The size reduction takes place when the material comes between rotating and fixed blade by a mechanism of cutting. The size reduced material falls on the screen present at the bottom. The vibration of mill helps in moving of product into the outlet. The size reduced material is collected from product outlet.
– States that the energy required for size reduction is proportional to the change in surface area of the pieces of food • E = K R 1 1 D. p. D. f • K. R – Rittinger's constant • For the size reduction of fine powders, in which large areas of new surface are being created, Rittinger's Law fits the experimental data better.

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.

Size reduction is a vital unit operation in pharmaceutical manufacturing that involves reducing the size of solid materials to enhance their dissolution properties, improve bioavailability, and facilitate further processing. It is a fundamental step in drug formulation and is employed in various dosage forms like tablets, capsules, and powders.
The diagram below illustrates the placement of a hammer mill in a typical pelletizing process where the hammer mill is used in the breakdown of oversize pellets. In certain low-energy impact situations where the hammer mill is intended to break down raw material to reach ideal particle size distribution, the hammer mill would simply be placed ...

What is an Attrition Mill? Attrition mills mechanically reduce solid particles through the intense acceleration of particles against one another in a curved or flat grooved surface called a stator. These mills use a high-speed rotor to create centrifugal forces that facilitate the necessary particle interactions.

For large diameter rolls, speed of rolls varies from 50 – 300 rpm. But for small diameter rolls speed rolls are very less. Generally size reduction ratio of these rolls are below 5 (i.e. coarse grinding). The diameter of these rolls and speed between rolls can be varied according to feed size and output rate required.
Advantages of Cutter Mill. 1. It is the best option of size reduction when impaction, attrition, or compaction type milling is not effective especially for tough, fibrous, or resilient materials. 2. It is easy to install, operate, and maintain. 3. The equipment is not expensive. Disadvantages of Cutter Mill. 1.
Conclusion. Size reduction equipment is machinery that crushes and grinds materials to reduce their size. Size reduction equipment typically falls into three main types: impactors, crushers, and grinding mills. The grinding and crushing media in this equipment is usually steel, bronze, and brass.
