grinding media size distribution in ball mill

Ball milling is a type of grinder used to grind materials into fine powder. Ball mills rotate around a horizontal axis, partially filled with the coarse salt to be ground plus the grinding medium. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages.

In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.

The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).

Jun 18, 2019· The ball mill has a low rotation speed, a large media size, and a large radial velocity gradient along the pin. Therefore, the grinding efficiency is lower and the particle size distribution is wide. Therefore, the ball mill is gradually be replaced by the bead mill, and is now only used for hard Alloy, ferrite grinding or pre ...

Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.

The size reduction that follows will depend on: 1. the charge characteristics (mass, volume, hardness, density, size distribution), 2. the characteristics of the grinding media (mass, density, number, ball size distribution), 3. speed of rotation of the mill, 4. slurry density when wet grinding is adopted.

The ball size distribution (BSD) in a mill is usually not known, as the measurement of the charge size distribution requires dumping the load and laboriously grading the balls into size classes. Fortunately we had one set of data as discussed below.

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".

According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times.
