A ball mill is a grinder equipment used in the pharmaceutical industry to reduce the particle size of active and excipient materials. It is also used in other industries such as chemicals, ceramics, environmental protection, medicine, mines, and geology. Ball mills are commonly used in laboratories to grind sample materials to very small sizes.
BALL MILL Principle Th ball mill work on the principle of impact between the rapidly moving ball the powder materiel, both enclose in a hollow cylinder. At low speed the ball role over each other attrition will be predominant mode of action. Thus, in boll mill impact or attrition or both are responsible for size reduction.
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.
In pharmaceutical research and development, various new chemical entities (NCE) are found to be poorly watersoluble. Therefore, solubility enhancement, a key factor for higher bioavailability, is a major challenge in pharmaceutical industries. ... Hammer mill, ball mill, airjet mill, pinmill, and conical screen mill are the commonly used ...
Ball milling is widely used in industry to mill particulate material. The primary purpose of this process is to attain an appropriate product size with the least possible energy consumption. The process is also extensively utilised in pharmaceuticals for the comminution of the excipients or drugs.

Hammer mill is easy to set up (install), dismantle, and clean up. Scaleup problems are minimum provided the same type of mill is used. Various types of feedstock can be handled using a screen of different sizes. Hammer mill occupies a small space. It is versatile,, speed and screen can be changed rapidly.
Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications. Cooling, heating cryogenic grinding.
Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...
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:
