Hongxing Rotary Kiln Has Different Process and Value

Rotary kiln is mainly used for oxidizing and roasting of lean iron ore in iron and steel plant of metallurgical industry; the oxidizing and roasting of chromium and nickel iron; the roasting of high bauxite ore and aluminum clinker and aluminum hydroxide in refractory material factory; chromium powder ore roasting in chemical plant. Rotary kiln has extensive applications in mechanical, physical or chemical treatment of solid materials building materials of metallurgy, chemical industry, environmental protection and many other industries.

Rotary kiln adopts insulation materials and high temperature insulation coating materials. The coating is inorganic water paint, which adopts high temperature solution, ceramic hollow selected beads and silica alumina fiber as the inorganic materials for refined processing. The temperature is in the range of -80 - 1800 ℃, and coefficient of thermal conductivity is only 0.03W/m.K. It has small proportion and light weight, which can greatly reduce the weight of the painting objects. The heat resistant and high temperature insulation coating can effectively inhibit and shield the infrared radiation and heat; the insulation suppression efficiency can reach about 90%. The material can inhibit the temperature of heat radiation and heat conduction loss of heat, the internal heat of rotary kiln can maintain 70% loss. In addition, the coating has features of fire retardant, wear resistance and pressure resistance, insulation resistance against wear, acid and alkali resistance, light weight, convenient construction, long service life, etc. 

Hongxing rotary kiln has firm structure, stable operation, high-quality finished products, which can provide efficient shaft preheater and advanced five stage cyclone preheating for customers. In addition, in the aspect of environmental protection, the use of cement kiln for the incineration of hazardous waste, garbage will not only make the waste minimization, harmless, and the waste can be used as fuel, so as to save coal resource. At the same time, Hongxing Machinery has taken the lead for the rotary kiln system in the application of the sulfur removal technology, which can reduce the content of S in 0.05%~0.08%. Hongxing rotary kiln has a good effect for improving the steel quality and this technology is ranking the international leading level.
