Cone milling is one of the most common methods of milling in the pharmaceutical, food, chemical and associated industries. They are typically used for size reduction and deagglomeration or delumping of powders and granules.. Generally used for reducing material to a particle size as low as 180µm (80 mesh) they produce less dust and heat than alternative forms of milling.
Particle Size Reduction - Contract Particle Size .
For extreme fineness requirements Particle Size Reduction Services include the use of air micronisers or batch ball mills with ceramic liners and media for iron free grinding in both wet and dry states. Wet grinding can be followed by filtering and tray drying to produce dry powders after dissagglomeration.

Pulverizer - Wikipedia
The ball and tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as an example size.

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.
