what is a vertical shaft impactor (vsi) primer?,when it comes to producing materials such as aggregate for road making, vsi crushers use a high-speed rotor and anvils for impact crushing rather than compression force for the energy needed for size reduction. in a vsi, material is accelerated by centrifugal force by a rotor against the outer anvil ring, it then fractures and breaks along natural faults throughout the rock or minerals..choosing a mobile impact crusher for recycling – what you,the impact crusher is a first- and second-stage crusher in one unit, so you can crush a 600-mm product down to a final product for resale as recycling aggregate. 'our machines are excellent in recycling asphalt, as we can slow down the rotor speed to crush the asphalt, but not the aggregate inside the asphalt, so the material can be reused in.impact crusher machines,typically, impact crushers either use gravity to drop material onto a surface, or the material is fed into a chamber containing a high-speed rotor with hammers or blow bars that collide with the material and propels it at a very high force onto breaker plates for further size reduction..
