Centrifugal type Stone Pump is designed in a way where stones are fed into centre of the rotor and stones are thrown outwards towards the periphery by centrifugal force. The Stone Pump is equipped with horizontal rotor rotating at speed of 55m/sec to 65m/sec. The Stone Pump ensures that the crushed material falls through the annular open ring area by gravitational force. The Centrifugal type Stone Pump is designed with maximum feed size of 0.16 mm.
