An option to modernize the worm of the strand extrusion machine is proposed. The technical solution of this worm of the string extrusion machine is the improvement of the mixing section of the extruder worm, which is located in the gap of the screw line in the homogenization zone of the extruder. This design of the mixing section of the worm of the strand extrusion machine allows to intensify the process of dispersion of agglomerates and mixing of the dispersed phase in the dispersed medium and as a result to obtain a homogeneous structure of the polymer, which in turn allows to improve the quality of the final product.

Electrostatic precipitators are designed for highly efficient cleaning of process gases and aspiration air from solid or liquid particles released during technological processes in various industries. To improve the design of the plate electrostatic precipitator and eliminate its lack of insufficient intensity of shaking of the electrostatic precipitator plates, a design of the system for cleaning electrodes of the electrostatic precipitator based on the prototype was chosen, which provides multilevel shaking (top, bottom, side of the plates) in the process of continuous operation of the plate electrostatic precipitator and increases the intensity of shaking dust from the plates of the electrostatic precipitator.
