Rational preparation of waste coal mixture for production of bricks by the method of compression molding

Abstract

Rational preparation of the mixture containing technogenic raw material - waste coal for the production of wall ceramics is developed. It was established that the technology of high-quality ceramic bricks requires: grinding of raw materials to class 0.3 + 0 mm, its aggregation in the intensive mixers into granules 1-3 mm, compression molding of adobe to plastic deformation of granules, drying and firing.
