The Natreb Roller Mills, also called laminators or crushers, have wide application in the production of fines. It is efficient with both dry and wet materials. It can be used in the processing of mineral and vegetable coal, clay, feldspar, clays, bauxites, limestone, graphite, graphite, alloy irons, among other materials both in Mining and in the Recycling, Chemical and Fertilizer Industry. Its function is based on the crushing of materials between its two high-strength cylinders, which can be developed in different steel alloys, depending on the application. Its production capacity is related to its size (model) and the regulation of the gap between the rollers.
