Abstract

PURPOSE: To extrude always normally without generation of surging even in the extrusion of a mixture containing a large amount of a scrap material with a virgin material. CONSTITUTION: A raw material supply apparatus for scrap mixing in which a mixture of a virgin material (5) and a scrap material (6) is supplied into an extruder (20) with a screw (2) through a hopper (3) is equipped with a quantitative feeder (22) for the virgin raw material connected to the first driving motor (30) for supplying the virgin material (5), a quantitative feeder (24) for the scrap raw material connected to the second driving motor (31) for supplying the scrap material (6), an accumulation preventing controller (33) connected to a level sensor (25) installed in the hopper (3). The virgin material (5) and the scrap material (6) are independently supplied to the hopper (3), and their accumulation is detected by the level sensor (25)[JPS524096A]
