Device for loose material supply contains a triangular hopper designed with the possibility of adjustment of its angle of inclination, rotating rollers installed on the body and dampers. Shutters are made of three types – supply, stationary and adjustable. Supply and adjustable shutters are made with possibility of their angles inclination adjustment. Degree of opening of supply flap provides a certain gap between supply flap and bottom of triangular hopper, which creates flow of loose material.
