The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23%

In wet ball milling, biomass fibers swell with water and hydrogen bonding between nanofibers weaken, resulting in defibrillation of the bundle of nanofibers. In terms of final particle size, wet ball milling is more suitable to reduce the particle size below 1 µm compared to dry ball milling .

When the turntable rotates, the tank axis makes planetary movements, the balls and samples inside the tanks are impacted strongly in high-speed movement, and samples are eventually ground into powder. Various kinds of different materials can be ground by the mill with dry or wet method. Minimum granularity of ground powder can be as small as 0.1µm

The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.

It is used occasionally in small-sized mills in the industries such as the chemical industry and food industry. Ceramic ball mills could be in high or regular density. Regular ceramic balls are often porcelain balls and high-density ceramic balls are more abrasion resistant as they are made with high alumina oxide content.

Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40

The 30 mm ball diameter milling still performed better than the small ball diameters, but the performance for this ball size had decreased for the -2 mm +1.4 mm mono-size feed compared to the bigger -4 mm +2.8 mm mono-size feed. This therefore shows that should the material feed size continue to decrease, the smaller balls will

While it is possible, if not advisable, to allow pieces of 2″ or even 3″ size in a ball mill, it is essential that the feed of a rod mill should be no larger than 1-in. and preferably smaller. For the same reason the ore must be friable ; rods cannot compete with balls in grinding hard or tough material.

The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
