Ball grinding mill, energy saving ball mill for sand/stone production

Ball grinding mill brief introduction and application:

Ball grinding millis vital equipment for grinding many kinds of mine materials. Particle size depends on entirely the time how long the energy saving ball Mill runs. Ball mill is widely used in various fields, such as cement industry, new construction materials, refractory materials, chemical fertilizer industry, glass industry, black and non-ferrous metal ore dressing and glass ceramics production industry. All in all, ball mill is suitable to all kinds of ores and other materials through dry or wet grinding.

Ball grinding mill main structures:

Ball grinding millis mainly made up of feeding part, discharging part, reducer, small transmission gears, motor, electric control and other major parts. Hollow shaft adopts steel castings materials and lining systems can be changed very early. Rotating big gear processes in the way of casting rolling gear. The cylinder body has wear-resisting lining board, which has good abrasion resistance

Ball grinding mill working principle:

Cylinder body has the lining plate, which can protect the shell from wearing out. When the feedstock is put into the cylinder body, under the centrifugal force and the friction by the steel balls, the materials can be smashed, the powder can be discharged through the stripper plate, and the whole processing is finished.

The basic principle of steel ball selection:

1. The diameter of the steel ball is mainly based on the hardness of the materials.
2. If the ball mill has large diameter, it will has huge impact, so we can choose the smaller steel ball.
3. The ball mill uses double storehouse clapboard should have smaller steel ball compared with the single one.
4. Generally, we keep to the level four principle, there are little large and small steel balls, that is, we mainly use middle size as the grinding medium.
