Method for grinding particulate material in a roller press and apparatus for carrying
out the method |
(57) In order to improve the operation of a roller press, a method is described according
to which water is added to the material to be ground.
By this method it is obtained that the material bed formation is improved and that
the vibration level of the roller press is reduced, thus making it possible to increase
the roller speed and hence the utilization of the roller press capacity.
