  • Size reduction of material using ball mill - Labmonk

    BackgroundProcedureReferencesThe ball mill works on the principle of impact between the rapidly moving balls and the materials .Both the balls and the sample are enclosed in a hollow cylinder. At low speeds the ball rolled over each other and attrition takes place.1,2At critical speed the centrifugal force just occurs as a result the balls are picked up by the mill wall and carried nearly the top where that break contact with the wall and fall to the bottom to be picked up. In this manner impact stress will also be induced and the size reduction mad
