dc.description.abstractUntil now, the general construction of the plasticizing system has assumed placing the screw in a fixed barrel. However, at the end of the 20th century, a completely new concept of the design of an extruder was put forward, which had never been used before in the industry or in experimental machines. This new solution consisted in kinematic activation of the barrel itself, which meant it could rotate in the direction identical or opposite to the direction of screw rotation. So far, several design solutions concerning kinematic activation of the barrel of the plasticizing system have been proposed. The idea of this solution is presented in the picture. As a result of the implementation of the international NEWEX project within H2020-MSCA-RISE several new construction concepts were developed for which CAD models were created using the SolidWorks programme. All CAD models were made in such a way that they could constitute the modification of W-25 single-screw extruder, and all of them present a classic or modified screw placed in the barrel plasticizing system, therefore screw diameter D equals 25 mm. The joint length of rotational barrel elements equals 4D. The main reason for using such constructional solutions is the intensification of the mixing process and the increase of homogenization of the processed polymer, filled polymer or a composite. The strength and thermal calculations of selected models were carried out and computer simulations were performed concerning the optimization of the adopted solutions. The most important aim is to maximize the mixing, quantified here by WATS, with little changes in the remaining criteria, i.e., output, melt temperature at die exit (Tmelt), mechanical power consumption (Power), length of the screw required for melting (Lmelting) and viscous dissipationen
