A three-roll mill is used mostly for dispersion, but does some grinding as well. It uses three rollers of different speeds and directions to cause the sheer force between them to disperse and grind particles. The three-roll mill is used to disperse material within a media, which is usually some type of semi-viscous material such as cream.

A high‒speed disperser is highly efficient and in many cases all that is needed to achieve the required dispersion result. If however, a finer dispersion result is desired, dispersion becomes a two step process, with the disperser used for pre‒dispersion, followed by further milling in a bead or basket mill. Applications for disperser include:

sure increase in the mill leads to higher throughput rates; and the device is easily disassembled and cleaned. Mild dispersion versus real comminution The bead mill reduces material to nanoparticles in one of two ways — mild dispersion and real comminution. The difference between mild dispersion (disaggregation or
Theory and Practice for . Jar, Ball and Pebble Milling . Types of Mills . Ball and Pebble Mills: The expressions "ball milling" and "pebble milling" are frequently used interchangeably. Usually, however, a ball mill is referred to as one that uses steel balls as grinding media, while a pebble mill is one that uses

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.
Smaller and/or harder beads (e.g. zircon oxide or steel) can also improve the dispersion result. Further, the bead charge can be increased to about 80%. In order to operate the bead mill economically, dispersion should be made with as much solid matter as possible. If after the dispersion there is some flocculation, a suitable dispersing aid ...
