PURPOSE: A loss-in weight type automatic constant feed device for a granular material is provided to precisely control the feeding of a granular material when the granular material is transferred. CONSTITUTION: A loss-in weight type automatic constant feed device for a granular material comprises a hopper (100), a transfer screw part (200), a loss-in weight sensor (300), and a controller (400). The hopper receives a granular material therein. The transfer screw part feeds the received granular material. The loss-in weight sensor is formed on one side of the bottom of the hopper and measures the weight of the granular material received in the hopper. The controller controls the operation of the transfer screw part according to the measurement value from the loss-in weight sensor to feed the constant amount of the granular material. |
