Abstract:
A molding sand reclamation method and reclamation system effectively separates magnetically attracted matter from molding sand. The molding sand reclamation method includes removing metal powder and metal pieces by magnetic separation with a first magnetic flux density and removing magnetically attracted matter by magnetic separation with a second magnetic flux density higher than the first magnetic flux density from molding sand separated from a casting by shot blasting, and removing by dry mechanical reclamation, from the molding sand, substances including carbonized matter adhered to the surface of the molding sand.

Claim (Index 39):
The molding sand reclamation system according to  claim 38 , wherein the mechanical reclamation system further comprises:\n a roller pressing mechanism that is coupled to the roller and that presses the roller, with a constant pressure, towards the inclined circumferential wall; a motor driving means for rotating the rotating drum by using a motor; a sand flow rate detector that is installed at the sand dropping port of a sand loading portion and that detects the flow rate of loaded sand; an electric current detector that detects an electric current value of the motor driving means; a pressure control means for a cylinder that is the roller pressing mechanism; and a control means for adjusting a pressing force of the roller due to the cylinder in accordance with the sand flow rate detected by the sand flow rate detector; and the control means comprises: a target electric current computation unit that is preset with a correlation between the sand flow rate and an electric current value for the motor determined by differences in a level of polishing required for reclaimed sand, and that calculates a target electric current value of the motor corresponding to the sand flow rate detected by the sand flow rate detector so as to maintain the correlation; a comparison unit that compares the target electric current value of the motor, corresponding to the flow rate of the loaded sand, with an electric current value of the motor as actually measured during operation; and a control unit that adjusts the pressing force of the roller due to the cylinder, based on results from the comparison unit, so that the electric current value of the motor during operation is the target electric current value of the motor.
