Introduction The red mud, alumina production in three ways, namely Bayer, sintering method and combined method, its chemical properties of red mud three different methods produce different. Red mud is an insoluble residue, mainly by fine particles and coarse particles, chemical composition varies origin bauxite and alumina production methods vary. Red mud ceramic sintering process and the use of Bayer red mud, with a certain percentage of fly ash, choose a variety of sintering aids, wet molding, to amount of water Stir press-forming, after forming the body after drying at 110 ℃ 12 hours can be fired. Bayer red mud series of firing temperature is 1160 ℃; sintered red mud series of firing temperature 1140 ℃, incubated for 2 hours under an oxidizing atmosphere, natural cooling, remember to red mud - Fly ceramics. Ceramic body appearance regular, continuous and uniform surface. More consistent shrinkage of about 15%, no cracks and pores scaly tilt matter, the color is yellow-green, fine crystal section, uniform and no density fluctuations. The new sludge treatment technologies - Sludge fired ceramic waste sludge due presents the variability and diversity, it also determines the variety of sludge treatment and disposal of means and methods, it is difficult not to a method covering the whole picture. Some require incineration, landfill and some can, some can be the use of renewable resources, and some want to physical and chemical methods interleaving be disposed of, which is one way the use of ceramic waste sludge fired. So, what is ceramic? Ceramic is a building material. Exterior features most of its circular or oval sphere, there are also some fake ceramic gravel gravel irregular shape. Ceramic shape due to different processes and different. Its surface is a layer of hard shell, this crust was a ceramic or enamel, with a watertight, air protection role, and must be given a higher strength ceramic. Tao particle size, typically 5-25mm. Ceramic, generally used to replace concrete, gravel and pebbles. It enables concrete under the premise of diminished strength, greatly reducing the weight of the concrete. With the overall economic development, ceramic has begun to be used widely used in high-rise buildings, highway piers, marine terminals, thermal insulation, environmental protection and other media, and has been accepted by the market. The use of sludge fired ceramic, for some selective sludge sources to the materials in this vast field to find a way out, it should be said that this is a direction. The difference between the value of the finished product from the use of inputs and outputs, and to weigh the economic desirability should be the primary consideration. To waste sludge fired into the ceramic, its meaning has three: First, the economic significance; the second is social environmental benefits; third is sustainable development. Ceramic equipment, ceramic production line design has extensive experience in ceramic sand production of raw materials is less demanding, almost everywhere, such as: clay, slate, mudstone, shale, coal gangue, fly ash, sludge or industrial solid waste sand and so can be used as ceramic materials. Ceramic equipment (ceramic) is a lightweight aggregate family is the most important member, which is based on various types of clay, shale, slate, coal gangue, fly ash, shale, silt sludge and industrial solid wastes as the main raw material, processed into tablets, roasting artificial lightweight aggregate. It has a low cost of project, good thermal insulation effect; fire antifreeze, bacterial resistance to chemical corrosion; seismic, durability and good.
