Abstract (en)

A press for dry-pressing granular or powdery ceramic materials which includes a structure, a beam, a hydraulic actuation means for pushing the beam toward a lower mold, a pump for feeding the liquid, hydraulic actuation means, and a motor for actuating the pump. A ratio of inertia between a tonnage of said press and the moment of inertia of the motor is higher than 3500 t/kg m<2>, preferably higher than 5000 t/kg m<2>, more preferably higher than 6000 t/kg m<2>. The apparatus includes a grinding section, an atomizer, a press as described above, and a kiln for firing the pressed material. The method comprises a step in which the speed of the motor is slowed within the pressing cycle, when pressing is not performed. <IMAGE>
