What is a Cone Crusher? Telsmith

Capacities and product gradations produced by cone crushers are affected by the method of feeding, characteristics of the material fed, speed of the machine, power applied, and other factors. Material hardness, compressive strength, mineral content, grain structure, plasticity, size and shape of the feed particles, moisture content will affect

Cone Crushers McLanahan

A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the

DEM modelling of non-spherical particle breakage and flow

Apr 01, 2015  Li et al. (2014) used a spherical DEM model and the particle replacement technique to model a cone crusher but only resolved three daughter particles for each breaking particle. This model used a very simple packing process to determine the positions of the progeny which allowed initial overlap of fragments after packing.

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
