Problems solved by technology

At present, it has been widely used in house construction; however, due to the limitation of raw material sources, ceramsite has only used shale to make ceramsite products. The amount is strictly limited, and the amount added directly affects the strength of the board; thus restricting the production and application of this type of lightweight wall material

Embodiment 1

[0037] The clayey shale is collected by conventional methods, and crushed by conventional coarse powder and fine powder crushing machines. After crushing for 2 to 5 minutes, continue the following steps:

[0038] 1) Screen out shale powder with a particle size of 200-280 mesh;

[0039] 2) Take 90 parts of shale powder screened in step 1), 5 parts of fly ash, 1 part of additive mixed with ore washing sludge, boron mud, and sodium nitrate waste residue in a ratio of 1:1, and 4 parts of water and mix evenly Then put it into the mixer and stir it into a mixture; the stirring time is 3 to 5 minutes;

[0040] 3) Unload the mixture described in step 2) from the mixer, put it into the ball making machine, and unload it after making raw meal pellets with a particle size of Φ3-24mm after 3 minutes;

[0041] 4) The raw meal pellets unloaded in step 3) are directly put into a multi-cylinder rotary kiln. The multi-cylinder rotary kiln is composed of 4 kilns with different diameters connec...

Embodiment 2

[0044] The clayey shale is collected by conventional methods, crushed by conventional coarse powder and fine powder crushing machines, and after crushing for 2 to 5 minutes, the following steps are carried out:

[0045] 1) Screen out shale powder with a particle size of 200-280 mesh;

[0046] 2) Take 75 parts of shale powder screened in step 1), 10 parts of fly ash, 16 parts of additives mixed with boron mud and sodium nitrate waste residue in a ratio of 1:1, and 9 parts of water, mix them evenly and put them into the mixer , stirred into a mixture; the stirring time is 3 to 5 minutes;

[0047] 3) Unload the mixture described in step 2) from the mixer, put it into the ball making machine, and unload it after 5 minutes to make raw meal pellets with a particle size of Φ3-24mm;

[0048] 4) The raw meal pellets unloaded in step 3) are directly put into a multi-cylinder rotary kiln. The multi-cylinder rotary kiln is composed of 4 kilns with different diameters connected to each ot...

Embodiment 3

[0051] The clayey shale is collected by conventional methods, crushed by conventional coarse powder and fine powder crushing machines, and after crushing for 2 to 5 minutes, the following steps are carried out:

[0052] 1) Screen out shale powder with a particle size of 200-280 mesh;

[0053] 2) Take 45 parts of shale powder screened in step 1), 30 parts of fly ash, 10 parts of additives mixed with sodium nitrate waste residue, iron dioxide waste residue and ore washing sludge in a ratio of 1:1:1, water After 15 parts are mixed evenly, put them into the mixer and stir them into a mixture; the stirring time is 3 minutes;

[0054] 3) Unload the mixture described in step 2) from the mixer, put it into the ball making machine, and unload it after making raw meal pellets with a particle size of Φ3-24mm after 4 minutes;

[0055] 4) The raw meal pellets unloaded in step 3) are directly put into a multi-cylinder rotary kiln. The multi-cylinder rotary kiln is composed of 4 kilns with ...

Abstract

The invention discloses a light-weight aggregate shale ceramic particle and a production method thereof, which includes powdered argillaceous shale, pulverized fuel ash, additive and water; the ratio of the ingredients is that: 15-90 parts of powdered argillaceous shale, 5-60 parts of pulverized fuel ash, 1-12 parts of additive and 4-15 parts of water. The production method includes the conventional collection of argillaceous shale and the crashing process, besides, the invention also comprises the following steps: (1)screening; (2) the mixing materials is prepared; (3) the mixing material is added into a marble machine so as to produce raw meal pellets and is discharged; (4) the raw meal pellets are fed into a multi-cylinder rotary kiln for drying and sintering and finally the shale ceramic particles are formed; (5) the products of shale ceramic particles, ceramic sand and ceramic block can be obtained after the cooling and the sizing screening process by a trommel screen. The product is sintered in a multi-cylinder rotary kiln at temperature of 1150-1200 DEG C and the material property is changed and is sound-insulating, light in weight, shock-resistant, weather-resistant, and corrosion-resistant, has distinct energy-saving effect and is beneficial to generalization and implementation.

Description

technical field [0001] The invention relates to a ceramsite product and a production method thereof, in particular to a light aggregate shale ceramsite and a production method thereof, belonging to the field of new lightweight materials for building construction. Background technique [0002] In recent years, in order to protect my country's limited land resources, the state strictly prohibits firing solid clay bricks and their products; with the rapid development of modern buildings and building structures in my country, new wall materials of "lightweight plate structure" have gradually replaced traditional bricks. The "heavy masonry structure" material. At present, the most competitive material in the lightweight panel structure should be a new type of lightweight wall panel made of natural lightweight aggregate, artificial ceramsite and ceramsite products. [0003] Ceramsite is the most economical and practical new type of wall material developed rapidly after ash, stone ...
