Cement rotary kiln belongs to building materials equipment category and is a kind of lime kiln. Rotary kiln can be divided into cement rotary kiln, metallurgical chemical rotary kiln and lime rotary kiln according to different materials. Cement rotary kiln is the main equipment for dry and wet cement clinker production lines. Cement kilns are mainly used for calcination of cement clinker, divided into two categories: dry production cement kilns and wet production cement kilns.
The cement rotary kiln operates at a heavy load and alternates at a slow speed under high temperature conditions. The maintenance of its accessory equipment and the level of thermal system control are related to the safety and efficiency of the rotary kiln operation. The maintenance of the transmission device focuses on the lubrication of the equipment, the running state, the dynamic detection and the meshing accuracy of the large and small gears; the installation accuracy of the supporting device determines the safe and reliable operation of the rotary kiln, and attention should be paid to the reasonable control of the load distribution of the supporting rollers during operation. , The arrangement form of the supporting wheel, the upward and downward pressure and time of the hydraulic retaining wheel, the force of the supporting wheel, the gap between the tire belt and the backing plate. The quality of the sealing device directly affects the thermal system and operating cost of the rotary kiln. Strengthen the daily maintenance data analysis and analysis of the rotary kiln, which is conducive to the management of the equipment.
