Abstract
PURPOSE: To adjust the moisture of powder and granules such as molding sand continuously and accurately by measuring the moisture content and temp. of powder and granules as well as their mixture, controlling the amount of addition of insufficient moisture with respect to a target value and alarming and indicating abnormality of the measured values.
CONSTITUTION: Powder and granules such as molding sand in a storage tank 1 are supplied to a sand mill 3. After a fixed time since charging of a required amount of molding sand, the temp. and moisture content of the molding sand prior to mixing flowing on a belt conveyor 2 and the temp. and moisture content of the molding sand after mixing with the sand mill 3 are measured with respective thermometers 11, 13, and moisture meters 12, 14, and these are inputted to a microcomputer 15. The computer 15 converts these input signals into numerical values and operates an alarm device 17 when the measured values are out of set values. The computer 15 also obtains the moisture addition amount required for adjusting the moisture to a target moisture content, and controls the revolution of a motor 6 which drives a pump 5.
