A colloid mill is used in the size reduction of solids and droplet present in suspension or emulsion (Fig. 6.16). A colloid mill consists of a rotating cone (rotor), a static cone (stator), and a feeding unit. The size reduction mainly takes place due to the shearing action in the narrow gap between the rotor and stator. The wear is reduced by ...

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.

The cryogenic size reduction process, also known as "cryomilling", involves exposing the resin pellets to temperatures of -100° Centigrade or lower. These temperatures lead to finer grains, as they make even the most elastic polymers more brittle. ... Jet milling uses high-speed mechanical mills to collide pieces of the resin pellets into ...

Unlike the ball mill, there is no grinding medium is used in the fluid energy mill for the size reduction of the materials. Due to the expansion of the gas in the chamber, temperature in the mill decreases which enables the use of the fluid energy mill for the milling of thermolabile substances (Lachman et al., 1987) (Fig. 8.4).
