Optimization Of The Automatic Operation Of The Plastic Crushing Machine, Yokubjon E. Kurbonov, Madaminjon K. Mahkamov, Nodirbek Sh. Kimsanboyev

Scientific Bulletin. Physical and Mathematical Research

The main costs in the production of plastic products that affect the cost of the product is the cost of materials. It accounts from 70% to 77% of all expenses. For this reason, the processing of plastic products and their use as secondary raw materials reduces the cost of production and leads to increased economic efficiency.

In order to obtain high-quality secondary raw materials by crushing plastic products, it is necessary to divide them into types before crushing. For classification and identification of plastic products, a fluorescent material is used to determine the composition and concentration of plastic. The result …
