ROLLER PRESSES, IN PARTICULAR FOR CRUSHING STRONGLY ABRASIVE SUBSTANCES. |
摘要 |
The invention relates to a roll press, in particular for processing very abrasive materials, comprising at least two press rolls of which each includes a wear layer arranged on a basic body. The wear layer comprises substantially plane zones of a highly wear-resistant material while the spaces between the highly wear-resistant zones are filled with a material of different wear resistance. Furthermore, the material for the spaces is a composite material which is adapted to be sintered, and the highly wear-resistant zones are formed from hard bodies produced by hot-isostatic pressing. The material for the spaces and the material for the wear-resistant zones are bonded to the basic body in a hot-isostatic pressing process. The wear resistance of the composite material is substantially slightly greater or smaller than the wear resistance of the hard bodies in accordance with a desired profile which will obtained through wear. |
