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 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
Ball and Rod Mills. Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved …
Rods are placed parallel along the length of the rod mill. Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but …
For rod, ball, or pebble mills the peak is usually near Vp = .50, while actual observations as low as V= .42 have bean made in some ball mills (Rowland, 1973). See Figure 2. Power draw is not significantly affected by the presence of the slurry in the mill. While the presence of the slurry will effect the charge density, the charge swelling ...
The main difference between a rod mill and a ball mill is the grinding medium. Rod mills use long steel rods as the grinding medium, while ball mills use steel balls. Additionally, rod mills are better suited to handling larger feed sizes, and they create a more uniform particle size distribution than ball mills. What are the main components of ...
Fineness. The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm.
