Abstract
The aim of the invention is to simplify and to improve mounting of roller bearings in double roller machines, for example, roller presses for interparticle comminution of granular goods. The rollers and the bearing housing thereof are formed by means of slanting rollers and/or thermal roller longitudinal changes. The rollers are guided in a secure manner on the slide guides thereof. The invention is characterized in that the fixed bearing housing and the moveable bearing housing are connected together via a guide rod in each roller.
Claims10
A twin-roller machine for the pressure treatment of granular material, comprising:
- two rollers mounted in a machine frame to rotate about approximately parallel axes which define an axial direction, arranged to be oppositely driven and separated from each other by a roller nip;
- at least one of the rollers mounted as a laterally movable roller;
- bearing housings located at each end of each of the two rollers, the bearing housings for the movable roller being supported on frame side parts by hydraulic cylinders for movement transverse to the axes and being mounted with their undersides on level slideways of machine brackets, one of the bearing housings for each roller having a rolling bearing fixed in the axial direction and the other bearing housing for each roller having a rolling bearing which is movable in the axial direction allowing axial movement of that roller;
- wherein for each roller, the axially fixed bearing housing and the movable bearing housing allowing axial movement are connected to each other by a guide rod.
