Cement Kilns Introduction:
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydrauliccement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology.

Cement Kiln working Principle:
Under high temperature, the cement rotary kiln operates slowly under heavy load and alternating speed. The maintenance of the accessory equipment and the level of the thermal system control are related to the safety and efficiency of the rotary kiln operation.The maintenance of the transmission device is focused on the lubrication, running state, dynamic detection and meshing accuracy of the gear, and the installation accuracy of the supporting device determines whether the rotary kiln can operate safely and reliably.In operation, attention should be paid to the distribution of bearing capacity, the arrangement of the supporting wheel, the upward and downward pressure and time of the hydraulic gear, the bearing force of the wheel, the gap between the wheel and the pad.The sealing device directly affects the thermal system and operation cost of rotary kiln.Reinforced rotation The analysis of daily maintenance data of kiln is beneficial to the management of equipment.
