design of ball mill size reduction in usa pdf Size Reduction The rate of particle size reduction increases with frequency of stress application and magnitude of the stress. However, particle size reduction rate typically decreases during the grinding process, for example, due to the increase in fracture resistance of the smaller particles. 1
Get Pricegrind size. For any process, including ball mill circuits, we can say that output equals input multiplied by efficiency*. Output = Input x Efficiency In a ball mill circuit, the output can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies

Each of these theories was useful in the design and scale up of' ball mill operations, however they told little of the expected size distributions, and most importantly gave no indication of liberation. Later work done by Hukki (1975) attempted to show the validity of each theory within a certain particle size range
