Beschreibung
Zusammenfassung:	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.
