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.

Jan 15, 2015· Page 1 of 2 - How many balls for the mill? - posted in Tools and Tooling: Hi there, Ive got a 2L ballmill and I usually make around 100g of BP at once.So, if I use lead balls, how many do you suggest me to put in there? I can also choose between 12.1mm and 15.1mm diameter (15/32th or 19/32th).The weights are 10.4g and 20g per ball. Best Regards

Jul 01, 2003· Every mill is limited in cooling surface area and therefore limited to the maximum amount of energy that can be used for grinding. This dictates the installed motor power for a mill. The nominal energy density of a mill is the available energy per volume of milling chamber. Energy Density = Installed Motor Power (kW) Mill Chamber Volume (liters)
