Abstract
A roller press comprising a drivable pair of rollers with a defined nip between these, one or more stuffing screws, associated with the nip, for feeding the material to be granulated to the nip, and a plate, movable in the direction of the screw axis, on which plate the screw and drive are fixed and a pin which can be brought up against a stationary load cell is held.
Claims4
In a roller press for the production of granules or moldings from a pourable material, which roller press comprises a machine bed supporting a drivable pair of rollers which forms a defined nip and one or more stuffing screws positioned for feeding the material to be compressed to the nip, said stuffing screws having drive means connected to rotate the screws, the improvement comprising:
- a movable plate which is movable with respect to the machine bed in the direction of the screw axis, said stuffing screw and drive means being mounted on said movable plate whereby the reaction force of the material fed to said nip will tend to urge said stuffing screw and said movable plate in said direction, a pin adjustably mounted on said plate for movement in the same direction by means of a setting screw, and a stationary load cell fixed to said bed, said load cell being contactable by said pin whereby a force related to said reaction force is exerted by said pin against said load cell.
