Ball Mill

The Classification of Ball Mill

Based on different grinding methods of adding water or not, ball mills are divided into dry type ball mill and wet type ball mill. In general, we use the wet type ball mill for the ore beneficiation.

The dry type ball mill is mainly used for producing powder type materials like coal powder.

The Ore Discharging Methods of Wet Type Ball Mill

Based on different ore discharging methods, ball mills are divided into grid shaped one and overflowing one. A grid shaped scale board is installed at the end cover of the grid shaped ball mill, which makes the qualified materials be discharged out of the ball mill through the scale board's gap. As for the overflowing ball mill, it discharges ores by adding water into the other end of the ball mill and once the water flows over the horizontal level of the ball mill's discharging end, the ore pulp will overflow out.

The Working Principle of Ball Mill

Energy saving ball mill machine is a horizontal cylindrical grid-shaped rotating device with the outer gear transmission, two positions. Materials pass through the feeding device into the first bin of the ball mill spirally and regularly via the hollow shaft. The first bin has ladder plate or corrugated plate inside which has installed steel balls with different specifications. The cylinder rotates and produces centrifugal force to raise the steel balls up and then to fall from a certain height, thus generating the force to impact and grind the materials. After the coarse grinding in the first bin, the materials enter into the second bin via the single deck bulkhead. This bin covered with a flat liner plate with steel balls inside will do further grinding of the materials. Powdery materials are discharged through the unloading grate board. This is the whole grinding procedure of ball mill machine or ball grinding machine.

The Advantages of Ball Mill

1. Large capacity and continuous operation

2. Big feeding port,strong wearproof ability

3. Barrel lining and grinding media can apply various abrasive materials

4. Even granularity of the finished products

5. High wearproof ability increase the service life

6. Adopting new-type bearings reduces the energy consumption

The ball mill is a common grinding machine used to grind all kinds of minerals and produce ore pulp. The ball mill grinder made by the Chinese ball mill manufacturers is applied in industries of cement production, refractory matter production and ceramics.
