Grinding Media Selection. Grinding Media Selection In order to do a good job selecting media for your mill, you must consider the type of mill being used, and what is and is not important to consider. For this reason, this subject will be broken into two sections: Vertical Mills and Horizontal Mills.
Milling and grinding media are designed for ball milling and the grinding of bulk powder or granular materials into finer powder forms. Ceramic bead, hard metal shot, carbide balls, and other ball-shaped media are used. The hardness of the powder or bulk material to grind determines the selection of the media material.
Selecting a material for grinding media must take into account its resistance to wear, the availability of suppliers and the considered grinding system (ore characteristics, grinding parameters, etc.) A wide array of materials is used to …
Figure 3 depicts the effects of media size on grinding times. From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes.
Grinding Media Selection Guide Union Process, Inc. The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8 to 1. Horizontal mills require much smaller media, as …
The materials used to make grinding media are mostly cast iron or alloy with special processing, followed by ceramics, alumina, etc.; the grinding media gravel used for gravel grinding are near spherical, ellipsoidal, egg-shaped, etc., which are specially made from ore or rock.

Grinding Media is typically a bead of uniform size, shape, and density. The media is agitated in high concentration with a slurry (or mill base) to be ground. In a small media mill a central shaft agitates the media and slurry. Energy is transferred from that shaft to the nearest layer of beads and from that layer to subsequent layers of beads.

MEDIA SELECTION Choice of grinding media depends upon several factors, some of which are interrelated. • Specific gravity. In general high-density media give better results. The media should be denser than the material to be ground. When grinding some slurries, media with higher density may be required to prevent floating. • Initial feed size.

Alumina Grinding Media (sp.gr. 2.8 to 3.9) Available in a range of specific gravities which rises as the alumina (Al2O3) content increases. The grinding media is actually alumina particles held in place by an SiO2 glass phase.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner …
Grinding media density. The range of specific gravity for commercially available grinding media runs from sp.gr. 1.0 for plastics to sp.gr. 15 for tungsten carbide. It makes sense that you wouldn't select a very light grinding bead for a highly viscous system or a very dense grinding bead for a low-solids aqueous suspension. Grinding bead diameter.
