MBM Medium Speed Coal Mill
Brief IntroductionThis mill adopts German advanced-milling technology. Combining the characteristics of similar domestic products, it is a kind of new-typed moderating-speed coal mill, which is developed on the basis of RP; Its components are newly developed. This machine is of scientific design and superior performance. It is the optimal milling equipment in electric power, metallurgy and cement industries.
It consists of motor, reducer, case, milling device, separator, outlet, coal feeding pipe, loading device, control box and sealing apparatus. The fittings are all of superior performance in the world at present. We ensure good quality and durability of the whole machine.

1) The concrete base weight required is only 3 times of that of other similar machines thus the construction expenses is greatly reduced
2) Small vibration while using and doesn't need shock-absorbing device
3) Large load adjustment scope, so it can run under various environments
4) Can bear very strong explosion pressure
5) The grinding roller adopts new material and new craft, which ensures long service life and low maintenance cost
6) There is gap between the grinding parts; it can start with load or offload
