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.

The C/P atomic ratio derived from the XPS intensities decreases upon increasing the ball milling time from 2.01 to 1.25 for the two P/C-composite materials ball milled 2 and 54 h respectively. The C/P value after 54 h of ball milling is in close agreement with the EDS value and the expected 1.1 molar ratio.

Mill (grinding)Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g. via a hand crank) working animal (e.g. horse mill) wind or water ().

Pin Mill Description operating principles advantages
The mill product leaves by centrifugal forces to the periphery and is then collected or further processed. This method of milling is most likely to produce materials in the micronized regime (as less than 40 micrometres) and with uniform product size. Cooling of the rotating disks is a useful way of removing heat from the mill.
