thousands of zenith pf series impact crushers are installed all over the world in recent 20 years. it has been proved that this series of crushers not only effectively increase productivity and final product quality, but also greatly reduce the investment costs and operation costs. unmatched excellent performance is shown in the secondary crushing, tertiary crushing and material recovery.
there are two types of impact crushers. the horizontal shaft impact crusher (hsi crusher) and the vertical shaft impact crusher (). the hsi crushers break rock by impacting the rock with hammers that swing on a rotating shaft. the practical use of hsi crushers is limited to soft materials and non abrasive materials, such as lizenithne, phosphate, gypsum, weathered shales. hsi crushers achieve the highest degree of reduction. the vsi crushers can also break rock by impacting the material with rotating hammers, traditionally this is referred to as a “shoe and anvil vsi” and has similar limitations to the hsi crusher. the most outstanding advantage of this machine is that its finished powder is in good, cubic shape and without tensility and cranny.

used pf impact crusher working principle
our impact crusher uses plate hammer on the rapidly rotating rotor to generate high-speed impact to crush the materials in the crushing cavity, and casts the crushed materials along tangential direction to impact plate at the other end of the crushing cavity. the materials are crushed again, and then, they return to the plate hammer to undergo the process above repeatedly.
impact crusher crushing materials with impact force. when materials enter, crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. then materials will be shot back to the blow bar again for the third crush. process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support.
