This study was carried out in a standard bond ball mill 305 mm x 305 mm size in mineral processing laboratory in the mining engineering department at King Abdulaziz University KSA as shown in Figure 2 Grinding media of steel balls weighing 205 kg has been used The details of the mill charge.
rate of abrasion grinding may be slower than the rate of impact breakage and the two can be brought into equilibrium by decreasing the impact force available through lowering the mill speed Likewise if the circulating load is low and the product too fine even with a high ball charge or mill speed the.
If the quantity of charge is very less then milling balls will start to collide with each other and no milling will take place Ball size depends on initial size of charge and ranges from 10mm.

11TH MILL OPERATORS CONFERENCE 2012 HOBART TAS 29 31 OCTOBER 2012 37 INTRODUCTION Rotary mills have been found to be inef cient when grinding large hard material Single stage balls mills when processing hard to grind large sized material incur an oversize inef ciency problem over and above the Bond oversize feed factor EF4.
Jan 01 2016nbsp018332733 Ball Size at Initial Ball Charge Ball sizes commercially available for charging in grinding mills range from 10 to 150 mm The number size and mass of each ball size used depend on the mill load and whether the balls are being charged for the first time to commence an operation or as replacements for worn out balls.
Of course in this instance the longer the stop the more the mill will rotate away from its maximum angle of the charge with the outof balance torque being lower In this case the deceleration will increase during the stop If the stopping time is too severe adjustments can be made during initial set up using the hydraulic system.
