Attapulgite volcaniclastic rock siliceous chamotte powder

Abstract

The invention discloses an attapulgite volcaniclastic rock siliceous chamotte powder. The technical scheme is characterized in that the attapulgite volcaniclastic rock siliceous chamotte powder is composed of attapulgite clay tailings, volcaniclastic rock mixtures, quartz rocks, waste silica bricks, opals, coal gangues and bentonite tailings. Materials of the attapulgite volcaniclastic rock siliceous chamotte powder are subjected to uniformly stirring, smashing, soaking, extruding, calcination and grinding, and then the materials are packaged to form a finished product of the attapulgite volcaniclastic rock siliceous chamotte powder. The attapulgite volcaniclastic rock siliceous chamotte powder has the advantages that the resistance to acid slag is high, the thermal shock stability is good and the refractoriness is high. According to the attapulgite volcaniclastic rock siliceous chamotte powder, a large number of various wastes are utilized in the materials of the attapulgite volcaniclastic rock siliceous chamotte powder, the resource utilization rate is increased, waste materials are changed into valuable things, the occupied land is reduced, the environment is protected and purified, the energy is saved, the production cost is lowered, the economic benefits are improved, and the attapulgite volcaniclastic rock siliceous chamotte powder is suitable for acid refractory concrete constructions.

Description

technical field [0001] The invention relates to a refractory material, in particular to an attapulgite pyroclastic rock siliceous clinker powder. Background technique [0002] Refractory materials are mainly made of natural ores such as bauxite, silica, magnesite, and dolomite after processing. [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, opal and carbonate. [0005] Pyroclastic rocks coexist with attapulgite clay deposits. Pyroclastic...

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 pyroclastic rock deposits in the upper layer of attapulgite clay deposits of The thickness is as high as tens of meters. During the mining process of attapulgite clay, the pyroclastic rock in the upper layer of the attapulgite clay mining area is discarded as waste. There are more than 50 tons of pyroclastic rocks. Calculated according to the annual output of 150,000 tons, the pyroclastic rocks produced are as high as 7.5 million tons, which have not been utilized for many years. The entire mining area is full of re-accumulated pyroclastic rock mixtures, causing severe waste of resources and economic loss
