Partial Process of Calcined White Cement Clinker by Rotary Kiln

1.In the normal calcination white cement clinker rotary kiln, from the rotary kiln mouth 1 ~ 2m often has coal lane, coal ring knot is not a bad thing, and the coal ring knot is appropriate to the rotary kiln calcination favorable. Due to pulverized coal powder from a duct into the burning zone burning, and the coal ring knot plays a protective rotary kiln flame burning and improvement the role of the flame temperature. So that the cold air of the rotary kiln and bleach inside the water vapor to the coal ring to block, cannot directly affect the rotary kiln flame calcination.
2.In the case of rotary kiln before the end of coal lime, clinker granules is uniform and tidy, because the materials stay longer in the burning zone, the temperature is higher and that is fully calcinaed. At the same time we also take the height of the rotary kiln brick, so that the thickening of the cooling strip material also extends the time of the clinker in the rotary kiln in the high temperature zone. Cooling with the material layer thickening is bound to improve the temperature of the rotary kiln, the injection of kiln into the rotary kiln combustion effect, accelerated the combustion of coal. That is suitable for rotary kiln calcination white cement clinker process requirements, and play a role in promoting the firing.
3. We can find the rotary kiln coal lane when the general firing zone is not easy to ring, rotary kiln calcination atmosphere is good, and the quality of production are higher. If the equipment can be trouble-free, the operation rate is quite high, when the rotary kiln is in a good cycle. It is noteworthy that this state burned with a rotary kiln leather knot has to fall, to prevent the idea of carelessness, failed to control the rotation of the kiln tail will be burned with the temperature burned too high so that damage to the kiln leather and Lining, the emergence of rotary kiln melting, brick and other adverse conditions, affecting the operation of the rotary kiln cycle. Coal lap cannot be too high, clinker is difficult to turn over the coal ring when the need for dressing the coal ring, or will affect the kiln clinker kiln normal discharge.
4.Rotary kiln design is a material to stabilize the process, rotary kiln screw conveyor is measured speed, it is through the sensor will be directly reflected in the feed to the rotary kiln on the instrument panel, to the operator an intuitive quantitative concept, and facilitate the control of the entire rotary kiln parameters. The conveying amount of the raw material screw conveyor is always larger than that of the rotary kiln metering screw conveyor, and the excess raw material enters the return pipe to the raw material hoist.
After a lot of experiments of our rotary kiln technical staff, at the same time, improve the process of not adapting to the kiln white cement production process accordingly, then summarize the above-mentioned rotary kiln calcined white cement clinker process.
