Patent Number: 8,820,668

Title: Roller press, particularly for interparticle comminution

Abstract: In order to create a roller press, particularly for comminuting a bed of material, the roller press having two rollers separated from each other by a roller nip and using hydraulic cylinders to press the one roller against the oppositely situated roller over the material situated in the roller nip, the stress on the surface of the rollers to be reduced and their service life to be increased, it is proposed according to the invention that both rollers are designed as loose rollers that are displaceable transversely relative to the roller nip, the bearing housings of the rollers being supported on side parts of the machine frame by hydraulic cylinders that apply the roller compaction pressure.
