Method and apparatus for the treatment of plastic materials |
摘要 |
<p>Expanded or foamed plastic material, such as expanded polystyrene, is fed into a hopper (10) containing an auger (12) which carries blades for cutting the plastic material into pieces and for feeding it into a chamber (19) containing a vertically reciprocable piston (20A) and a horizontally reciprocable piston (21A). The two pistons (20A and 21A) operarte sequentially to effect compression of the plastic material and to feed the compressed material into the entry end of a horizontal chute (22). A hydraulically operated main ram (22A) is movable along the chute (22) to effect additional compression of the plastic material and to displace it along the chute (22) for discharge. <IMAGE></p> |
