Abstract

A pellet press (1) is equipped with a control device by means of which it is possible to maintain a desired degree of pressing roller slip, for example none, or a presettable maximum value. <??>For this purpose, the pellet press (1) has a first measuring device (27, 28) for measuring the circumferential speed of the perforated die (8) and a second measuring device (23, 24) for measuring the circumferential speed of the pressing rollers (11, 12). The two circumferential speeds are compared in a comparison device (30, 31) and when a preselectable maximum value for the difference of the two measured values is exceeded, a slip signal is generated by means of which the press drive and/or the feeding of starting material to be pressed is influenced in such a way that the slip is suppressed. <IMAGE>
