TWIN-ROLL MACHINE, IN PARTICULAR FOR COMMINUTING A BED OF MATERIAL

摘要

A two-roll machine has two rolls rotatably mounted in bearing housings, driven in opposite directions and separated from each other by a roll gap. One roll is a loose roll with bearing housings horizontally supported on machine frame side parts by hydraulic cylinders applying a roll pressing force. The other roll is a fixed roll with bearing housings horizontally supported on frame end pieces. The bearing housings are mounted on sliding tracks of two lower-flange and two upper-flange machine brackets. The two-roll machine includes a lower frame adjacent to the fixed roll, the lower frame lengthening the two lower-flange machine brackets. A transverse frame is connected to the two upper-flange machine brackets, the transverse frame having a clear opening width which permits the rolls to be moved through the transverse frame onto the lower frame. The frame end pieces are releasably connected to the lower-flange and upper-flange machine brackets.
