Abstract (en)
[origin: EP0388631A2] 2.1 In order to prevent blocking of the transportation of material to the centrifuge drum, a constant difference in speed of revolution between drum and worm is required, which is relatively small but independent of loading. It is costly and complicated to achieve a slip-free drive using a planetary gear system. The new drive is intended to avoid this cost and to simplify the device. 2.2 In order to achieve a load-independent, constant difference in speed of revolution between the drum and worm, drive discs constructed as toothed discs are arranged on their drive shafts, said drive discs being form-fittingly connected via continuous toothed belts to further toothed discs arranged on the shaft of a drive motor. 2.3 Separation of solid/liquid mixtures. <IMAGE>
