Ball Mill

Ball mill is used for grinding materials which have been crushed, it is suitable for cement, silicate products, new building materials, refractory materials, chemical fertilizer, ferrous and non-ferrous metals, glass ceramics and other industries. All kinds of ores can be dry or wet grinding by this mill. Our milling machine can be used for processing barite, calcite, limestone, dolomite, marble, bentonite, talc, mica, graphite, phosphate rock, potash, pumice, and so on. This grinding machine can be divided into grid type and overflow type according to the discharging way of ores.

Working Principle
The centrifugal force generated by the rotation of the roller which can drive the steel ball moving, and impact the materials repeatedly. The following is a detailed process of ball mill: Materials enter the first bin of the mill through feeding device, where is equipped with stepped liner board or corrugated liner board, and steel balls with various of sizes. This bin is used for coarse grinding of the materials. After that the materials enter the second bin of the mill, where is equipped with flat liner board and steel balls, and this bin is used for fine grinding of the materials. The finished powder is discharged by discharge grate.

1. When the diameter of the rod mill is less than 3200mm compared to its conventional configuration, is using a rolling bearing instead of a sliding bush bearing which has energy savings of 20-30%
2. When the diameter of the grinding mill is more than 2700mm of its normal configuration, it is in slow operation for maintenance purposes.
3. Drum feeder, spiral feeder and joint feeder options.
4. The lubrication system uses a thin oil lubricant that is easily applied to the machine.
5. Bearings are lubricated by an automatic grease pump.
6. A series and B series liner plate options. B series plates can save up to 10-20% energy.
