摘要:
A reconditionable high pressure grinding roller stud is provided. The stud is substantially cylindrical and comprises a grinding surface; an attachment end configured to attach to a roller; and a side wall connecting the grinding surface to the attachment end. The side wall comprises a recess extending around a circumference of the side wall. The recess enables easy reconditioning of the stud such that the worn grinding surface can be removed to expose a second grinding surface.

The present invention relates to rollers subjected to wear conditions and surface reinforcements for such rollers. More specifically, the present invention relates to the orientation of projections on the rollers or surface segments of such rollers. In one embodiment, the roller includes a hub. The roller also includes a plurality of removable surface segments attachable to the hub so as to form a layer around the hub. Each surface segment has two opposed sides and an exterior surface. The spacing between projections across the exterior surface decreases from each of the opposed sides to an intermediate point between the opposed sides.

摘要:
A description is given of a wear-resistant roller (1) for processing abrasive materials, such as crude ore, cement raw materials or similar materials, where a roller body (2) is provided with a wear layer comprising a number of elements (3) surrounded by a wear-resistant material (4) suitable for being sintered and fixed to the roller body by means of a sintering process. The roller is characterized in that the elements, which have significantly lower resistance against wear than the surrounding wear-resistant material, are arranged with a space between each other and fixed to the roller body when the surrounding wear-resistant material by means of the sintering process is sintered to the roller body.
