Product is delivered into the decanter’s drum by the mono-pump. Here, as the results of the applied G forces, the 12% solid and 88% liquid contents in the products are being separated from each other in the superb quality. Liquid content is delivered to the decanter’s lower container through rear channel and then, discharged from there out of the system. The solid content is proceeded to the front side of the decanter. From that point, it is taken into the stock tank. Gearbox assembled at the front part of the drum provides the discharge of the solid content out of the system, through creating a certain rotation difference between the drum and the internal spiral. Spiral coils have been plated with the tungsten carbide, hardness of which is 60-65 Rockwell. The reason for this application is to decrease the wearing to the minimum level, which might be occurred in time.
