Ecoman offers Vertical Shaft Impactors. Ecoman manufactures Grizzly Feeders, Double Roll Crushers, Reciprocating Feeders, Conveyors, Jaw Crushers, Vibrating Screens, Lump Breakers, etc. The Vertical Shaft Impactors is a Centrifugal "Stone-Pump" in which stones are fed into centre of the rotor [like water in the centrifugal pump] and stones are thrown outwards towards the periphery by centrifugal force. The Vertical Shaft Impactors is available in two types, Stone-on-Stone type and Stone on Steel Type.
Stone On Stone Type Vertical Shaft Impactors: Rotor is so designed that, stone layer gets formed on the vane & breaking surface is also formed by material built up. This reduces the wear on the vanes & also on breaker walls. But this cushioned surfaces, reduce considerably the amount of crushing. But amount of spare consumption also gets reduced.
Stone On Steel Type Vertical Shaft Impactors: In this type of VSI, material glides on the metallic steel vanes & after getting released from rotor, hits on the metallic steel surfaces. Naturally wear on, vane surfaces & breaker surfaces are high. Bigger feed sizes up to 100-150 are possible. Ratio ot reduction is high.
