Extruding wood chipboard - using intermittently acting ram thrusting charge into first consolidating passage entrance while closing off inlet

摘要

Vegetable particles plus binder are extruded, using an axial ram which moves through area beneath a top inlet, and passing the material through a curving passage insulated from that area. The ram stroke moves it into the passage beyond the inlet area and the ram is long enough to close off the inlet during its stroke. Process is suitable for extruded chipboard, it orientates the particles as required, to provide homogeneous prod.
