Rotary Kiln in Hongxing is the rotary calcining kiln,which belongs to the building material equipments. According to the material processing, rotary kiln can be divided into cement kiln,metallurgical and chemical kiln as well as limestone kiln. Cement kiln is mainly used to calcine the cement clinker, which has dry and wet two type.
Metallurgical and chemical kiln are applicable to the metallurgy industry, iron and steel plant,magnetic roasting of ean iron ore, oxidizing roasting of the chrome ore and josephinite,roasting bauxite in the refractory plant, and roasting clinker and hydroxide in the aluminum plant. Limestone kiln is used to roast active lime for steel and iron plant and ferroalloy plant,and light roast dolomite. Using iron powder production magnetic materials with iron oxide red oxidation, need after high temperature oxidation process, is only the oxidation heating equipment is with the pro-duction rotary kiln, because the rotary kiln stove can”t satisfy the pro-duction oxidation atmosphere, and fuel directly and the heated oxidation material contact, has caused the pollution of furnace materials, make the lime rotary dryer lower yields and greatly influence the quality of the products.The use of cement rotary kiln processing garbage wastes and some technical problems need to solve.
First of all, waste composition complex, their own calorific value difference is very big, in continuous disposal process often causing the innovation “by fits and starts” phenomenon, the kiln regime stability have influence. Hot gases pass along the kiln, sometimes in the Hongxing direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or ’firing pipe‘) which acts like a large bunsen burner.
