Comparison of Laboratory and Iron Ore Mill Data Discussion Conclusions Ore grinding is a major cost operation for the mineral processing industry. The U.S. mining industry consumes more than 400,000 st of grinding rods, balls, and mill liners in wet grinding operations at an annual cost of $300 million a significant portion of the milling cost.

Ball mills are built in sizes ranging from small laboratory mills to a present maximum of 12 ft. diameter by 12 ft. long, the latter requiring close to 1000 hp. Liners are usually of manganese steel, of chrome steel, or white iron, 3 to 6 in. thick. Corrugated and shiplap construction is commonly used to increase the grinding action. Conical Mills

2. More cost-effective to use pebble mills instead of ball mills (Eg. Swedish iron mines). The only variable-speed "ball mills" I can think of would be the ones at Sino Iron, and they are variable-speed because the mills are so big that the only drive technology they can use is gearless, and gearless drives are inherently variable speed.

What did the ball mills look like and what design? By chance we came across a video in which the author came up with a very bold and interesting theory about this topic. In short, according to the author, many of the cannons (especially large calibre – diameter of 100mm and above) are actually ball mills for grinding iron ore.

Side note: If you're grinding something that has the same primary and secondary outputs, you're probably better going with whatever increases main output %, as the percentages are multiplicative (ie. Main out is 100%, with a 150% grinding ball, you'll get 50% more primary, whereas if the secondary is 10%, a 150% increase still only makes it go to 15%)

The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions, with about 70% solid mixture in water. This procedure maximizes ore production and minimizes power consumption.
