<p>The disclosure relates to a ram extruder (10) including an extruder barrel (11) havingan extrusion die (14) atone end and a hydraulic ram (20) at the other end having a piston (22) which is advanced along the barrel by the ram to displace material in the barrel through the extrusion die. To facilitate loading of the barrel a loading port (24) is provided in the side of the barrel adjacent said other end of the barrel through which the barrel may be charged after retraction of the piston following an extrusion operation and a port closure device (25, 26, 27, 28) is provided to close the port after extrusion and evacuate air from the barrel prior to advancing the piston (22) past the port to minimise the air contained in the barrel prior to the extrusion operation.</p> |
