Energy-saving Overflow Ball Mill

Energy-saving overflow ball mill

1)Product advantages
1.Energy-saving grate ball mill is easy to start and save energy up to 20-30%
2.Energy-saving grate ball mill adopts groove-type circular lining plate that is instrumental in increasing contact areas of iron balls and ores

2)Product feature
1 The transmission machinery of Energy-saving overflow ball mill substitutes large-scale double row self-aligning roller bearing for sliding bearing, so it is easy to start and saves energy by 20-30%.
2 Energy-saving overflow ball mill adopts groove-type circular lining plate that is instrumental in increasing contact areas of iron balls and ores, which enhances grinding action and ore lifting capacity and decreases energy consumption.
3 Energy-saving overflow ball mill adopts whole milling house, which makes construction and installation easy.
4 Energy-saving overflow ball mill is configured with bigger discharge opening and has huge processing capacity.
5 Energy-saving overflow ball mill is equipped with oil-mist lubrication device which guarantees smooth operation of gears.

3)Product application
Energy-saving overflow ball mill is usually used for ores with higher grinding fineness

4)Product principle
Its main component is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding. The continuous feeding of ores can create considerable pressure to make ores move from feed opening toward discharge opening. Finally, acceptable particles are discharged from the discharge opening. Acceptable ore particles are carried away by water by wet mill, or by air by dry mill. The hollow shaft comprises reciprocal screw impellers that can carry overflowed iron balls and coarse ores back to mill. Energy-saving overflow ball mill has simple structure and higher operation rate. Equipped with rolling bearings, it can considerably save energy.
