Clinker size and cement grinding. ... Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that in some cases the formula will result in the ...

How Overflow Type Ball Mill Works. Material Feed: The raw material is fed into the mill at one end and travels through the mill by rotation. The feed enters the mill at a specific rate, ensuring a controlled grinding process.; Grinding Process: As the mill rotates, the grinding media crushes and grinds the material into a fine powder. The wet …
Ball mills and grinding tools Cement ball mills are typically two-chamber mills (Figure 2), where the first chamber has larger media with lifting liners installed, providing the coarse grinding stage, whereas, in the second chamber, medium and fine grinding is carried out with smaller media and classifying liners.
To investigate the effects of grinding media shapes on the grinding kinetics of ball mill cement clinker, the grinding effects with ϕ20 mm balls and ϕ20 × 20 mm cylinders on six different size fractions, i.e. − 4.75 + 4.00 mm, − 4.00 + 3.35 mm, − 3.35 + 2.36 mm, − 2.36 + 2.00 mm, − 2.00 + 1.70 mm and − 1.70 + 1.18 mm of cement …
