Hammer mill, ball mill, air-jet mill, pin-mill, and conical screen mill are the commonly used equipment for the milling operation. In these, impact, attrition, and shear compression are the main forces for the size reduction. The selection of the appropriate equipment is mainly based on the desired particle size of the product.

Principle. Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).

Size reduction of material using ball mill. The ball mill works on the principle of impact between the rapidly moving balls and the materials .Both the balls and the sample are enclosed in a hollow cylinder. At low speeds the ball rolled over each other and attrition takes place.
Mechanism follows few modes, those are: 1) Cutting: Material size is reduced by cutting by using a sharp blade. Equipment: Cutter mill. 2)Compression or crushing: Material sized is reduced by using roller. Materials placed in between the roller and crushed. Equipment: Roller mill.
1) Rotary Cutter Mill. Size reduction is a process of reduction of material to smaller pieces to coarse particles or to powder/fine powder. Size reduction process is also known as Comminution and Grinding. When the particle size of solids is reduced by mechanical means it is known as Milling. The size reduction operation can be divided into two ...

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for single-stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits.
Ball milling is used in the pharmaceutical industry to reduce the size of particulate material such as pharmaceutical granules. Dr Alexander Krok and Dr Sandra Lenihan from Munster Technological University, Ireland, have developed a computational approach to achieve optimal, energy-efficient size reduction in ball milling resulting in …

Impact and attrition are the main forces involved during size reduction through ball mill. A ball mill consists of a cylinder, which is filled with 30–35% of its volume by small steel balls and is rotated through motor. ... Homogenization is used as an important unit operation in food, pharmaceutical, and cosmetic industries. The most common ...
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.
The primary objective of a pharmaceutical hammer mill is to reduce the size of pharmaceutical materials. This is crucial in the pharmaceutical industry, as it ensures that the ingredients used in drug formulations are of a consistent and controlled particle size. The following steps accomplish size reduction: a.
