ANALYSIS OF THE WORKING PROCESS OF AN ENERGY-EFFICIENT EXTRUDER

Abstract

Autogenous extruders are characterized by the fact that the heat required to affect the processed raw materials is generated directly in the machine path. This principle of operation assumes a relatively simple and reliable design of the extruder, however, it makes it extremely unprofitable from the point of view of energy saving, a technical means. The paper proposes a design and technological scheme of an energy-efficient extruder, in which it is proposed to use an induction heater to heat the processed raw materials. In such an extruder, the performance of individual blocks in comparison with mass-produced machines is evaluated from other positions. Based on the analysis of the design and technological scheme and the structural model of an energy-efficient extruder, recommendations for the design of the main design parameters of individual units, as well as the modes of its workflow, are substantiated.
