2. Modes of size reduction: Cutting: The material is cut by means of a sharp blades Eg : cutter mill Compression: In this mode material is crushed between roller by the application of pressure Eg : roller mill Impact: This involve the operation of hammer/bars at high speeds. When a lump of material strikes the rotating hammers, the material splits apart.
1 Introduction Size reduction is an important unit operation in pharmaceutical dosage form design and can be defined as the process of reducing the size of pharmaceutical materials by mechanical methods.
The ball mill is a very noisy machine, particularly if the cylinder is made of metal. Applications: Large ball mills are used to grinding ores prior to manufacture of pharmaceutical chemicals. Smaller ball mills are used for grinding of drugs or excipients or for grinding suspensions. Variants of Ball mill. Hardinge mill = Conical end cylinder
Pharmaceutical Engineering: Size reduction by Parag Jain. ... Construction: The ball mill consists of a cylindrical container. The length of the cylinder is slightly greater than its diameter which is partially filled with balls made from the same material as that of cylindrical vessel. The cylindrical vessel is mounted on a metallic frame and ...
BALL 1. PREPARED BY: AMARESH MANNA BALL MILL. 2. It is efficient tool for grinding many materials into fine powder. There are two types of grinding, the dry process and wet process. A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective ...
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). Construction:
The output of a pharmaceutical hammer mill varies broadly. Normally, the size of the particles depends on the sieve variation. These hammer mills may have over 12 different types of sieve meshes. Pharmaceutical materials that enter the systems are reduced to very small particles due to the rotating hammers. The basic working steps are as follows:

Mechanochemical technique aims to strike a balance between defect formation via ball milling and size adjustment of a solid grain to nanoscale (<1000 nm) (Ullah et al., 2014).During the process, a highenergy mill is employed and a specific powder charge is placed along with a milling medium (Lin et al., 2017).The kinetic energy generated during the motion of moving balls is applied to the ...
The following equipment is in regular use for dry grinding pharmaceutical materials: edge and end runner mills, hammer mill, pin mill, and ball mill. The fluid energy mill is becoming widely used for the production of superfine powders. The ball mill and the colloid mill are used for wet grinding and the production of liquid dispersions.
Introduction: Size reduction is a fundamental process in the pharmaceutical industry, as it plays a crucial role in preparing drug formulations. One of the widely used methods for achieving size reduction is the use of a ball mill.

Mechanical stress induced by unit operations such as milling could affect the integrity of the material. The purpose of this study is to investigate the effect of milling on pharmaceutical cocrystals and to compare the performance of ball mill and jet mill, using caffeineglutaric acid (1:1) cocrystal as the model compound.

A fluid energy mill is also known as a pulverizer, micronized, or jet mill. It is used for fine grinding and close particle size control. The reduction of the particles takes place by the attrition and impact mechanism by the air or inert gas introduced through the nozzles present in the chamber. This mill is mainly used to grind heatsensitive ...
