Abstract

PURPOSE: To measure the water content with good accuracy, by detecting the water content of casting sand dropped from a plurality of slits different in the width with a plurality of sensors and suitably combining the detection and operation of each sensor.
CONSTITUTION: The casting sand is fed to the trough providing a plurality of slits different in the width from the kneader, and the sensors 12PW14P detect from which slit the casting sand drops. The output of each sensor 27 is input to the memory operation unit 30, the water content is operated and indicated at the indication control unit 30'. The unit 30' further controls the control valve 32 to adjust the additional water content for the kneader 26.
