Abstract

The invention relates to a method for improving wear and tear on support bodies (54) for plates or grinding belts in large-scale grinders (1). The support body (54) has a base body (18), onto which an abrasion-resistant primary layer of at least 0.3 mm thickness is applied using a thermal spraying process. This is configured as an inhomogeneous layer with an oxide entrapment of a specific porosity. If the support body (54) is a roll for the forward feed unit (20, 28), the roll body is roughened and a primer and the primary layer are applied using a thermal spraying process. Approximately 50 % of the primary layer consists of chromium steel, in particular 13 % chromium steel and an abrasion-resistant hard material and said primary layer provides a coarse surface with good grip that is resistant to wear and tear. If the support body (54) is a grinding-belt contact roll (9, 9'), the latter is polished after the thermal spraying process. If the support body (54) is a grinding belt shoe (50), the base body (18) is roughened and an adhesive layer and then the primary layer are applied in a thermal spraying process. The wear-resistant primary layer is polished to create a smooth surface and the layer construction is configured to produce a high degree of slip.
