Abstract: A roller for a roller press has a core formed with axially opposite outer ends, an axially central passage, and axially spaced and radially extending inlet and outlet passages extending radially at the outer ends from the central passage and opening radially outward at an outer surface of the core. A coolable jacket surrounds the core, and respective manifold rings are mounted on outer ends of the core, cover inlet and outlet passages at the end faces of the jacket. Respective L-shaped connecting passages each have an axially extending segment opening into a respective one of the cooling passages of the jacket and a radially extending segment opening into the respective groove.

Abstract: The invention relates to a press roller for a roller press, in particular for briquetting, compacting or grinding granular material, having a roller core (1) and a roller sleeve fastened to the exterior of the roller core (1), said sleeve being composed of a plurality of segments (2), distributed over the circumference, with mutually facing lateral faces (3). The segments (2) have clamping shoulders (5) which extend around the front faces, the segments (2) being releasably fastened at each front face to the roller core (1) by means of at least one fastening ring (6). Said fastening ring fits over the clamping shoulders (5) of the segments (2). The fastening ring (6) is or can be clamped against the segments (2) by means of axially parallel clamping bolts (7). Each segment has at least one axially parallel opening for the clamping bolts which, relative to the extension in the circumferential direction, is arranged between the two lateral faces (3) of the segment (2).

Abstract: The invention relates to a press roller for a roller press, in particular for briquetting, compacting or grinding granular material, having a roller core (1) and a coolable casing (2) fastened to the roller core (1), wherein a plurality of cooling ducts (6), which are distributed over the circumference and extend in an axially parallel manner, are arranged in the casing (2) beneath the casing surface, said cooling ducts (6) being connected to an axial central duct (8) in the roller core (1) via radially extending inlet and outlet ducts (7), wherein at least two distributor rings (10) that are each connected at their ends to the casing (2) are arranged on the roller core (1), annular ducts (11) that extend in the circumferential direction being arranged in said distributor rings (10), said annular ducts (11) being connected at one end to the radial inlet and outlet ducts (7) and at the other end to the axially parallel cooling ducts (6).

Abstract: A roller press, in particular for processing highly abrasive materials, includes at least two press rollers, each of which is provided with a wear protection layer arranged on a base body. The wear protection layer includes plate-shaped and pin-shaped wear resistant material elements. The plate-shaped, wear resistant material elements are applied to surfaces of two opposed edge areas of each base body by sintering with or without pressure, preferably by a hot isostatic pressing operation. The pin-shaped wear resistant material elements are arranged in a central section of each base body extending between the edge areas. A method of producing a wear protection layer, in particular for a press roller, is also provided.
