Abstract This work investigated the effect of grinding medium size on the wet milling performance in stirred mills using a combined numerical and experimental approach. Physical experiments were performed in a 1.4L stirred mill with the discs rotating at different speeds to grind aluminium hydroxide powders with different sized glass beads. The results showed that the grinding process followed ...

known that grinding finer than approximately 40 lm will result in overgrinding of fines as well as high media consumption. However, it must be noted that the product size to which a mill can efficiently grind depends on the feed material, the F80, and media type and size. A Vertimill has been used to grind to sizes below 10 lm.[11]

The objective of this dissertation was to investigate how media shape affects grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe, light

The grinding performance is strongly affected by the size of grinding media (Stehr, 1988, Mankosa et al., 1989, Kwade et al., 1996, Bel Fadhel and Frances, 2001). Mankosa et al. (1989) investigated the effect of medium size on coal grinding in a vertical stirred mill. The optimum operating conditions were determined in terms of grinding medium ...

Expectations point to smaller grinding media size providing the greater size reduction for a given energy input (Tüzün and Loveday [12], Stehr [13]). With a smaller ball size, the larger is the number of balls and the larger the ball surface area for contact and abrasion to take place. However, in the experiments performed by Yan et al., the ...
