Mineral Processing Equipment : Capacity closed circuit ball milling - A type of mining equipment that can trigger the development and change of the beneficiation technology industry. The main core machines are ball mills, rod mills, flotation machines, magnetic separators, etc.
The role of classification in milling appears to have been neglected in the current efforts to reduce the energy consumption of grinding. two past approaches, experimental and modelling, for quantifying the effects of classification efficiency and circulating load on the capacity of closed ball mill circuits, are revisited and discussed in this.
For a closed circuit ball mill flowsheet as represented in figure 2, a simplified relationship (equation 1) for relative capacity at different circulating load and classification efficiencies was.
Given mill is doubled by including a closed circuit classifier producing a 200% circulating load. similarly, by increasing the circulating load to 500% the capacity factor increases to 2.3. figure 1. effect of circulating load on mill capacity  research into the subject of classification efficiency effect on grinding circuit capacity was.
