What are the differences between ball mill and rod mill
Mar 08, 2021Ball mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.
Dimensionality in ball mill dynamics
May 01, 19911) Overload in overflow ball mills is due to the approach to a critical axial flow velocity for pulp of 0.072 m/s. 2) While so far important only with 5.0 and 5.5 m diameter mills, it should be found with smaller mills in combinations of very high circulating loads, excessive L/D ratios, very soft ores or coarse grinds. 3. A proper balancing of lower Lf and higher F values can reduce the risk

motor selection for ball mill
Mar 09, 2016A ball mill is a device to grinder any media. I have an issue to select a proper motor. I see some challenges here : 1-The jar will contain metal balls which will be a heavy load to rotate. (I think 1/3 HP at least would be needed) 2-The jar rotation should be constant (80 RPM).

Large Ball Mill Scale
Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor.
Mill drives: the desire for increased power and the
design limitations on mill diameter have been exceeded. For example, the D:L ratio for 32 ft dia. mills decreased from 3.00:1 to 2.17:1 over 35 years until the advent of 36 ft dia. mills in 1973. The D:L ratio for 36 ft dia. mills decreased from 2.53:1 to 2.06:1 over 23 years until the first 38 ft dia. mill was purchased in 1996. The 38 ft dia.

HOW BALL MILL WORKS?
Oct 10, 2016Pipe ball mills have a drum length longer than three drum diameters. Pic. 2. Cylindrical balls mill. A cylindrical ball mill used for grinding the coarse material. This mill should have a short length because the balls distributed uniformly over the entire length of the mill and during rotation obtained the same pulse. The drum diameter of the
An analysis of the selection function for mills using
Abstract The present study deals with an analysis of the selection function for mills using balls as grinding media. The grinding mechanism assumes that a particle caught by two colliding balls will be ground only if the ball impact generates or activates at least one single crack within the particle causing the fragmentation. The derived selection function becomes convex in relation to

Calculate and Select Ball Mill Ball Size for Optimum Grinding
Aug 02, 2013Based on his work, this formula can be derived for ball diameter sizing and selection: Dm = 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill
Key considerations when selecting a mill lining system
Jan 27, 2020Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% 40% of mill chamber volume. To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill's contents.
