gyratory crusher and roll crushers. For very large ore pieces that are too big for receiving hoppers of mechanically driven crushers, percussion rock breakers or similar tools are used to break them down to size. The mechanism of crushing is either by applying impact force, pressure or a combination of both.

Crushers : Smooth Roll Crushers Heavy smooth faced metal rolls turning on parallel horizontal are working elements of smooth roll crusher. Particles of feed caught between the rolls are broken in compression and drop out below. The rolls turn towards each other at the same speed. They have relatively narrow faces (300917mm)

The comminution principle, which is a compression as a breakage mechanism used in the HPGR, is different from the one in conventional crushers or tumbling mills where impact and abrasion breakage mechanisms are dominant. In the HPGR, contrary to the conventional crushing rolls, the particles are broken by compression in

Crushing Principles of Mechanical Crushing

Crusher Operation • Relation between Feed size and Shape – The greater reduction ratio the worse particle shape. – Inter particle breakage improves shape. When crushing a bed of material weaker particles will break first. Flaky or elongated particles are weaker then round. – Breaking round particles gives flaky material. F l a k i n e s ...

Abstract Discrete Element Method (DEM) simulation using a breakage model is applied to study a broad range of existing compression based crushers to better understand machine level operation and to demonstrate that such modelling is now possible. Predictions for five types of crushers: jaw crusher, cone crusher, gyratory crusher, impact crusher and double roll crusher are presented.
