Abstract

PURPOSE: To reliably and stably control the fed powder amount by providing a flow limiting hopper in a powder system and controlling the motor of a feeding mechanism by means of the powder level in the hopper.
CONSTITUTION: Powder contained in a container 1 is fed by a feeding transport unit 2 driven by a drive mechanism 11 having a motor 12, and is conveyedthrough a belt conveyor 13 onto a hopper 4 on a measuring instrument 3. The powder level in the hopper 4 is detected by a level switch 5, which produces an output signal for detect by a level switch 5, which produces an output signal for detect the normal zone passing time required for passing from below to above the normal level zone between the lower limit level and upper limit level by the powder level so as to estimate the feeding capacity with the length of the time as feeding capacity equivalent predetermined. The signal thus obtained is fed from a circuit 9 to a speed setting potentiometer 10 so as to thereby control the speed of the motor 12.
