High Energy Vibratory Ball Mill Mixer (Mixer/Mill 8000M, Spex) with different kinds of jars (Hardened stainless steel and zirconium oxide).

Planetary Mills are ideally suited for fine grinding of hard, medium-hard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.

2. High machine noise level especially if the hollow cylinder is made of metal, but much less if rubber is used. 3. Relatively long milling time. 4. It is difficult to clean the machine after use.

F. Delogu, G. Mulas, in High-Energy Ball Milling, 2010. 5.2 Fundamentals of mechanical alloying processes in ball mills. A ball mill is a relatively simple apparatus in which the motion of the reactor, or of a part of it, induces a series of collisions of balls with each other and with the reactor walls (Suryanarayana, 2001).

The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry.

Milling was then performed in 80% ethanol for 30–120 minutes using a high-energy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intra-fibre swelling.

The SHMM was developed in our laboratory and generates amorphous starch by changing starch crystallinity due to the applied shear force and heat energy. Milling by an SHMM of tapioca starch can be conducted at slightly lower temperatures than that used for rice flour milling (typically 120 °C) [9, 10, 12] because tapioca starch has a C-type ...

The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm.

The High Energy Ball Mill Emax combines high-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism. The grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation.
