Abstract
Se proporciona un rodillo de molienda para una prensa de rodillos 5 que presenta un cuerpo de rodillo cilindrico (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 mas alla de la superficie envolvente exterior del cuerpo de rodillo (6). Ademas, se preve que la union entre el cuerpo de rodillo (6) y la pared lateral (7) se efectue mediante al menos una conexion de atornillada (9), colindando la pared lateral (7), en el estado no conectado, es decir, cuando la conexion atornillada prevista para la union no ha sido apretada todavia al menos con un par de apriete nominal definido, en una primera seccion (13) con el lado frontal del cuerpo de rodillo (6) y formandose en una segunda seccion (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 deformacion elastica de la pared lateral (7) en el estado conectado, es decir, cuando la conexion atornillada (9) prevista para la union se ha apretado al par de apriete nominal definido. Debido a este diseno del rodillo de molienda, las fuerzas axiales relativamente altas que actuan sobre la pared lateral (7) pueden compensarse con un par de apriete relativamente bajo para la conexion o conexiones atornilladas 9, lo que tiene un efecto positivo sobre la vida util de la union.A grinding roll is provided for a roll press 5 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 that projects 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 screwed 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 forming 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 to say, 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.
