Detailsspeed is 20–35 m/s for coarse crushing, 35–65 m/s for medium crushing and 50–90 m/s for fine crushing. The best crushing is observed under direct impact when the particle velocity vector and the impact plate surface make an angle of 90°. To estimate the influence of crusher design and particle properties on the crusher performance, the
DetailsSince the crushing plants operate under harsh conditions and involve very abrasive material, multiple factors can influence their performance. This paper assesses a number of factors affecting the performance of the crushing plant by addressing the critical design parameters and consideration of ore characteristics, operability and maintainability.

DetailsHammermills and pure impact crushers have rotating impellers which lift the kinetic energy of the material to a level where, on sudden impingement against a stationary plate, breakage occurs. In the more common jaw- or cone-type crushers, stone either breaks by impact or fails as a result of sufficient compressive or shear forces.
DetailsCompression Crushing: Compression crushing, also known as compressive force, applies a compressive force to the material between two surfaces until it breaks.This way is frequently applied in jaw crushers and cone crushers. In jaw crushers, the material is squeezed between the fixed jaw and the moving jaw.
Detailsmechanism used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. Fracture occurs in the feed material when the strain developed in it due to sufficiently applied impact forces, pressure or shearing effect exceeds the elastic limit .Generally crushers are very rugged, massive and heavy in design.
