based on Raymond mill, they are similar in some point, such they are using a vertical sturcture, they are space saving..., but they are more difference in their processing. As we all know that the Raymond mill is mainly used in coase minerals powder making, the final powder fineness not less than 200 mesh sue Raymond mill process is pretty good. However, ultra fine mill is one kind of superfine powder grinding machine that means, the ultra fine mill usually used in 300-2500 mesh minerals powder grinding, such as: limestone, gypsum, kaolin, marble, fluorite, calcite, dolomite, calcium carbonate and so on. 

However, the most advantage of ultra fine mill is long sercvice. Ultra fine mill grinding roller, grinding ring with high-tech materials made to enhance the stability of equipment operation, extending the life of the ultra fine mill. Compared with the general grinding mill, which has many performance advantages:

1.Roller, grinding ring grinding curve with a new design, which greatly improves the efficiency of the ultra fine mill, disposable product fineness can reach the standards;

2.In fineness of materials and finished the same circumstances, it is the general life of wearing parts grinder 2-3 times;

3.Ultra fine mill absence rolling grinding chamber and a screw, so there is no problem of wearing bearings and seals, to reduce the consumption of wear parts.

That's why ultra fine mill can have a long service life, but besides the long servie life of ultra fine mill, what other advantages the ultra fine mill has?

High efficiency: Under the same finished final size and the same motor power, the capacity of ultra fine mill is twice as much as jet mill, mixing grinder and ball mill.

High safety and reliability: As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

High fineness and flexible adjustment: The final fineness of the grinding materials made by ultra fine mill can be adjusted between 300 mesh and 2500 mesh, and the product fineness can reach D97≤5um.

Environment-friendly: The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
