ball mill size reduction micrometer BallRodmillLiterature TheBallRodmillsare meant for producing fine particlesize reductionthrough attrition and compressive forces at the grainsizelevel. They are the most effective laboratorymillsfor batch-wise rapid grinding of medium-hard to very hard samples down to finest particle sizes.
Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the application of planetary ball mills has extended to mechanochemical approaches. Processes inside planetary ball mills are complex and strongly depen
ceuticals etc. Ball mills operated in dry or wet mode are frequently used for fine miling since they are able to handle rather coarse feeds several millimetres reducing the particle size down to 10 micrometer with reasonably low power consumptions3.

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.
Ball mills are usually designed with a maximum reduction factorratio of 601 although it is possible to achieve reduction ratios of up to 701. The electric drive for a ball mill should be able to handle loads where the ball mill is charged by up to 45 with balls.
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion the particles in between the media and chamber walls are reduced in size by .
