Cement rotary kiln is the main equipment for calcining cement clinker, which is widely used in cement, metallurgy, chemical industry and other industries. The rotary kiln is composed of a cylinder, a supporting device, a supporting device for a blocking wheel, a transmission device, a movable kiln head, a kiln tail sealing device, a combustion device and other components. The rotary kiln has the advantages of simple structure, reliable operation and easy control of the production process.

There are two main types of dry type cement kiln and wet type cement kiln. In addition, metallurgical and chemical kilns are mainly used for roasting of lean iron ore in iron and steel plants of the metallurgical industry; oxidation roasting of chromium and nickel iron ore; roasting of high alumina vanadium ore in refractory plants and roasting clinker and aluminum hydroxide in aluminum plants.

Improving the operation rate of rotary kiln starts from reducing the damage operation. Rotary kiln shutdown, waiting for work due to inconsistency of the front and back processes, and abnormal conditions such as inspection and maintenance of the rotary kiln. This situation  will not produce added value, but it will also damage the operation and move by transportation. Or handle (organize and prepare for inspection), check the quantity, quality and other series of operations that do not produce added value.

Therefore, if a rotary kiln manufacturer wants to improve the operation rate of the equipment, it is necessary to know how to reduce the above operations. Therefore, only the operations that produce added value such as processing and assembly are ideal operations; that is, the smooth supply of parts in the previous process of the rotary kiln reduces the time loss, and in the shift operation, it is the configuration of the staff and the balance of the workload In order to improve the operating efficiency of rotary kiln.
