  • Beschreibung: <jats:p>Plastics are one of the most common materials. Due to its high technical and economical characteristics, this class of materials is used in almost all industries, that is why further growth of the production of plastic products is predicted. Today, the biggest problem in the field of polymer processing by extrusion is to ensure the best possible parameters of resource-energy efficiency of equipment. At the same time, the creating of compounds based on polymers is developing very actively, which requires more flexibility from extrusion lines, since a large number of compositions which differ in their characteristics can be developed on the base of a polymer. The factors listed above have led to cascade extrusion lines become increasingly wide-spread in industry today. Analysis of the extrusion equipment market showed that the schemes with a high-speed double-string extruder at the first stage is more popular. However, the desired mixing quality can be achieved by using a much simpler disc extruder. The article is a review that aims to determine the possibility and feasibility of more efficient arrangement of a cascade scheme for processing composite materials using a disk extruder. Theoretical and experimental studies have shown that melting processes are more efficient in the field of high shear rates at low pressures. Disk extruder is great option for that objective. In this scheme, it is proposed to use a dose feed disk extruder as a homogenizer, and a gear pump as a metering device which allows to reduce pressure and capacity fluctuations before forming device to less than 1%. As a result, it has been determined that the proposed design of the extrusion plant will be more energy efficient than the options on the market and will be able to significantly reduce pressure and performance fluctuations at the inlet to the forming device.</jats:p>
