Overview  of ball mill
Ball mill is the key equipment after the material is broken. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal processing, glass, ceramics etc. industry production of all kinds of ores and other materials may be grinding of dry or wet grinding. Ball mill is suitable for grinding all kinds of ore and other materials, is widely used in mineral processing, building materials and chemical industries, can be divided into two types of dry and wet grinding. According to different ways of mine drainage, can be divided into two types of lattice type and overflow type.
Working principle of ball mill
Mill is a component is composed of cylinder body level, and feeding hollow shaft and grinding head, cylinder body is a long cylinder, cylinder is provided with the grinding body, cylinder body is made of a steel plate, steel lining plate and the cylinder body is fixed, the grinding body generally steel ball and according to different diameter and a certain proportion is arranged in the tube, grinding body also available steel.
According to the granularity of abrasive material should be selected, materials by ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, friction force, making it attached to the barrel lining board is take the cylinder, when they were brought to a certain height when, due to its own gravity and being thrown off, whereabouts, grinding body like a projectile will materials in the cylinder body to break.
Performance characteristics of ball mill:
1. The main bearing adopts a large diameter double row aligning stick bearing, instead of the original sliding bearing, the friction is reduced, the energy consumption is reduced, and the mill is easy to start.
2. The structure of the end cap of the ordinary mill is preserved, and the large diameter inlet and outlet is large.
3. The feeder is divided into combined feeder and drum feeder two, simple structure, split installation.
4. Without the inertia shock, the equipment runs smoothly, and the mill stop time is reduced, and the efficiency is improved.
