the range NP impact crusher is characterised by a unique attachment unit Blow bars are fixed to rotors by a single wedge assembly delivering higher tightening torque than any other manufacturer Combined with perfect blow bar alignment on crossbeam contact faces this guarantees the enormous advantage of eliminating clearance between the rotor
4 Secondary/Tertiary Impact Crusher These crushers are designed to handle smaller feed sizes compared to primary crushers but excel at producing finer end products like gravel or sand 5 Impact Breaker/ Hammer Mill This type of impact crusher uses hammers attached to a spinning rotor to pulverize materials after they have been initially
Djordjevic et al 2003 used the software PFC3D® to describe the motion of particles in a crusher with a greatly simplified geometry demonstrating that collision energies differ from what is expected from theory More recently Duan et al 2011 used EDEM® in simulating particle motion within the rotor of a VSI crusher
