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 2022 5 11 For seeds perlite can be applied to propagate
