Ball mill Ф900×1800

horizontalfor coal grinding

Ball mill Ф900×1800 is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is mainly applied in many industries, such as ferrous&non-ferrous metal mine, building materials, chemical, electric power, coal, traffic, light industry, etc. In our company, this series of high-efficiency ball mill adopts rolling bearing support instead of sliding bearing support with bearing bush. Therefore, it can save energy by 10-20%. According to different discharging ways, it can be divided into two kinds, grate type and overflow type. Features 1.Reliable performance .more than 100 years of history. 2.Easy operation, due to structure is simple. 3.Convenient in maintenance. Working Principle The Ball mill Ф900×1800 can be divided into lattice type and overflow type according to different beneficiation methods, and this machine is two lattice-type ball mill. The materials from the feeding fittings enter the first bin of the milling machine via the feeding hollow axis evenly when it works. There is a ladder-like or ripple-like scaleboard in the first bin, and different specification steel balls are installed in the bin. When the cylinder rotates, which generating centrifugal force to carries steel balls to a certain height and then balls fall to strike and grind the material. Model: Ф900×1800 Cylinder rotary speed(r/min): 39 Loading ball weight(t): 1.5 Input size(mm): ≤20 Discharge size(mm): 0.075-0.89 Capacity(t/h): 0.8-2 Motor power(kw): 18.5 Weight(t): 4.6
