FIELD: machine building.
SUBSTANCE: feeding hopper comprises a hopper connected with a casing of a delivery screw conveyor which is fitted by an output branch pipe, is fixed on two supports, consists of a shaft and a screw element and is driven, the feeding hopper is equipped by a crushing device. The crushing device comprises a casing connected to the output branch pipe. Two double-support crushing rollers of a gear wheel type - a driving one and a driven one - are installed in the upper part of the crushing device casing under the output branch pipe parallel to the delivery screw conveyor and are engaged with each other by their geared surfaces. The shank end of the delivery screw conveyor is placed beyond its casing and is coupled with the shaft of the driving crushing roller of a gear wheel type by a pinion drive so that the crushing rollers in the upper part rotate towards each other. An unloading branch pipe is located in the lower part of the crushing device casing.
EFFECT: improved reliability and smaller dimensions.
