4. Ball mill improvements High efficiency separator to minimize over-grinding Latest QDK high efficiency separators from CPB can achieve a bypass of <10% & improve an existing mill performance by 20% or more, as well as producing greater cement consistency.

Besides, the performance of our cement ball mill has reached international advanced level, and it is suitable for close-circuit grinding, together with separator. Two chamber mills are used for grinding slag, cement,and similar materials. They are typically arranged in a circuit with high efficiency separators.

For each cement type a PID set is selected and put in operation in a closed circuit cement mill. The performance of the regulation is evaluated after a sufficient time period, concluding that the developed design combining criteria of both robustness and performance leads to PID controllers of high efficiency.

In closed circuit grinding, a high efficiency separator (O-Sepa or Sepax, Sepol) is in operation which separates the material that is ground from the mill in to coarse and fine. The fine material is the product while the coarse material is recirculated back in to the mill for further grinding to the required fineness. Vertical roller mills (VRM)

This is called a combi-grinding circuit. The main feature of such a system is the pre-grinding of cement clinker in the POLYCOM and a final grinding in the ball mill. The specific power consumption compared to a ball mill cement grinding is significantly lower and additionally paired with a 30 to 40 per cent increase in output.

Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
