High-alumina attapulgite volcaniclastic-rock chamotte powder

Abstract

The invention discloses high-alumina attapulgite volcaniclastic-rock chamotte powder. The high-alumina attapulgite volcaniclastic-rock chamotte powder in the technical scheme is mainly characterized by comprising attapulgite clay tailing powder, volcaniclastic rock mixture, high-alumina bauxite, kaolin, coal gangue and bentonite tailings. A finished product of the high-alumina attapulgite volcaniclastic-rock chamotte powder is obtained by uniformly stirring the ingredients, crushing, soaking, extruding, roasting, grinding and packaging. The high-alumina attapulgite volcaniclastic-rock chamotte powder has the advantages of small high-temperature creep, high erosion resistance and good thermal shock resistance. The high-alumina attapulgite volcaniclastic-rock chamotte powder is made of a great quantity of various wastes, so that resource utilization rate is increased beneficially, the wastes turn into wealth, land occupation can be reduced, environmental protection and purification are achieved, energy is saved, and economic benefit is improved. The high-alumina attapulgite volcaniclastic-rock chamotte powder is applicable to construction of linings of shaft furnaces, hot-blast heaters, furnace tops of electric furnaces, blast furnaces, reverberating furnaces and rotary kilns.

Description

technical field [0001] The invention relates to a refractory material, in particular to an attapulgite pyroclastic rock high alumina clinker powder. Background technique [0002] There are many types of refractory materials, and the composition is mainly divided into six categories: soil, stone, sand, ore, powder and other materials, and alumina in high-alumina refractory materials is ≥ 48%. [0003] 80% of my country's mineral resources are associated mines, a large amount of valuable resources are stored in tailings, and tailings stockpiles require a large amount of land. Many tailings ponds have been used beyond the time limit or overloaded, or even operated in violation of regulations, which has caused great safety hazards in the tailings ponds and posed a serious threat to the property and life safety of people in surrounding areas. [0004] In addition to attapulgite, attapulgite clay often contains minerals such as bentonite, kaolinite, hydromica, sepiolite, quartz, ...

AI Technical Summary

Problems solved by technology

[0005]Pyroclastic rocks coexist with attapulgite clay deposits, and pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits, and some attapulgite clay deposits The thickness of the pyroclastic rock layer in the upper layer of the mining area is as high as tens of meters. During the mining process of the attapulgite clay, the pyroclastic rock in the upper layer of the attapulgite clay mining area is discarded as waste. According to field investigations, every ton of attapulgite clay mining Rodstone clay produces more than 30 tons of pyroclastic rocks. Calculated at an annual output of 150,000 tons, the pyroclastic rocks produced are as high as 4.5 million tons. They have not been utilized for many years, and the entire mining area is re-accumulated everywhere. Pyroclastic rock mixture, causing serious waste of resources and economic losses
