APPLICATION OF CENTRIFUGAL IMPACT GRINDERS FOR PROCESSING POLYMER MATERIALS IN RDF FUEL PRODUCTION

Abstract

The article examines the problems of municipal polymer waste disposal in the Republic of Belarus. It is established that, in crushed form, this waste can be used in many industries. A centrifugal impact grinder that can be used for these purposes is proposed. A method for calculating the destruction energy of polymeric materials is presented. The results of experimental studies aimed at determining the applicability of mills of a similar design for polymer waste recycling, as well as identifying their optimal operating modes, are presented. The influence of source material moisture and the occurrence of static electricity on the grinding process are considered. The productivity and specific ener-gy consumption of the grinder under various conditions are assessed. Conclusions are drawn regarding the feasibility of using a centrifugal impact grinder with flexible elements for polymer waste recycling, and recommendations are given for ways to improve this process.
