Comprehensive inspection of lime kiln; statistical population out brick kiln equipment variety and quantity, to determine the site of the kiln lining damage and destruction of the degree; the overall change of temperature kiln; overall discoloration kiln site. Outside the kiln kiln lining insulation layer, insulating layer is the role of insulation, reducing heat kiln, offset thermal stress due to thermal expansion of the refractory brick lining 3 generated. Thus, the basic requirements of refractoriness and insulation layer is thermally conductive, heat insulating material commonly used in lime brick with Celite, diatomaceous earth powder, slag wool, vermiculite products, expanded perlite powder. In the selection of insulation when there are two points to note, so pay attention according to the conditions, so that the rational use of lime, if conditions allow, the choice to use as high temperature, light weight and low thermal conductivity of the material. Conversely, it can be adapted to local conditions, local materials, the use of cheaper materials instead. You can also use ordinary kiln slag, but regardless of the kind of insulation material must be dried before. Lime kiln quote _ Kim (certified) _ lime kiln by Kim Linyi City Limited.
