ball mill efficiency equation

Ball Mills - an overview | ScienceDirect TopicsBall mill external appearance and internal view. Ball mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to .Factors Affecting Ball Mill Grinding EfficiencyThe following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different ...The energy efficiency of ball milling in comminution - .1/11/2002· Schellinger's calculated ball mill efficiency, in dry or wet ball mill grinding, ranges between 10% and 19%, with the higher figure occurring at the optimal mill loading. In terms of the Brace and Walsh surface free energy of quartz, his results give a ball mill efficiency that is less than 0.5%.(PDF) Effect of circulating load and classification .The Functional Performance Equation for ball milling circuits allows us to isolate the circuit classification system efficiency (CSE) from the mill's grinding performance.
