AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal appliions.

The operating principle of the ball millBy increasing the grinding balls size, decreases the mill working surface and reduced mill productivity. It is important to follow the degree of drum filling by grinding balls, because with a large filling rising grinding balls collide with falling balls. Established impact of design mills

design of horizontal wet ball millBall Mill Appliion and Design - Paul O. Abbe. The residence time in ball mills is long enough that all particles get consistent treatment, which also provides a narrow particle size distribution. Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 1.5”.

Industrial Ball Mills: Steel Ball Mills and Lined Ball Ball Mills Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s.
