Two common heating methods of cement rotary kiln

Cement rotary kiln is mainly used for calcination of cement clinker, is mainly divided dry and wet process two categories for cement production. Cement rotary kilns are widely used in metallurgy, chemical industry, building refractories, sanitation and other industries. Cement rotary kiln is a kind of calcination equipment, which needs heating in the process of operation. There are two kinds of heating methods in cement rotary kiln, one is internal heating and the other is external heating. Within the heating rotary kiln materials and direct contact with the flame and flue gas can be achieved through the furnace oxidation or reduction atmosphere, the inner wall of the brick masonry, head and tail cap lined casting material of high wear resistance, between the cover and the cylinder head and tail of the flexible seal can be complete elimination of dust and leakage of material. Can take multi-file support, the cylinder length of 60 meters, the maximum temperature up to 1600 ?. Large output, for the liquefied petroleum gas, natural gas, gas, fuel oil, pulverized coal, coal and so on. External heating rotary kiln material and the flame and flue gas are not in direct contact with the heat source in the furnace and the cylinder through the heat-resistant steel tube wall heat transfer to heat the material, furnace lining refractory fiber, energy saving. Limited by the heating method and cylinder material, the general length of cylinder ≤ 15 meters, heating temperature ≤ 1200 ?. Yield smaller, suitable for heating methods: electric, gas, fuel, coal and so on. The above is the introduction of the heating method of cement rotary kiln, the user can choose according to their own situation rotary kiln heating, so as to better the production, to ensure the expected production before the start.
