Electric pulse method of processing cullet

Abstract

The article considers the issue of obtaining a recycling resource during the processing cullet, which harms the environment. During the preparation of raw materials in the household waste recycling stages, the material is crushed to the right size. This is implemented in mills based on various methods of destruction. In this regard, analyses of the currently existing types of mechanical mills were carried out and their disadvantages were investigated. To solve glass recycling problem, this study presents the results of processing cullet by the electric pulse method. We provide a description of operation principle of the experimental setup and the design of the working chamber for processing the material under study. In this technology, the processing cullet is carried out with an increase in the discharge voltage of the storage from 25 kV to 35 kV, the capacitor capacity from 0,25µF to 1 µF, the number of pulse discharges from 100 to 600. By using the electric pulse method particles cullet with an initial fraction of 2 mm and 5 mm were crushed from 1 mm to 0.1 mm. The dependence of the output of the final product on the electrical parameters of the installation and the diameter of the obtained glass powder were received. The results of the grinding raw materials with the formation of pulsed electric discharges in a liquid medium allowed assessing the degree of grinding of the material. According to the obtained research data, optimal parameters of cullet grinding were established.
