<p>A drum granulator (10) is described in which at least a part of the cylindrical outerwall is resilient.This can be achieved, for example, by forming the drum from steel and fitting it with a resilient rubber lining, which is exposed in way of circumferentially extending slots in the steel. The drum rotates past piv- otted rollers which are allowed to descend abruptly onto the resilient part of the wall, dislodging any material which adhered to it.</p> |
