Abstract

Se proporciona un rodillo de molienda para una prensa de rodillos que presenta un cuerpo de rodillo cilíndrico (6) y al menos una pared lateral (7) dispuesta en un lado frontal del cuerpo de rodillo (6) y unida con el cuerpo de rodillo (6) de manera resistente al giro que se proyecta exteriormente más allá de la superficie envolvente exterior del cuerpo de rodillo (6). Además, se prevé que la unión entre el cuerpo de rodillo (6) y la pared lateral (7) se efectúe mediante al menos una conexión de atornillada (9), colindando la pared lateral (7), en el estado no conectado, es decir, cuando la conexión atornillada prevista para la unión no ha sido apretada todavía al menos con un par de apriete nominal definido, en una primera sección (13) con el lado frontal del cuerpo de rodillo (6) y formándose en una segunda sección (14) un intersticio (18) entre la pared lateral y el lado frontal del cuerpo de rodillo. Este intersticio (18), por el contrario, se elimina al menos parcialmente, preferentemente por completo, como resultado de una deformación elástica de la pared lateral (7) en el estado conectado, es decir, cuando la conexión atornillada (9) prevista para la unión se ha apretado al par de apriete nominal definido. Debido a este diseño del rodillo de molienda, las fuerzas axiales relativamente altas que actúan sobre la pared lateral (7) pueden compensarse con un par de apriete relativamente bajo para la conexión o conexiones atornilladas 9, lo que tiene un efecto positivo sobre la vida útil de la unión.A grinding roll is provided for a roll press having a cylindrical roll body (6) and at least one side wall (7) arranged on a front side of the roll body (6) and attached to the roll body ( 6) in a manner resistant to rotation projecting outwardly beyond the outer wrapping surface of the roller body (6). Furthermore, it is envisaged that the connection between the roller body (6) and the side wall (7) is made by means of at least one screw connection (9), the side wall (7) adjoining, in the unconnected state, is that is, when the bolted connection provided for the joint has not yet been tightened with at least a defined nominal tightening torque, in a first section (13) with the front side of the roller body (6) and being formed in a second section ( 14) a gap (18) between the side wall and the front side of the roller body. This gap (18), on the contrary, is eliminated at least partially, preferably completely, as a result of an elastic deformation of the side wall (7) in the connected state, that is, when the screwed connection (9) provided for the joint has been tightened to the defined nominal torque. Due to this design of the grinding roll, the relatively high axial forces acting on the side wall (7) can be compensated with a relatively low torque for the bolted connection (s) 9, which has a positive effect on the service life. of the Union.
