| 发明名称 | Process for producing a casing for a roller press | ||
| 摘要 | A process for producing a casing for a roller press for subjecting particulate matter to be ground to high pressure treatment, the casing having a profiling defined by profile comb, wherein the process includes the steps of casting a cylindrical hollow body and introducing axial longitudinal grooves onto the surface of the cylindrical hollow body. The material for casting is of a particular composition, where that composition includes, among other components, between 0.0012% and 0.0027%, by weight, of phosphorus (P). | ||
