Grinding Media Wear Rate Calculation in Ball Mill
- In any mill, the rate at which the weight of any ball decrease is directly proportional to its weight.
- In any mill, the rate at which the diameter of a ball decreases is directly proportional to its diameter.
- In any mill, the rate at which the surface of any ball decreases is proportional to its surface.
- In any mill, the rate at which the weight of any ball decrease is directly proportional to its weight.
- In any mill, the rate at which the diameter of a ball decreases is directly proportional to its diameter.
- In any mill, the rate at which the surface of any ball decreases is proportional to its surface.
- Since the rate at which a ball loses weight varies as the work done upon it in the mill, it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball. This is se...
