Jaw crushers are used to pre-crush rocks and ore in harsh mining site conditions. The customer was looking to replace their traditional metal plate belt cover. The goal was to design a belt cover that is light enough for a single maintenance technician to remove and replace it in the field. At the same time, the part had to be able to withstand impacts from the rocks, vibration from the machinery, and extreme weather varying from the hot Indian sun to the freezing temperatures of the North. The color, of course, had to be recognizable as Metso’s trademark beige. The part is almost 2.5 meters long and made from 8 mm thick sheet by vacuum molding. The sheets are made using one of Lokari’s three extrusion lines. Lokari produces about a dozen different covers and casings for the customer’s rock crushers and separators in Finland and the Far East.
