The production process of the cement rotary kiln is very complex and the production equipments are diverse. There are large numbers of 1 / O points, and the distribution is dispersed. Therefore, the framework of the control system with reasonable design is extremely important for thefurther optimization of the production process and the technological innovation. There is a wide range of the furnace. According to the different working principles, they can be divided into roller kiln, rotary kiln, shaft kiln. According to the applicable materials, they can be divided into the glass furnace, ceramic kilns, cement kilns and so on. The cement rotary kiln includes the precalciner kiln, preheater kiln, dry kiln, and wet kiln. The cement rotary kiln with decomposing furnace outside the kiln which is also known as precalcining has become the new direction of the development of the cement rotary kiln due to the high labor productivity, strong operability and good quality of the products. Therefore, improving the production efficiency, improving the control method and designing the intelligent monitoring system of the rotary kiln has very important significance.

At the same time, people have higher requirements for the management and operation. The management and operation of the whole system requires responsibility and heavy workload. If only technicians take the responsibility, even the skilled personnel, a large number of people will be needed. And the operation of the whole production line may be influenced due to the technical level, operation habit, motion and mistakes. For this reason, to have an excellent automatic control system seems to be indispensable and it will certainly improve the operation ability and level of the whole production line. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery,

The production technology of the predissociation is quite complicated, and one production line will need more than 900 motors and valves, hundreds of mechanical equipment and thousands of switches, hundreds of analog testing point and tens of regulating loop. In order to ensure the normal production and the quality of the products, only automatic control technology can make it come true.

In the engineering design, that is widely used includes internationally advanced computer control technology, communication technology and graphical display technology, and the diffuse type control system of decentralized control and centralized management is adopted. At present, about 200 production lines have been put into use. The main work of the automatic control system is:

1. On the basis of concluding the long time of operation experience, the designers developed optimized control software that can be used in all main links of cement production, and the software plays the role of stabilizing the operation, optimizing the operational factor, saving energy and reducing the consumption and improving the output and operation rate.

2. On the professional machines, relevant complete electric drive, auto testing and control devices are equipped, and they are also included in the DCS system, thus form a control pattern of decentralized control and centralized management.

3. The mature business network is combined with the DCS system, and the production management information system that is used in the cement plant is developed. On this basis, the content management information system is developed which provided advanced management means for the enterprise management modernization.
