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.
The choice of grinding media The choice of grinding media will always depend on the material to be ground. You need to assess its granulometry and the grinding process. You also need to look at the relative importance of the wear mechanisms in the process.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11 . The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.

Mass balance of the circuit was done by JKSimMet
Grinding cement in ball mills. The principle of the ball mill operation is simple it consists of a rotating drum and grinding media cylinders, balls etc. The material is placed into the drum which starts rotating. The grinding media and the substance both come in circular motion and at a certain point drop from the walls the bottom of the drum.
Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the VRM. In ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough top-size media to grind the mill feed materials.
1. Roller Press Cement Pre Grinding System. The most noticeable feature of the roller press cement pre grinding system is that the fine material power ground at the middle part of the roller will be sent to the ball mill for further grinding. The cement grinding process in this system is rather simple with less equipment required.
Cement Plants. The cement industries are using the most diverse range of grinding media, ranging from 17 mm to 90 mm, which is divided in the 23 chambers. The large focus is on the power consumption and increased output. The grades of HCGM of SBIPL are such that the balls retain their shape as they tend to wear.
media shape and mill power. The objective of this dissertation was to investigate how media shape affects grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe ...

2 The pre-grinding adds a roller press to the cement grinding system. In this system, the clinker is extruded circularly, dispersed and separated, and becomes powder with diameter less than 2 mm Gradation of Grinding Media. The gradation of grinding media is also an important factor in improving the efficiency of ball mills.
