Embodiment Construction
[0054] figure 1 The comminution device of the present invention is shown schematically, which comprises two horizontally supported and staggered rollers 1 and 2 arranged one above the other, an integrated breaker 10 and a system consisting of a feed container 3 and a roller feeder 9. Feeding and discharging device. The lower roller 1 corresponds to the figure 1 are driven in the direction of the arrow shown. Roller 2 is arranged vertically offset from roller 1 above driven roller 1 . The upper roller 2 is fed hydropneumatically towards the roller 1 via a lever system 6 by means of a hydraulic cylinder 7 . The upper roller 2 is dragged by the friction of the load surface of the driven roller 1 covered by the material or substance or can have its own drive. The diameter ratio of the lower roller 2 to the upper roller 2 is preferably 1.0 to 2.0 and particularly preferably 1.0 to 1.5.
[0055] The feed and discharge devices are arranged in the region of the apex of the driven...
