抄録

Since pumping efficiency of a rotor in Warman-Flotator is not sufficiently high, it is necessary to consider the following iteme in order to increase self-air-inhaling capacity and to decrease the power consumption:<BR>(a) To decrease submergence of the rotor for reducing air-intake resistance.<BR>(b) To enlarge bottom clearance of the rotor for decreasing inlet resistance caused by pulp circulation over the cell bottom.<BR>(c) To combine the rotor with stabilizers for ensuring necessary, agitating flow over the cell bottom. For these requirements the present writers have come to the following conclusion through their experiments;<BR>(1) Bottom clearance had each optimum values for obtaining maximum self-air-inhaling capacity and minimum power consumption, which was reduced by increasing peripheral speed of the rotor.<BR>(2) Also, submergence had an optimum value. Power consumption was decreased by reducing the submergence, but self-air-inhaling capacity was decreased with the submergence at higher peripheral speed of the rotor.<BR>(3) Self-air-inhaling capacity was decreased by the increase of recirculating, dispersed air bubbles into the rotor, in case of the excess bottom clearance as well as below optimum submergence.
