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

Ball mill for iron ore grinding in Malaysia quarry mining. SBM has developed numerous of different Ф series ball mills for various ores grinding. Especially for Malaysia quarry mining our ball mills have become the core iron ore grinding mill. The SBM Ф series ball mills have a
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill
A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below
Investigation on the particle size and shape of iron ore pellet feed using ball mill and HPGR 909 areas of 500–1600 cm2 g-1. The concentrate must therefore be re-ground in order to prepare suitable pellet feed. High pressure grinding roll (HPGR) and ball mill are the most widely used
Dec 24, 2017 A section of a commercial ore grinding operation is shown in figure 1. This section consists of 13 rod mills and 26 ball mills, which are on the left of the picture. Each ball mill weighs more than 150 st, processes 85 st of ore per hour containing approximately 1,000 lb of copper and consumes approximately 95 lb of grinding balls during that time
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore
