Cement plant cost saving and control system studying

Cement mill is the key equipment in the cement plant process, high energy consumption, large wearing and automation control level directly affects the cement plant cost, production and energy consumption.

At present, China's cement plant used automatic batching system to achieve the control of the proportion of materials under the various materials, so that the chemical composition of the production process to meet the requirements, but in the quality control and production there are still exist following problems: to batching material according to personal experience, capacity adjust base on in time test which will cause adjust delay, while then cause fineness (Or specific surface area) fluctuation; there is no accurate and effective means of measuring the level of material level; It is difficult to achieve the highest capacity and stability under the premise of quality, and thus the power consumption of the grinding process is relatively high; when too many raw material inside the mill will lead to over running of powder, temperature increases, fineness become large; When the mill material is too less, it will cause increased wearing, the sharp decline in production and other issues.

"cement plant cost optimization energy-saving control system" to safe and economical operation as the goal, adapt self-optimization, adaptive and other advanced control algorithms for the grinding process characteristics and conventional control algorithm combined with control strategy to achieve grinding process automatic, to ensure that the grinding process is safe, continuous, economical and stable, suitable for cement raw material grinding and cement grinding process.

Through the noise sensor to detect the mill noise signal, the transmitter processed it to be accurately reflected standard signal, in order to achieve accurate measurement of the mill level; control mill feeding volume, inlet air volume and classifier speed, to adjust grinding ventilation and the amount of material, the material flow rate and the cycle load, and optimize the mill material level, material flow speed and cycle load, to ensure that the mill can always be in stability running condition while ensuring the fineness; the product fineness can be stabilized, the uniformity is improved, the quality is ensured; There is great significance to reduce the power consumption and improve the economic benefit for reduce cement plant cost with significant economic benefits and good social benefits.
