Roller presses are used for pressing or briquetting various types of coal, minerals, ores and mixtures with binders. In order to achieve sufficient breaking strength by pressing or briquetting, products with low surface moisture are suitable for handling. Depending on the input material and the final product, roller presses can be equipped with optional functions. The material fed into the screw is a mixture of gypsum hemihydrate and gypsum dihydrate. The arrow screw lifts the material and pushes it into the area between the two rollers. Briquettes are created by pressing the material in the gap between the cylinders. A certain part of the material leaves the press through the gaps of the trough forms. The subsequent screening process is performed with a 10 mm cut. Adapting the press to the overall system as part of the trial run is extremely important to deliver a product that meets quality requirements. Interruption of the briquetting process due to a lack of material leads to disruption of the material flow as well as excessive stress on the roller press. The technical description of control and regulation of the roller press, including accessories, is part of the specification of the independent energy and control system supplier.
