A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size.
In the case of new orders, vertical mills have increased their share to over 60 and ball mills have fallen to less than 30 . It is somewhat surprising that the number of different grinding processes and mill types used by the industry have increased rather than decreased. The throughput capacities of the employed mills have risen, but in some cases this has brought machines, e.g. gear units
cut down energy consumption in the grinding unit. Installa tion of a roller press before rolling mill or cement mill in cement plants is nowgmon feature. In a roller press, clinker material is subjected to extreme pressure between opposing rollers for a short time, Fig 1. One roller is fixed and other roller can move by about 50 mm laterally perpendicular to rotating

We often see ball mills used for clinker grinding, while vertical mills tend to bemon today for rawminution. In older cement plants, however, both process steps are equipped with ball mills and their corresponding drive systems. But many of these gear units have seen better days and might no longer satisfy your needs.

the mill is used primarily to lift the load medium and charge. Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill
A Ball mill is a horizontal cylinder partly filled with steel balls or occasionally other shapes that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high chromium steel.
