Scientific novelty
The screw extruder comprises a bearing unit, a feed hopper, a screw chamber housing, a drive, a forming head, and a screw with flights made in the loading and transport zone with the possibility of axial movement. Furthermore, a segmental washer is additionally installed in the extruder, which is rigidly fixed inside the forming part of the nozzle. Segmental holes are made in it, the cross-section of which decreases towards the discharge side, and they are separated by bridges. The segmental washer is made with a cylindrical thickening located on the side of the forming part of the nozzle, in which a sliding bearing is installed; a nozzle is coaxially attached to the discharge end of the housing, consisting of two parts, forming and discharge, which are connected to each other with the possibility of removal; the forming part is made in the form of a truncated cone, and the discharge part is in the form of a cylinder.
Advantages
This design (specifically the original design of the segmental washer) ensures high reliability of the extruder and the ability to process a wide variety of raw materials, including very hard ones, such as various types of minerals.
Commercial implementation
For processing a wide range of raw materials — from agricultural products to minerals, as well as various types of industrial waste.
