The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
Operation and Elements of a Closed-Circuit Ball Mill System . Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media andlined with lifting liners . The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding ...

The cooled clinkers are received from the cooling pans and sent into mills. The clinkers are grinded finely into powder in ball mill or tube mill. Powdered gypsum is added around 2-3% as retarding agent during final grinding. The final obtained product is cement that does not settle quickly when comes in contact with water.
Adjusting mill parameters: Fine-tuning mill parameters such as mill speed, ball charge, filling ratio, and grinding media size can have a substantial impact on the grinding efficiency of the mill. For example, a 10% increase in mill speed can result in up to 10% higher production rate, while optimizing the ball charge can lead to a 5-10% ...
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
A fuzzy controller was designed for the control flow rate inside the ball mill to avoid overfilling or emptying the mill [34]. The fuzzy system was used to optimize the ball milling circuit [35 ...
