Generally, steel balls must not fill more than 35% of the ball mill. The size selection of grinding balls can be calculated using the following formula: Dm <= 6 (log dk) * d^0.5. Here, Dm = the diameter in mm of a single ball. d = the diameter in mm of the biggest ore piece ore in the mill.
A cement ball mill is generally divided into two or three grinding compartments. The larger the length-diameter ratio of the ball mill is, the more compartments there are.
Operation and Elements of a Closed-Circuit Ball Mill System . Cement ball mills typically have two grinding chambers.

Abstract In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to ob tain the product, but it is usually more expensive,
There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].
The applications of grinding media ball associated with the bead mills are listed as under: It is used in the construction industries to grind concrete or larger blocks into smaller particles; It is also used to crush the materials for a better user experience; Various milling materials are also ground with the help of the grinding media ball
Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 150mm according to different grinding requirements. In a cement ball mill, generally, φ50-100mm steel balls are used in the coarse grinding chamber, φ20-50mm steel balls are used in the fine grinding chamber. 2. Short Cylinders.
