Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
A wet grinding ball mill is a grinding process using a liquid suspension or slurry, providing efficient and effective particle size reduction in wet conditions.
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
The principle of wet ball milling is based on the energy transfer between the grinding media and the material being ground. In the process of wet ball milling, the grinding media are typically made of steel or ceramics, and they are loaded into the mill in a specific proportion. As the cylinder rotates, the grinding media and the material being ...
