The PELERIN® extruder type 750 RR is equipped with a cylindrical outlet auger (like the auger located in the tank bottom), with a 730-mm diameter. The mixer, which (when added to the extruder) constitutes the extrusion set, has also been re-examined: the diameter of its outlet auger has been brought up to 550 mm to ensure clay feeding flow matching the extruder’s capacity (100 t/h maximum flow rate). The unit is equipped with a vacuum chamber that is larger that of the former model, type 650 ER. This enables a 37% increase of the attendance time within the vacuum chamber to ensure more efficient de-airing of the clay body, which is a key stage during clay preparation because it ensures the final quality of the products.
