— Two chamber cement ball mill. The outer mill shell diameter is 4.05 m long and the mill can have feed added at the feed end of the first chamber and it then discharges as ground product from the discharge end of the second chamber.First chamber. Fig. 5 shows the distribution of media and its flow in the first chamber of the cement mill.
The cement mill
Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

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 ...
AN EXPERIMENTAL ANALYSIS OF VIBRATION OF A BALL …
Figure 1. Mechanical system of a ball mill with drive The ball mill shell is filled up with a certain amount of the steel balls of various sizes. Together with material which is being ground they are called grinding media. By the rotation of a shell a kidney-shaped cross section of grinding media is formed at the rising side of the shell.
AIR SEPARATORS
Exshaw FM2 successfully uses this idea to make the mill sweep dust fine enough for finish cement. However the box is extremely large to accomplish this. As a rule of thumb for cement mills, the air velocity around the discharge trunnion and hood must be less than 4 m/s. In Exshaw's dropout box they strive for about 2 m/s.
The Monarch Process
The final step is finish grinding. The Monarch finish milling system consists of five ball mills—large rotating cylinders containing steel balls. As the feed enters the mill, the balls continuously crush and grind the clinker and gypsum into a fine powder, a process known as comminution.
Cement grinding optimisation
— Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5–8 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer ...
