Abstract
An apparatus for the reclamation of molding sand by which the quality of the reclaimed molding sand is enhanced. The apparatus for reclamation of molding sand includes a part for feeding the molding sand, which part has a sand falling port at its bottom, a rotary drumdisposed below the part for feeding the molding sandand being rotatable horizontally, a motor driving meansfor rotating the rotary drumby an electric motor, a rollerdisposed in the rotary drumand spaced apart therefrom, and a cylinderconnected to the rollerthat presses the rollertoward the rotary drum. It further includes a flow detector for the sand A disposed at the sand falling port of the part for feeding the molding sand and for detecting the flow of the sand fed into the rotary drum; a current detector B for detecting the current of the motor driving means; a pressure controller C for controlling the pressure of the cylinder; and a controller D for controlling the force of the cylinderthat is pressing the rollerbased on the flow of the sand detected by the flow detector for the sand A.
