Method for producing fly ash haydite

Abstract

The invention relates to a method for preparing a fly ash porcelain granule, which comprises materials and proportions thereof and a production technical process, wherein according to the material proportions, 85 to 95 percent of fly ash, 1 to 10 percent of coal dust and 0 to 10 percent of clay are prepared into 1 to 2 percent of 0.5 to 0.05 percent combustion improver solution; the technical process comprises the following steps: stirring the materials to prepare a mixture; spraying a combustion improver solution to the mixture; rolling the mixture to prepare a porcelain granule ball blank; screening the blank and roasting the blank in a kiln for 1.0 to 1.5 hours; cooling the blank until the temperature is 600 DEG C and then taking the blank out of the kiln; and cooling the blank naturally to obtain the finished product of the fly ash porcelain granule. Because the mixture is doped with a small amount of the coal dust and the combustion improver solution agglutinates the mixture to form the porcelain granule ball blank, all inflammable components contained in the porcelain granule ball blank can be burnt sufficiently, is not only advantageous to improve the burning efficiency, reduce the cost, shorten the roasting time and improve the production efficiency, but also overcomes the situations that in the prior art, the fly ash porcelain granule has different colors and different hardness degrees, thereby providing a basic guarantee for the fly ash porcelain granule to be used in building decorative materials.

Description

technical field [0001] The invention relates to the technical field of building material manufacturing, in particular to a method for manufacturing fly ash ceramsite. Background technique [0002] Fly ash is a large amount of waste discharged by large coal users such as thermal power plants. Large and small thermal power plants and other coal-consuming enterprises all over the country produce a large amount of fly ash every year. Because there was no treatment and utilization of it before As a result, it has become a product that pollutes the environment, causing serious harm to the living environment of human beings, and also causing a heavy burden to enterprises. How to turn fly ash into treasure and make secondary use to reduce the burden on enterprises and reduce the degree of environmental pollution caused by fly ash is a major event that benefits the country and the people. It has attracted the attention and attention of the whole society. Some effective technical sol...
