Mill type overview three types of mill design are common the overflow discharge mill is best suited for fine grinding to 75 106 microns; the diaphram or grate discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns; the center-periphery discharge mill has feed reporting from both ends and the product discharges .
Discharge plenum model is also included to simulate the pulses the output from the model includes instantaneous pressure and flow information along with the the model includes four control volumes (central scroll pocket the twin adjacent pockets and the hub) valve multiplied by the force area subjected to this difference the .
Sag mill trommel screen mineral processing metallurgy a sag mill trommel screen lets you control the true discharge size of your sag mill or the transfer size to the downstream ball mill circuit a well sized trommel should not let rocks pass to the ball mill if they are to be more than say 58 or 16mm in the image case below strangely enough metso is the mill shell liner and discharge grate .

Porting a load of 1000 lbs will require a turning force at the idler roll periphery of from 05 to 07 lbs to overcome the bearing friction the milling or churning of the grease in the bearings and the bearing seals will require additional force this force however is generally independent of the load on the idler roll.
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent it is especially difficult to teach mill .
