Technical field
The present invention relates to the production technical fields of Ceramic Tiles, and in particular to a kind of to be produced using capital construction tailing, mill tailings
The method of energy-saving environment-friendly ceramic brick.
Background technology
In recent years, under the promotion in urbanization acceleration, fitting-up demand to factors such as high-end development, the production of China's Ceramic Tiles
Amount continues to lift up on higher radix.By the number that guangdong ceramic association counts, 2010-2016, China's Ceramic Tiles yield is not
Disconnected to improve, yield rises to 102.6 hundred million square metres from 75.8 hundred million square metres between short 6 years.In recent years, ceramic mineral raw material mistake
Exploitation is crossed, in addition environmental protection is attacked severely, many mines are hollowed out or forbid exploiting, and high aluminium content, the high-quality sand of high whiteness and former mud are more next
It is fewer.Ceramic Tiles often only choose most pure, most high-grade raw material in terms of choosing raw material, and the high low grade of impurity content is former
Material does not have to as tailing waste, or even causes the significant wastage of ceramic raw material, and tailing is accumulated together as landfill soil with table soil
Great pollution is also resulted in environment an urgent demand.This just china clay resource can not carry out comprehensive development and utilization again to valuable,
The utilization rate for improving ceramic raw material resource, to economize on resources.To ensure that ceramic brick product flexural strength and green strength are sufficiently large,
It is readily produced control, this requires ceramic tile blanks to be formulated in chemical analysis, and between 18%-21%, mud material contains alumina content
Amount is 20% or so.When being formulated Central Plains mud too high levels, formula components difficulty aoxidizes in sintering process, will lead to the yield of product
The problems such as low, high energy consumption, substantially increase the production cost of Ceramic Tiles.The more regional mine tailings in riverhead are more, and mill tailings is a kind of
Mining surface layer mud skin or exploitation post-processing tailing, impurity is more, and chemical component fluctuation is big, its yield reaches annual more than ten
Ten thousand tons, discarded or be used for filling out mud hole；Building tailing is that a kind of Scenic Spot Development or construction site sort out the koppie sand come,
Its appearance color is soil Red, mud base intensity height is made, long-distance is short, and price is relatively inexpensive, and aluminium content is high.
