Knife with a pressure chamber for according to the wolf active principle comminution machines

摘要

The invention relates to a knife with a pressure chamber for according to the wolf active principle comminution machines.The knife as a pressure space which is designated by the circular blade (1, 2) is designed in such a way that in the well-known (3) a supporting system (4) for receiving the clamping forces for the guarantee of the cutting conditions of the tools by the clamping nut, a support surface (5) for the blade (1) in front of the preliminary cutter (6), and a defined space (7) to the working worm (8), in an end position with a spacer (4) are present for the working worm.The operating principle of the mechanical of raw material transferred from the last worm gear to the cutting unit is implemented by means of a pressure storage chamber (7), that is to say a spatial distance between the screw and cutting set replaced.The from of the working worm (8) supplied amount of raw material used comprises so generated in connection with the material be compressed conveying process, the volume decrease in the screw volutions and the rotating pulse bursts of the or of the last the auger flight (9) a compression of the raw material and thus a pressure cushion.The pressure space and ensures a new service feature of the raw material processing by means of a complete utilization of all of the bores of the perforated disk in the form of a chopping tool with a 20 to 30% higher processing power at about 25% lower energy requirement and simultaneous improvement in quality of the end product.
