Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

Objectives of size reduction Size reduction leads to increase of surface area. Pharmaceutical capsules, insufflations ( powders inhaled directly into the lungs), suppositories and ointments require particles size to be below 60 mm size. To increase the therapeutic effectiveness of certain drugs by reducing the particle size. Size reduction produces particles in narrow size range.

3. The ball mill is very noisy machine, particularly if the casing is of metal, but much less so if rubber is used. 4. Relatively long time of operation. Critical speed of ball mill: The faster the mills are rotated the further the balls are carried up inside the mill and the greater the power consumption and capacity of the mill.
A pharmaceutical development program may use ball mills, vibratory mills, planetary mills, etc. during the initial phase for identifying suitable nanosuspension formulations especially when available drug quantity is limited, whereas wet stirred media mills are commonly used at pilotscale and manufacturing scale [47,59,63]. Wet stirred media ...
A ball mill is an engineering device used to grind metal, rock, and other materials into fine powder. It consists of a horizontal axle, a rotating shaft, and a vertical sifter screen. The horizontal axle is connected to a power source and holds the body of the mill. Ball mill is used: A ball mill uses balls to crush rocks into dust. The body of ...

Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
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 singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.
The Laboratory stirred Ball Mill is mainly used for various grind able materials dry or wet type in Chemical, Pharmaceuticals, Herbals and Catalyst Industries for super fine micron size grinding. A lab stirred ball mill is an crucial device in terms of the rapid, reproducible pulverizing, milling or grinding of a massive kind of materials.
