<p>A description is given of a roller mill for grinding particulate material such as cement raw materials, cement clinker and similar materials, said roller mill comprising a grinding table (1) which by means of a drive mechanism (2) is rotatable about a vertical axis (3), at least one roller (4) which is rotatably mounted on a shaft (5) and being maintained in tangential direction relative to the grinding table by means of a guide mechanism (6) and a support (7). The roller mill is peculiar in that it comprises a vibration-compensating device (8) which is arranged in connection with the guide mechanism (6) to ensure in interaction therewith that the roller (4) is maintained in tangential direction relative to the grinding table (1), independently of the flexibility of the guide mechanism support (7) so that the variations in the torsional moment of the mill drive mechanism (2) and hence the wear on the drive mechanism are reduced. This is due to the fact that the vibration-compensation mechanism equalizes the elastic movement affecting the guide mechanism support when the tangential force, which is to be absorbed via the guide mechanism (6), varies due to a change in the operating environment, thereby actively preventing the roller (4) from moving tangentially relative to the grinding table (1).</p> |
