Abstract
PURPOSE: To prevent formation of bridge by blowing the pressurized gas intermittently into the inlet side of a screw feeder under a hopper.
CONSTITUTION: A taper screw feeder 4 is arranged under a hopper 7 for throwing- in material, and in the taper part 5, material is pushed into and compacted, and material seal is performed. Inert gas such as N2 or CO2 is blown into from a blowing-in port 14 by the operation of a valve 13, and dissolution of bridge is performed. Detection of bridge is performed according to the decrease of the torque of the revolution shaft of the feeder or the electric current value of the motor of a driving apparatus 12 which is detected by a detector 23 for torque or electric current, due to the state in which the material on the taper screw 4 is used up through the suspension of feeding due to the generation of bridge and the screw starts idle operation.
