medium-scale) to pharmaceutical production (largescale) was investigated. Wet ball milling in a dual centrifuge (DC) (10–100mg API, 40 samples in parallel) was used to identify stable nanoformulations. In addition different sized agitator bead mills were used for scale-up to industrial scales. DC-and small-scale agitator milling (AM)
Apparatus: Ball mill. Sieve set. Weighing balance. Sample. PROCEDURE. Kept 100 gm of rice and charge it to series of sieves to get pregrinding size distribution. Continuous sieving for 10 minutes. Weigh the mass of rice retained on each sieve. Load the rice into ball mill along with metal balls. Run the ball mill for 30 minutes at a speed of 1

Ball Mill Principles Ball mills, sometimes referred to as pebble mills or tumbling mills, are milling machines that take the form of cylindrical vessels containing balls mounted on a metallic frame that can revolve around its longitudinal axis. Depending on the feed and mill size, balls with varying diameters occupy 30
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.
Tube mills. Rod mills. Ρebble mills. Ball mill. The term “ball mill” is usually applied to a mill in which the grinding media are bodies of spherical form (“balls”) and in which the length of the mill is of the same order as the diameter of the mill body; in rough figures the length is, say, one to three times the diameter of the mill

At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.

Pharmaceutical companies work with small compound particles. They seek to separate chemical compounds to get to the smallest state of the compounds. That is why the colloidal mill is important in the pharmaceutical manufacturing industries. This is a machine that is used to reduce the size of particles of solids that are suspended in a liquid.

BALL MILL Construction The ball mill consists of a hollow cylinder rotated on its horizontal axis. Inside the cylinder balls or pebbles are placed. Cylinder: Cylinder may be made up of metal, porcelain or rubber. Rubber reduces the abrasion. Diameter of the cylinder ranges from 1 to 3m in pharmaceutical practice. Balls:
Ball milling is a technique that is utilised by the pharmaceutical industry for granular size reduction of drugs or excipients. There are many reasons to mill particulate materials. Very often, the milled product is required to have a specific surface area, or it might be a process requirement that the fragments are consistent in shape

26 The grinding procedure took place using a laboratory-scale vibrating ball-mill for 10 min at 30 Hz. The ground reactants were then mixed with ZrOCl 2 ·8H 2 O in a water/acetic acid mixture (5
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

8.3.2.2 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 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Conclusion. The Mixer Mill MM 500 control is a true world first: the first high energy laboratory ball mill that enables the user to control and monitor the temperature throughout a grinding process.
