The milling jar is half filled with grinding media or balls from to 1 and as the mill rotates the solids are trapped between the ball and are milled down to as little as 1 micron by the cascading and tumbling action of the ball charge milling jars available in ceramic carbon steel stainless steel rubber lined or polyurethane lined
Read MoreThe first problem will ball mills is that we cannot see what is occurring in the mill the other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results in ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time
Read MorePebble mills are a type of ball mill and are also used to reduce the size of hard materials down to 1 micron or less because of their fairly simple design ball mills and pebble mills are less likely to need costly repairs unlike other crushing or extraction equipment making them an attractive option for businesses on a budget
