Roller Crusher,HPGR Crusher for Sale

Rolls crushers are now emerging as the latest, most powerful and most efficient type of crusher, normally acting in the role of tertiary crusher. The current interest is due to the recent success of the studded roll design, which has overcome many of the roll wear problems that were severely hampering the success of this type of crusher. With the ability to operate a single crusher at +5MW (the most powerful cone crusher currently available is 1 MW), one single rolls crusher has the potential to replace many cone crushers operating in parallel to achieve the same duty.

Essentially a rolls or HPGR crusher consists of two parallel rotating rolls turning together (in opposite directions and turning in the direction of the downward material flow through the centre), with feed being directed through the moving gap between them. One roll is fixed, and the other moveable, using hydraulic pressure. As the ore moves through the gap, the hydraulic force behind the moveable roll acts to crush the particles as they are forced together into a crushed particle “bed”.

Each roll is equipped with its own motor, up to 2.5MW on each. One single rolls crusher can process up to 2,000 tph of ore being fed to it. Operating with high pressures normally results in a product that contains a significant amount of ultra-fines (crushed particles less than 1mm), which provides a favourable ore size distribution for ball mill feed.
