Apparatus for supplying raw materials at constant amounts

Abstract

An apparatus for supplying raw materials at constant amounts has a raw material tank for storing and feeding raw materials, a belt for transferring raw materials, a level control guide for defining a thickness of raw materials on the belt, and a belt cover. The apparatus further includes a reversible belt drive motor for controlling a rotation direction of the belt forward and backward and a device for removing raw materials arranged at a backward side of the belt. In the case of supplying the raw materials at constant amounts, a normal operation of supplying the raw materials is performed by rotating the belt in a forward direction. In the case of removing the raw materials arranged on the belt and in the raw material tank, the raw materials are transferred to the device for removing raw materials arranged at a backward side of the belt by rotating the belt in a backward direction so as to remove the raw materials from the belt and the raw material tank.
