WASTE DISCHARGE EXTRUDER

摘要

A waste discharge extruder 100 is disclosed herein. In a described embodiment, the waste discharge extruder 100 comprises a housing 102 having a waste inlet 110 for receiving waste to be moulded, and a waste discharge outlet 118 for discharging the moulded waste. The waste discharge extruder 100 also comprises an axially rotatable first spiral screw 210 having a first spiral screw breaking section 214 and a first spiral screw extruder section 216, and an axially rotatable second spiral screw 250 arranged adjacent to the first spiral screw 210. The second spiral screw 250 is arranged to rotate in a synchronized manner to the first spiral screw 210, and the second spiral screw 150 includes a second spiral screw breaking section 254 and a second spiral screw extruder section 256. The first spiral screw breaking section's spiral 218 is arranged to cooperate with the second spiral screw breaking section's spiral 258 for fragmenting the received waste, and the first spiral screw extruder section's spiral 218 is arranged to cooperate with the second spiral screw extruder section's spiral 258 to mould the fragmented waste to form discrete volumes of the moulded waste.
