ABSTRACT:
Mineral impact breaking apparatus uses a divided flow with the first part of the flow being accelerated preferably through a rotor and discharged towards an impact breaking surface. The second part of the mineral flow is introduced into the path of the accelerated first part of the flow so that there is impacting between the first and second flows of minerals and with the second flow acting as anvil blocks against which the first flow particles will be impacted and broken. Where the horizontal accelerating rotor is used to accelerate the first part of the mineral flow the kinetic energy of the rapidly rotating air above the rotor is used to direct an air flow back to the infeed of the rotor and minimize dust discharge.
