Rotor Weighfeeder - FB-IWF/M

Rotor Weighfeeder

Product Introduction:

Fengbo Rotor Weighfeeder is mainly applied for continuous gravimetric weighing of pulverized coal in the cement calcination process. The process of coal discharging, weighing and conveying to pneumatic transmission pipe is all finished in this enclosed structure.
Fengbo Rotor Weighfeeder adopts the operation principle of gravimetrically measuring horizontal rotor. Bulk material is discharged from the bunker through rotor, brought to weighing area, and then sent to the pneumatic transmission pipe after measurement and at last sent to the process by the air from the air fan. The weighing shaft passes through the outlet of the material and the disconnectable coupling between pneumatic pipe and rotor which means that it can compensate the secondary load reaction caused by pressure fluctuation and do not influence the material measurement results. Whenever the material passes the weighing area, its weight will be measured by weighing device. Material weight and position are all stored in the electronic system of the feeder, namely, the load condition of every part of the rotor has been got before the discharge. In order to make the pre-setting value match the material quantity stored in the storage house, angular velocity of rotor required in the discharge position has been calculated and finished by the rotor driving device. Through this pre-control principle, the rotor weighfeeder can calibrate any fluctuation and offer high accuracy.
