Rotary kiln process materials, good control of the calcination temperature is a very important technology, but from the entire process, the factors affecting the calcination temperature is very much as how much quantity, firing high and low temperature, exhaust volume size and location of the coal pipe, kiln speed of speed, the degree of wet and dry materials that how these factors influence the kiln temperature changes in the level, the following technical staff from the YuFeng Heavy kiln eleven to explain. In the rotary kiln material in the process, if there is little or kiln cutting off material; firing temperature is high; exhaust large; Coal tube position by li; kiln speed slow exhaust large; wet kiln kiln slurry water Small, etc., this time will become high temperature kiln. In the rotary kiln material in the process, if there is more than cutting kiln; kiln feed preheating bad, decomposition rate; Wet Kiln add water; firing temperature is low; kiln sealed bad; big air leakage ; kiln fast, exhaust
