Reasonable Rotary Kiln temperature regulation is not only conducive to the stability of product quality, but also to charge the bonding

surface is equal to the speed of refractory wear rate, keeping the thickness of the inner surface of the refractory ring formation, thus

prolonging the Rotary kiln age. Rotary Kiln temperature at various points by the PCI and wind technologies for joint control.According to

the reactivity of coal and ore, charge preheating temperature control 850 ~ 900 ℃, the reaction zone controlled at 950 ~ 1 150 ℃,

discharge temperature of 900 ℃, the exhaust gas temperature 850 ~ 950 ℃.Installed on the Rotary kiln shell has 10 groups with a total

of 12 thermocouple protection tube, the thermocouple can be continuously measured by solid phase and gas Rotary kiln temperature,

and wireless transmission technology transfer through to the control room, the computer displays and records temperature changes

trend.
