Wear cost – ball mills are always cheaper because the grinding media are un-machined castings and can be replaced without stopping the mill. Plant Capacity: Another consideration is the capacity of the plant – large capacity roller mills are a recent development, and previously a single stream ball mill line was comparable in capital …
SAG mills are often used in conjunction with a ball mill or pebble mill to achieve the desired grind size. SAG mills are primarily used in the mining industry, particularly in the processing of gold, copper, and platinum group metals. On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media.
Herbst et al. (1982) proved the scale-up from 10 × 11.5-in. ball mill to 30 × 18-in. continuous flow mill. In a similar study, Herbst et al. demonstrated successful scale-up from the 10 × 11.5-in. ball mill to 14 × 22-ft. plant-scale mill. Because of number of such studies, this scale-up procedure is imbedded in Moly-Cop Tool's "Ball ...
The drop-ball apparatus can simulate the impact contact behavior between steel ball and particle in the ball mill. The effect of particle size, impact energy, and impact number on the iron ore particle impact breakage characteristics were analyzed to reveal the particle breakage behavior in the ball mill.

sonable to replace, totally or partly, ball milling for HPGR wet grinding after filtering. This substitution makes it pos-sible to shorten the time of iron ore inside a ball mill, the ball mill output grows as a result, and a larger size product is obtained. The grain size required for pelletizing is reached in further HPGR grinding (Fig. 5).
Therefore, the rod mill is mostly used for coarse grinding of the previous period of ball mill, or grinding of brittle materials and materials against overcrushing, such as tungsten and tin ore before gravity separation; and (3) autogenous mill – it refers to the materials which themselves are collided and ground mutually to be crushed when ...
