ROLL, METHOD OF PRODUCING A ROLL AS WELL AS MATERIAL BED ROLL MILL

摘要

In this roll, which is intended in particular for the comminution of brittle materials for grinding in a material bed roll mill, a profiled cladding for protection against wear is constructed according to the invention on the outer face of a circumferential casing region by machining profile grooves into the material of the circumferential casing region for particles of material to be firmly pressed in and only applying hard material strips by build-up welding onto the profile projections delimiting the profile grooves. This roll made up according to the invention causes a relatively low consumption of hard material with durable protection against wear of its surface and a reliable capacity for drawing in material.
