My company using ball mill as the second stage of grinding usually experiences high mill mass. we are therefore forced to grind out in order to reduce the mill mass. We also experience excessive overflow of materials/feed entering the ball mill from the feed launder. What could be the causes of these problems we are experiencing.

The average ball consumption for mills in closed circuit has been plotted in Fig. 15 for steel balls and for cast composition balls. Enough data are not available to plot curves for hard and soft ores, and individual figures will vary considerably from the average of the curves, which are given merely a guide as to what may be expected and also to show the increased consumption with finer ...

Alumina Balls and Satellites. Union Process is the one source for 90%, 94%, % and % alumina media. 90% alumina is available in satellites and rod/cylinders. 94% alumina balls have excellent wear resistance with higher impact strength to save running costs with less contamination. They have great wear rate generally better than 90% or 99 ...

continuous ball mills. In an experiment conducted using a wet laboratory continuous ball mill filled with pebbles, cylinders and balls of equivalent volume and a 95% calcite feed combined with a 5% quartz, ball load, density and shape were varied. It was shown that decreasing the ball load by by weight also decreased the residence time by 40%.

The most common Ceramic balls available are Alumina Oxide (Al2O3), Silicon Nitride (Si3N4) and to a lesser extent Zirconium Oxide. These balls differ in properties and benefits. Silicon Nitride offer very high resistance to wear and abrasion and weigh 60% less than steel. They are also resistant to corrosion and are anti magnetic. These balls ...

Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm. An empirical model from "Emerging Trends in Mineral Processing", 2005, is ...

This phenomenon is being exploited to improve mill productivity and ball consumption in the Henderson SAG mills. The opposite effect occurs in Climax 3 and 4 m ( and 13 ft) ball mills. These grind less than mm ( in.) ore that requires 76 mm (3 in.) top size balls.

I assume you are referring to a ball mill, since cyclone discharge recycle normally goes back to ball mill feed. I am less versed in ball mill grinding. Ball mills break rock by compression fracture, while SAG mills predominantly break by shear. Some compression fracture does occur, but, it is not the major comminution mechanism.
