There are several types of milling equipment used in the pharmaceutical industry. We have: Ball mills The ball mill consists of a hollow cylindrical/drum that is rotated about its axis. Inside the cylinder, there are small metal balls. The powder is fed inside the ball mill, and as it rotates the balls impact the bulky raw material.

The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell. Optimization Of The Ball Mill Processing The capacity of laboratory ball mill is 5 kg. It constitutes of a double-jacket cylinder, 0.25 m in dia-meter and 0.31 m in height and a stirring group.
Get Price WhatsAppPrinciple of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.

Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance.

Bead Mill - Working Principle. The bead mill consists of a horizontal grinding chamber, which in turn houses the shaft and agitator discs. The chamber is filled with zirconium grinding media and the material leakage is prevented by the double acting mechanical seal.

The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition. Ball mills have the advantage of being self-contained so operators are not exposed to the product being milled. Ball mills cab be used equally well for wet or dry grinding.

mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.
