The Ball mill drive sets the milling drum into slow rotation and the bed of milling media is thus activated, the balls are lifted and then impact back against the bed. Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out.
Wet pan mill is a good best replacement for the ball mill, it is very popular adopted in the grinding circuit of the middle, fine particle processing plant. Statistically, over 80% of gold mines are placing pan mill s in an important position. Materials: silver, gold, iron, zinc, lead, antimony, tungsten, etc. Types of pan mill

Is this a new mill with an ungraded ball charge? All the balls could be wearing out at the same time (if it is ball chips being rejected). Are you maintaining ball charge at a set volume or using mill power draw to maintain the charge? Have you inspected the grate to make sure it is still in good shape? Regards. Todd
to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between – % which is lower than mill ball filling percentage, according to the designed conditions (15%). In addition, acquired load samplings result for mill ball filling was %.

The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the ...
