1. The ball mill summerize
The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material.

2. Working principle of ball mill
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
3. Structure of the ball mill
The ball mill is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The iron ore wet grinding ball mill is with stable and reliable working condition.
4. Features of the ball mill
1. There are bearing type and bearing bush type ball mill. The former type, which is the traditional type, is used for large processing capacity because it can work overload . While the latter type, which is energy-saving, is usually used for smaller capacity as it can not work overload.
2. Simple structure, and split installation.
3. The ball mill is easy to lift it while installing and maintaining.
4. Its feeders are classified into two types: combined feeder and cylinder feeder.
5. Moreover, there are dry ball mills and wet ball mills for choice, according to different materials and discharging methods. our company supply the wet ball mills to customer.
