Features of the preparation of calcium-containing raw materials in the production of ceramic bricks

Abstract

The paper considers possibility of using low-melting loam, drilling waste and ash and slag waste of thermal power plants in the production of wall ceramics by the method of semi-dry pressing. The physicochemical processes occurring upon receipt of ceramic materials using production waste at the firing stage are studied. It has been established that an increase in the duration of grinding of calcium-containing raw materials at the stage of preparation of the starting materials determines a change in its particle size distribution, an improvement in the plasticity of the molding materials and an increase in the coherence of the raw product and provides an increase in the mechanical strength of the raw product in comparison with the initial indicators.
