The research on the sifting from processing of East Donbass refuse heap for manufacturing wall ceramics goods

摘要

The results of the research into sifting of eastern Donbass gob pile processing as raw material for manufacturing wall ceramics, that is popular industrial raw material of the region, are highlighted in the report. It is stated that the main sifting components are siltstones, clay slates, claystone, and sandstones. The main minerals of the sifting are feldspar, crystalline silica, mica, and hydromica. The haracteristic of sifting handling ability for which the most suitable is the way of goods compression molding at elevated pressure and reduced humidity is given. It is stated that the main technology factors are grain composition of raw material mass, its humidity, compression pressure and firing temperature. Variation of technology factors' data makes it possible to get different kinds of products (course, lining, arch brick) with a wide range of features. Methods of evaluation of quality merit rating and the way this rating affects properties of final product are offered. There is high economical perspective of sifting implementation for production of wall ceramics.
