EXPERIMENT
DISCUSSION In this experiment, we are going study the concept of size reduction using ball mill using coarse sugar. Ball mill is a grinder that has a slow rotating, horizontal steel cylinder that are half filled with ceramic balls. The observation is done by using two table of data which is sieve fraction of coarse sugar before and after ball milling.

Ball Milling | Material Milling, Jet Milling | AVEKA
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 ...
