Combined raw coal feeder is designed for its installation under raw coal storage hopper and intended for feeding and batching solid fuels with unsatisfactory loose properties with a tendency for agglutination and sealing.

Combined raw coal feeder is a welded steelwork and includes the following units: dozing machine housing, dozing machine drive, transporting conveyor, transporting conveyor drive. Dozing machine is mounted under the raw coal hopper and provides the coal continuous feed from the hopper and material uniform movement in the hopper throughout its section. The dozing machine construction excludes clogging, hanging and elutriation of coal in the hopper.

The output of combined feeder is regulated by two methods: adjustment by means of layer control device and continuous automatic adjustment by means of electric motor rotation frequency variation in the range of 1500–300 rpm. Feeders are manufactured with right and left arrangement of dozing machine and conveyor drive depending on the Customer requirement.
