Intelligence makes the cement grinding system more stable and efficient


The downward trend in cement demand is coming to the fore, energy prices remain high and the cost side of cement companies is under pressure. Due to frequent falls in prices, profits are constantly suppressed and even incurred losses.

At present, improving energy efficiency and reducing cost pressure have become important breakthrough points for cement companies to enhance their comprehensive strength and market competitiveness.

Industry experts said cement companies should pay attention to grinding technology research. A “major consumer of power” in the cement production chain, the grinding system consumes more than 60% of the entire cement production process. High energy consumption and low efficiency have always been a pain point in terms of energy saving and consumption reduction in the cement industry.

Industry experts pointed out that the current energy saving and consumption reduction methods in cement grinding systems are mainly divided into three aspects: first, the use of more efficient classification equipment in the grinding system; Secondly, upgrading the pre-grinding system such as tube mill. The front of the machine increases pre-grinding efficiency. The third is to implement effective modifications in the tube mill section to improve the grinding efficiency and the rate of finished products, creating good prerequisites for the effective classification of the dust separator. All three reduce actual cement grinding power consumption by increasing the output of the grinding system.

Controlling the power consumption of the grinding system is of great importance for cement companies in terms of saving energy, reducing costs, increasing efficiency and ensuring the green development of the cement industry. However, the energy-saving and consumption-reducing transformation of the cement grinding system still faces a significant challenge - the performance of the materials to be ground in the cement grinding systems of various enterprises varies greatly.

The properties of the clinker used in different cement factories, especially the mixed materials, such as grindability and moisture, are quite different. Even after homogenization the average value cannot be very stable. Even if two sets of identical production equipment, the quality and output of cement produced by different factories are often quite different, especially the grinding power consumption indicators.

Industry experts suggest that the fluctuations in the on-site grinding system can be resolved through the evaluation and analysis of intelligent equipment, and the operation of the cement grinding system can be made more stable. Using intelligent methods to transform the grinding system can improve production efficiency and product quality. , the system reduces energy consumption, promotes energy saving and emission reduction, and provides good economic and environmental benefits.

However, due to material differences, a universal smart solution is not currently available. Only through on-site inspections can we analyze specific problems and implement appropriate measures depending on the situation. Zou Weibin pointed out that cement companies need to do more experiments and spend more time on the characteristics of the milled materials. Research in this area will help advance smart technology and thus significantly increase the energy efficiency of the cement grinding system.
