The geometry of a mill with conical ends is shown in Figure 8.6. The total volume inside the mill is given by Vm 4 D2 mL 1 2(Lc L) L 1 (Dt/Dm) 3 1 Dt/Dm (8.16) The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball 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 drum is generally divided into two or three chambers, with different size grinding media.
media in the mill by looking at the mill grinding efficiency. At that time, it was difficult to acquire a lot of valuable information as robustness in an aggressive environment was not assured. Twenty years later, the Sensomag is able to show this interaction by looking on the pulp position angle and media angle.

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.
The segmentation of grinding and milling systems. Module 2 Ball mills. This module will cover the technology of ball mills used for raw and finish grinding in the cement manufacturing process. * Mechanical description of the different types of mills. * Ball mill grinding equations and dimensioning. * Mill internals, media, liners and diaphragms.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and
Mining and processing plants use rotating drum mills (pic. 1). Depending on the form of the grinding media there are ball mills, rod mills, pebble mills and autogenous grinding mills. Grinding media — iron and steel balls with diameter of 15-120 mm, steel or cast iron cylpebs dimensions (diameter and length) of 16 to 25 and 30 and 40 mm, round steel bars with a diameter up to 130 mm and a length equal to the length of the drum. The right choice of grinding media
