An impeller is disclosed for use in a centrifugal impact rock crusher. The crusher includes a cylindrical housing and an impact surface positioned radially around the housing interior.

However, the energy associated with the double impeller impact crusher is much higher and energy intensification, rather than energy efficiency, is the main gain of the double impeller design.

Quick impeller bar changes and quick change breaker plates allow for better control of product size. Rugged design and construction give you the continuous high quality output you need to add profit to your bottom line.

Further DEM simulations were done on a crusher with a second impeller installed. The energy spectra and threshold energy levels calculated from the drop-weight test were used as the basis of comparison. The simulations indicate that even at much lower speeds, the performance of a double impeller impact crusher is exceedingly superior.

The impeller assembly of a centrifugal rock crusher is secured removably to a dovetail coupling member secured to a mounting member attached to the turntable of a centrifugal rock crusher. The impeller member has a mating dovetail shape cavity on its face trailing the direction of rotation of the turntable and configured to match the dovetail configuration of the coupling …

A HSI-crusher has an impeller that is made to rotate around a horizontal axis. Pieces of rock are fed towards the impeller and are struck by beater elements mounted on the impeller. The pieces of rock are disintegrated by being struck by the beater elements, and are accelerated and thrown against breaker plates, often referred to as curtains ...

Centrifugal impact crusher machines have a rotating impeller table on which are mounted table liners and shoes for directing rock, or other material to be crushed, dispersed by a centrally mounted feed cone positioned on the rotating table outwardly against stationary anvils. The herein disclosed machine is comprised of impeller shoes which are removably attached to table …

A wide range of impeller/anvil designs are available to suit your different materials and applications. The material to be crushed is fed through the feed hopper. It then falls onto the center of the rotating table. The ejectors impellers (on the table) drive the particles towards the anvils located on the outer ring. 1 1 2 4 3 4 3 2
