Crusher - an overview | ScienceDirect Topics

A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 6.1.3 Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, like chalcocite and chalcopyrite they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size.

N2 - Mathematical modeling in conjunction with mineral characterization is widely used as a method for design and optimization of comminution circuits, to simulate the processes of crushing, grinding and classification. An important input parameter to the simulation models is the Run-of-Mine Particle Size Distribution (ROM PSD).

Sepro Improves Mineral Processing With Microwave Technology

Without screening material before grinding circuits, valuable energy is spent crushing and grinding all input material, no matter its worth. The microwave process allows valuable minerals to be separated from waste material prior to grinding, directing energy where it matters most. It also creates microfractures in the ore, reducing the energy ...
