Process Overview of Calcining White Cement Clinker in Rotary Kiln

1. In the normal calcined white cement clinker in the rotary kiln, away from the rotary kiln 1 ~ 2m department often bear coal lap, which is not a bad thing, and coal laps knot was appropriate to the rotary kiln calcination benefit. Because the coal powder from a primary air pipe into the firing zone with the combustion, and the coal circle to protect the rotary kiln flame combustion and improve the role of the flame temperature. So that the rotary kiln cooler and bleach inside the water vapor to the coal ring block, cannot directly affect the rotary kiln flame burning.

2.In the case of rotary kiln front coal lap, clinker grain uniform and tidy, because the material stay a long time in the burning zone, the temperature is high that is fully calcined. At the same time, we have also taken to increase the height of rotary kiln brick, so that the thickening of the cooling zone material also extends the rotary kiln clinker in the high temperature zone of time. The thickening of the cooling zone will increase the temperature of the rotary kiln, which will help the pulverized coal injected into the rotary kiln and accelerate the combustion of pulverized coal. That is suitable for rotary kiln calcined white cement clinker process requirements, play a role in promoting the firing.
3.We can find the rotary kiln coal lap when the general firing belt is not easy to ring, rotary kiln calcined atmosphere is good, production and quality are higher. For example equipment can be trouble-free, the operating rate is quite high, when the rotary kiln is in a good cycle. It is noteworthy that this state of burning with rotary kiln skin knot down, to prevent the thought of paralysis, failed to control the rotary kiln tail material will burn with the temperature burned too high to damage the rotary kiln skin and Lining, there have rotary kiln melting, exposed brick and other adverse conditions, affecting the operating cycle of the rotary kiln. Coal ring cannot get too high, clinker more difficult to turn over the coal circle when the coal ring to be trimmed, otherwise it will affect the normal rotary kiln clinker expected.
4. The stable role of rotary kiln tail, calcined white cement clinker rotary kiln system temperature is higher than ordinary cement kiln, the type of rotary kiln with a stable tail feeding device is particularly important. "Rotary kiln stable need material stability, material instability is unstable rotary kiln."
5. The rotary kiln designs a stable material process, into the rotary kiln screw conveyor is the measurement of speed, it will feed through the sensor directly to the rotary kiln head of the instrument panel, giving the operator an intuitive concept of quantity, easy to control the parameters of the entire rotary kiln.
After a large number of our rotary kiln technical staff of the experiment, while not suited to the rotary kiln white cement production process for the corresponding improvements, summed up the above rotary kiln calcined white cement clinker process, welcome to customers leave a message or call us for consultation.
