If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

Overview of Ball Mills. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It's called a "ball mill" because it's literally filled with balls. Materials are added to the ball mill, at ...

conditions by considering a more realistic ball size distribution (BSD). The ball size distribution for the first filling of ball mills is typically selected based on Table 1s proposed by Bond (1958). Of course, balls' shape and size distribution under various factors, including impact, erosion, corrosion, and crushing, change over time.

Abstract Ball drum mills (BDM) are one of the main types of coalgrinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP's own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and ...

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.
