OSTI.GOV Technical Report: Optimization of Comminution

OSTI.GOV Technical Report: Optimization of Comminution

Jul 01, 2005 Abstract. The goal of this project was to improve energy efficiency of industrial crushing and grinding operations (comminution). Mathematical models of the comminution process were used to study methods for optimizing the product size distribution, so that the amount of excessively fine material produced could be minimized

The energy efficiency of ball milling in comminution

The energy efficiency of ball milling in comminution

Nov 01, 2002 In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill

Impact Crusher Working Principle

Impact Crusher Working Principle

Jun 23, 2015 Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them.Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill)
