Thin issues products of processing waste heaps as raw materials for ceramic wall products

Abstract

Shown high perspectivity of production of wall ceramics products on the basis of fine-grained gob pile processed products with a high content of coal constituent. The characteristics of these materials, which are actually a ready-made ceramic fusion mixture, as well as the characteristics of the products obtained depending on the roasting temperature, are given. The established relationship between the various properties of the products obtained, the compressive strength of which is from 10 to 19 MPa, at a low density. Recommendations on the main technological parameters of production are given. It is emphasized that low prime cost of products is caused: excluding the costs of raw materials associated with the development and maintenance of fields; practical absence of costs for mass preparation; drying of products due to heat extraction from the furnace; lack of fuel costs necessary for roasting. It is pointed out that in the production of wall ceramics products based on fine-grained waste products of waste heaps, additional sources of income appear that are associated with a reduction in capital and current costs for the maintenance of dumps of FGPPP and the use of excess heat in various directions.
