The Crucial Installation Apply in Limestone Calcination

Rotary kiln is the main equipment for limestone calcination; there are some operation key points for the great capacity and long service life. They are mainly in rotary kiln preheated system and dust collection system. Hongxing Machinery mentions the rotary kiln manual for you in the following.

Firstly, the preheater can't be fed with little materials, too much materials or mixing materials. We should observe outlet temperature of rotary kiln preheater system, so as to adjust the feeding materials. Adjust the push rod an interval according to the raw material system situation. If overhaul refractory in the preheater, we must clean the feeding material. Dust collection system inlet temperature should be controlled under 180 degrees centigrade. Differential Pressure is less than 1.8 KPa. Rotary kiln dust collection system equipment obstacle should organized by operator.

If some rotary kiln parts have much worn and the precision, such as the wearing part has reduced during the operation, the operation efficiency will be declined, so that rotary kiln wearing parts must be repaired or changed at regular intervals. Of course, we do not only persist in the preventive maintenance, but also must list the maintenance schedule. At present, we can carry out the operating maintenance and the medium maintenance during the refractory maintenance. We should also do some overhauls within 2 or 3 times stoppage of the rotary kiln (during refractory maintenance).

Whether the rotary kiln center line maintains a straight line during the kiln operation, it mainly depends on the locations of support roller devices. Therefore, we should pay more attention to the installation of rotary kiln support roller devices. Hongxing Machinery analysis the following requirements, which must be satisfied for the installation of rotary kiln support roller devices.

Rotary kiln drive system would be maintained after the refractory has been built, but it must be rapidly finished within 8 to 12 hours. If some overhaul must last 10 to 20 days, the wearing parts must be changed. check and adjust the whole rotary kiln calcinations system, for example the changes of rotary kiln cylinder section, girth gear, tyres, supporting rollers, thrust roller and other important parts, the adjustment of the center line of the kiln, etc.
