In order to press with the extruder without interruption, the screw conveyor press is equipped with a metering device. This loads the press depending on the material consumption. This enables a pressing process without interruption.
The main advantage of this system is that, by using the dosing device, the material in the rod is more homogeneous and thus the quality of the product is increased. The operator loads a package with a weight of approx. 25 - 30 kg, confirms the task and the automatic process begins. This filling operation can be carried out during the pressing and the extruder does not have to be stopped. An accurate dosage is realised with an automated scale and a warning device reports a minimum level.
