A description is given of a method for producing a wear-resistant roller for processing abrasive materials, such as crude ore, by which method a layer of wear-resistant material is provided on at least a part of the surface of the roller (1) where high resistance to wear is needed. The method is characterized in that said layer of wear-resistant material comprises a flexible band (2) being at least partially saturated with wear-resistant particles, where said flexible band (2), without any need for heating, is formed and fitted to the curvature of the surface of the roller (1) for subsequent bonding to the roller (1) by means of a sintering process. In this way it will be relatively easy and fast to manufacture a wear-resistant roller and it will be possible to manufacture rollers with a very large diameter, without being limited by equipment which must be capable of withstanding high pressures. |
