Patent

CA 2657067

The invention relates to a roller press, particularly for interparticle comminution, having two rollers (10, 11) separated from one another by a roll nip (12), and using hydraulic cylinders for pressing the one roller over the material located in the roll nip against the opposite roller, thus reducing the surface stress of the rollers and increasing the service life. Furthermore, the invention relates to the configuration of both rollers (10, 11 ) as idle rollers that are displaceable transversely to the roll nip (12), the bearing housings (13, 14) of the idle rollers being supported by hydraulic cylinders (15, 16) at side pieces (17, 18) of the machine frame, the hydraulic cylinders being provided to supply the roller pressing force.

Pour créer une presse à rouleaux en particulier pour la fragmentation d'un lit de matériau, avec deux rouleaux (10,11) séparés l'un de l'autre par une fente (12) entre les rouleaux et avec utilisation de cylindres hydrauliques pour presser le premier rouleau sur le matériau se trouvant dans la fente entre les rouleaux, contre le rouleau opposé, où la sollicitation de surface des rouleaux est réduite et leur durée de vie doit être augmentée, il est proposé, conformément à l'invention, de configurer les deux rouleaux (10,11) comme rouleaux fous mobiles transversalement à la fente (12) entre les rouleaux, dont les logements de palier (13,14) sont supportés sur des parties latérales (17,18) du bâti de la machine par l'intermédiaire des cylindres hydrauliques (15,16) appliquant la pression de compression des rouleaux.
