Embodiment Construction

[0071] The current cement production process is as follows: figure 1 As shown, firstly, the materials are buffered in the steady flow bin 1 according to a certain ratio and then flow into the roller press 2. After the rolling, the materials are classified and dispersed by the V-shaped powder separator 4, and the unqualified materials are sent to the roller press 3 again by the elevator 3. To the roller press 2, qualified materials are selected into the powder machine 5. Under the action of the cold air valve 6, the superfine powder enters the dust collector 13 by means of the main exhaust fan 9; After the material is ground in the ball mill 8, the fine powder is fed into the dust collector 13 by the tail fan 10; the coarse powder is mixed with the fine powder through the discharge elevator 11, the chute 12 and other equipment, and is analyzed by the online particle size 14 before storage. Become a cement product.

Abstract

The invention discloses an open circuit cement combined and semi-final grinding automatic control method based on C#. The method comprises the steps of completing the data exchange of a DCS system and an online granularity analyzer through OPC communication by using C#, (2) allowing the online granularity analyzer to feed a detected granularity parameter to an engineering station in real time to judge the working condition of a grinding system, and (3) allowing the engineering station to control the grinding system in real time. The invention also discloses a control system with the use of the open circuit cement combined and semi-final grinding automatic control method based on C#.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic control method and system for open-circuit cement combined with semi-finish grinding based on C#. Background technique [0002] The control of most closed-circuit cement combined grinding systems in China is mostly done manually by operators. The open-circuit cement combined semi-final grinding system has the characteristics of pure lag, large inertia, multi-variable, strong coupling and time-varying model, which increases the difficulty of manual control of the mill. In addition, during the working process of the closed-circuit cement combined grinding system, phenomena such as blocked grinding, full grinding, empty grinding, ultra-fine fly ash and overload of the hoist at the end of the mill occur from time to time, which not only affect normal production, but also reduce cement production. Efficiency reduces the service life of some equipment and increa...
