Embodiment Construction

[0025] Below in conjunction with embodiment the present invention will be further described:

[0026] 1. The ingredients of cylindrical attapulgite construction waste ceramsite are composed of the following components by weight percentage: high-viscosity attapulgite clay powder 6%, attapulgite clay tailings powder 20%, construction waste powder 56%, red bentonite powder 8%, diatomite tailings powder 6% and wood powder 4%.

[0027] 2. The production method of cylindrical attapulgite construction waste ceramsite: (1) Add the ingredients of cylindrical attapulgite construction waste ceramsite into the mixer and mix them, and then input them into the extrusion granulator for granulation. The particle diameter is controlled at 12 mm, and the particle length is controlled. 20-35 mm; (2) input the granulated particles into the internal heating rotary kiln for roasting, the roasting temperature is controlled at 800-850 ° C, and the roasting time is controlled at 3 hours; (3) the roast...

Abstract

The invention discloses a cylindrical attapulgite construction waste ceramsite. The key point of the technical scheme is as follows: the cylindrical attapulgite construction waste ceramsite comprises high viscosity attapulgite clay powder, attapulgite clay tailing powder, construction waste powder, red bentonite powder, diatomite tailing powder and wood chip powder. The ingredients of the cylindrical attapulgite construction waste ceramsite are mixed, granulated, roasted, cooled, screened and packaged to obtain the cylindrical attapulgite construction waste ceramsite. The cylindrical attapulgite construction waste ceramsite is of cylindrical shape, has rough and hard surface and has a lot of fine pores in the interior; and the spherical attapulgite refractory ceramsite is a construction ceramsite with light weight, high strength, low thermal conductivity, high refractoriness, stable chemical property, durability and good heat insulation and sound insulation effect. The comprehensive utilization of construction wastes and tailings in producing the cylindrical attapulgite construction waste ceramsite is beneficial for increasing the resource utilization rate, turning waste into wealth and protecting the environment; and the cylindrical attapulgite construction waste ceramsite disclosed by the invention is suitable for producing ceramsite concrete as well as heat insulation and sound insulation materials.

Description

technical field [0001] The invention relates to ceramsite, in particular to a cylindrical attapulgite construction waste ceramsite. Background technique [0002] Construction waste refers to the waste generated during the construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals. The components of construction waste include: scattered mortar and concrete, broken bricks and broken concrete blocks, yellow sand, stones, block stones, muck, scrap steel bars, scrap iron wires, various scrap steel fittings, metal pipeline scrap, scrap Packing boxes and bags of bamboo wood, wood chips, shavings, various decorative materials, etc. [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...
