Feb 27, for example, in the s, the largest operating ball mill was 5.5 m in diameter by 7.3 m in length driven by a 4 mw motor. today, ball mills of 5 m plus are commonplace, and 7 m ball mills are currently employed on at least two sites. however, there are several cases where large ball mills have not achieved design capabilities. one example was.
If a ball mill uses water during grinding, it is a ‘wet’ mill. a typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. ball mills may be primary or secondary.
Jan 14, ball mill liners are a major cost in mill operation, and efforts to prolong liner life are constantly being made. there are at least ten wear-resistant alloys used for ball-mill linings, the more abrasion-resistant alloys containing large amounts of chromium, molybdenum, and.
Jun 23, in some operations, grate discharge mills can lead to unscheduled downtime due to grate failure, blockage of grates due to sticky ores or poor design, and increased ball consumption due to high wear rates of grate apertures causing loss of media from the mill. in addition, not all mills.
Nov 26, the biggest characteristic of the sag mill is that the crushing ratio is large. the particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. the calculation shows that the crushing ratio can reach ~ , while the ball mill’s.
