At present, China's Light Expanded Clay Aggregate (LECA) production equipment is used in industrial kilns reversed. Was the main kiln degree cylindrical body and about 3 ° inclination placed in care roll on. Material into the kiln at the high end, in effect doing reverse activity kiln, the material rolled from high to low point, but also, at the kiln, high pressure air pulverized coal is injected into the kiln, and it plenty of burning calories attack happened so that the material physical and chemical changes occurring swelling scene, after cooling both for ceramic. First, the principle of operation of monocular ceramic kiln produced ceramic reversal of the primary main equipment include: raw material storage silos, dust chamber, fan, main kiln, coal injection system, control cabinet. One in the lower part of the raw materials warehouse feeders arch kiln speed and the amount of coal are variable speed, in order to adjust its parameters to obtain the maximum yield under the premise of guarantee product quality. Production process Lytag production, because different components of production of raw materials, production processes relative to it there are differences. Production of raw materials companies Lytag have conventional and unconventional. (1) produced Lytag the production process is as follows: raw materials (fly ash + quantitative admixture) mixing mill - granulation - burning bulge - stacking - transport. (2) production should be used binoculars reverse Lytag kiln preheating kiln and boring segments that can control its own speed, in order to control its raw form the basis preheat time. Clay ceramic recent years because of restrictions because the site was the capital, and in some areas has been stopped production and use. However, some areas may be applied river silt, abandoned mountain soil, etc. produced. Raw stir - granulation - pick - Sintering - stacking - transport. Second, the concept of ceramic materials ceramic many, many types of ceramic also, so will a lot of color. Unburned ceramic solid discards due to the differences, individual color, normal gray and black, no gloss appearance, as firing ceramic lubrication. Exterior features a large ceramic partial circular or oval sphere, but there are some fake gravel is not round or oval ceramic spheres, and showed irregular shaped gravel. Ceramic shape due process and individual differences. Its appearance is a layer of sturdy shell, this layer of ceramic or enamel shell was with Paul gas impermeable effect, and pay with ceramic high strength. Color due to the appearance of ceramic materials and processes employed and individual differences. Firing ceramic colors are mostly dark red, ocher red, there are some remarkable species is pale yellow, gray and black, gray, blue gray and so on. Third, the use of ceramic ceramic having excellent features, such as low density, high pressure tube, high porosity, high softening coefficient, excellent frost resistance, excellent alkali aggregate reaction and the like. Special because the ceramic density, internal porous, shape, composition more uniform, and possessed strength and consolidation inevitable, and therefore has a lightweight, corrosion, frost, shock and superior barrier properties such as multi-functional characteristics. Application of ceramic these excellent features, it can be widely used with building materials, gardening, food and beverage, fire-resistant insulation materials, chemicals, petroleum and other parts, the use of increasingly wide scope, is continuing to expand. Ceramic creation and production in the beginning, it is mainly used in building materials category, as skills development and function of the perception of ceramic increasingly deepening from time to time, the use of ceramic materials has long been beyond the traditional limitations, from time to time to expand its use of new category. Ceramic building materials currently in use, and had dropped from 100% to 80% in other areas, accounted for 20%. Useful from time to time along with new ceramic development, its share in other areas will gradually increase.
