| 摘要 |
A description is given of a wear-resistant roller for processing abrasive materials, such as crude ore, cement raw materials or similar materials, where a roller body is provided with a wear layer comprising a number of elements surrounded by a wear-resistant material 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. |
