Abstract
A material calibrator for weighing coal and powder feeder is characterized in that a demarcation hopper comprises an upward connection flange, a demarcation hopper, a downward connection flange and a coal output flashboard. A supporting frame comprises the surrounding steel rack of the demarcation hopper, which suspends on the supporting frame by a weighing sensor, and the supporting frame is connected to upward connection flange by four hung pole, and positioning device is defined to make the demarcation hopper suspend on the supporting frame. The weighing sensor, a module, a weighing instrument and a junction box constitute the metering system. The weighing instrument is equipped in the control tank. A self-inspection system comprises poise, a poise elevator and a control switch, and the poise elevator is hung on the external wall of the demarcation hopper. The utility model is used to calibrate the material for the weighing coal and powder feeder directly.
