1. Introduction. In the cement industry, grinding is one of the most consuming energy stages in the production units. Around 65% of the total used electrical energy in a cement plant has to be utilized to grind raw materials, coal, and clinker [1,2].Through the process, many variables can affect the efficiency and productivity of this dry grinding …

The better mills on the market have an efficiency of about 8-9 % which means that only 8-9 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ball ...

Step 5. Select a vessel size that satisfies gas capacity, water-drop removal, and liquid-retention time requirements. An 84-in. × 13.4-ft separator satisfies the requirements, so you would round up to an 84-in. × 13.5-ft vessel. Similarly, a 90-in. × 12.5-ft separator would also be satisfactory.

If the bypass is 40%, and if the production is 100 t/h, then, naïvely speaking, this means that 40 t/h of good product is returned to the mill. This could be, naïvely, translated as an efficiency of 100/140 = 70% and would indicate that the production could be increased by 40 t/h if the separator would be efficient.

The circulating load can be slightly changed during the operation by changing the mill feed rate or changing the separator settings. However, at a long run, the resulting circulation load, based on the factors above, will establish. The range of normal circulating loads is shown in the graph in fig. 6, based on OPC and high-efficiency separators.
