Abstract
A receiving chamber receives a material heated in a heating chamber. An injecting shaft of an injecting machine slurries the material crushed by cutters downstream of the receiving chamber and feeds the slurried material to an injection port formed between the fore ends of the shaft and injecting chamber so that the slurried material is gradually accumulated in the port. The shaft is retracted by counteraction from the slurried material accumulated in the port, over a distance proportional to a current accumulated amount of the material in the port. The current accumulated amount of the material in the port can be detected from a current position of the shaft, and then it is determined whether the detected current accumulated amount has reached a predetermined amount. When the current accumulated amount has not reached the predetermined amount, the cutters and injecting shaft are further driven until the predetermined amount is reached. The receiving chamber has a pair of passage sections on its outer surface in opposed relation to each other, which function both as light beam passages for light emitting and receiving elements that are provided on the sections for detecting whether a heated material is in the receiving chamber, and as inert gas supply passages to direct inert gas into the receiving chamber.
