Ball mill - Wikipedia. A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
In addition to high impact SAG mill grinding, media is used in other types of milling such as the finer grind of ball mills, tower mills, vibration mills and regrind mills. Many variables influence the size reduction performance in a mill, including the media size, shape & quality, the properties of the incoming ore feed, the ratio of feed to ...

Grinding materials to a nano-scale is an important aspect of quality control and R&D. AZoM speaks to Dr. Tanja Butt from RETSCH GmbH about the benefits of using High Energy Ball Mills instead of Planetary Ball Mills.
Apr 16, 2021 The limiting reduction ratio is the maximum feed size to the maximum product size (see formula below). R/1=F100/p100 This is the easiest method to estimate the reduction ratio, especially when you don’t have details about the machine.
Sep 01, 2013 As the size reduction ratio increases, the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of 128:1 (Fig. 7d), a 50.8 mm/25.4 mm ball mix at a 13:87 ratio was found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.

Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range 1.56–1.64.
For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball …
