Principle and Applications of Grinding Wheel Regenerator
Grinding wheel regenerator is composed of grinding wheel, fluidized bed, airblower, motor and dust-removal system. After being put into regenerator, used-sand is in the fluidized state under the action of airflow. Grinding wheel, buried into sand, rotates with high speed. During above process, strong collision and friction are caused between sand and high-speed rotating grinding wheel, machine body and sands, which make adhesive film peeled off and used-sand regenerated. The paper introduces operation principle of grinding wheel regenerator and studies experimentally about the influence of regenerator’s rotate speed on sand breakage rate. The study reveals that rotate speed has effect on breakage rate of reclaimed sand. Sand breakage rate increases with the raising of rotate speed.
