Problems solved by technology

However, due to the relatively narrow application of these products, the market sales volume is not large, and a large amount of polishing waste has not been digested; the third is used as a small amount of raw materials for other ceramic tiles sintered at low temperature, such as antimony and vanadium slag black porcelain Bricks, etc., but also because the market sales of these products are not large, they cannot digest waste residues in large quantities

Abstract

The invention discloses a method for treating solid waste slags in the production process of ceramic tiles. The method comprises the following steps: mixing the solid waste slag produced in the production process of ceramic tiles with powder to be taken as the green brick material, and performing ball milling, pulping, powder injection, moulding, biscuit firing, glazing, glaze firing and edge polishing to obtain the finished products of the ceramic tiles; the solid waste slag accounts for 14-60% of the total weight of the green brick material, and the powder accounts for 40-86% of the total weight of the green brick material; the solid waste slag is formed by waste mud, waste green bricks, polishing waste slag, edging waste slag, scraped waste slag and finely-edging waste slag; the powderis prepared from kaolin, white mud, tea mountain sand, talc and feldspar. The method disclosed by the invention has the beneficial effects that the ceramic tiles are prepared by utilizing the solid waste slag in the production process of the ceramic tiles, and processes of low-temperature biscuit firing and high-temperature glaze firing are adopted; secondary pollution caused by landfill of the waste slag is reduced, the problem of difficulty in treatment of the solid waste slag in manufacturers of the ceramic tiles is solved, the production cost is saved and the economic benefit and the social benefit are good.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a method for treating solid waste residue in the production process of ceramic tiles. Background technique [0002] The production of traditional ceramic tiles consumes a lot of energy and non-renewable mineral resources such as clay, feldspar, and quartz. In the production process, a large amount of solid waste will be produced. For example, during the processing of ceramic tile raw materials, the scattering of raw materials, slurry scattering, ball washing, flushing of the ground, etc., the solid waste produced will flow into the sewage pool with the sewage and form sludge after sedimentation; the scattering of powder materials will produce waste powder. ;Waste body and waste powder will be produced during molding; waste body will be produced when drying; waste body and waste ceramic tile will be produced during firing; , chamfering, etc. will produce waste tiles, ...
