Size Reduction
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 ...

Ball Mill | Baking Processes
What is a ball mill? A ball mill is a size reduction or milling equipment which uses two grinding mechanisms, namely, impact and shear. 1 Unlike other size reduction equipment, such as breakers and jaw crushers, ball mills are capable of producing powders and particulate materials of mean particle sizes within the 750 to 50 micron (µm) range.. Ball …

Ball Mill
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.
Size Reduction
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).
