different liner designs at different mill speed but with constant filling degree (30%). Indeed, as explained previously, at a mill stop, the measurement of ball charge filling degree could be undertaken and will provide the static media charge angle (βstatic = 143°). An online measurement of the similar angle (βdynamic), when the mill is ...

Not "speed" of gravity, acceleration due to gravity. If the acceleration is -9.8 m/s^2 then the speed after t seconds is v= 9.8t+ v0 (v0 is the initial speed and I am taking positive downward) and then the distance traveled is s= 4.8t^2+ v0t. Since the ball is "dropped" the initial speed is 0 so we have v= 9.8t and s= 4.8t^2.

In a ball mill of diameter 2000 mm, 100 mm dia steel balls are being used for grinding. Presently, for the material being ground, the mill is run at 15 rpm. At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations: The critical speed of ball mill is ...
