subject: Reasons For The Over-milled Of Minerals [print this page] The grinding equipment is single. The grinding equipment is single.
Since the mill to its strong role of selective grinding workers optimistic about the dressing, but the presence of hard grinding particles gave promote the application created a significant obstacle. This is because the broken system oftreatment of hard grinding particles of iron into the very strict restrictions onnon-ferromagnetic metal removed is difficult to do, the ferromagnetic metal is difficult to separate magnetic minerals, stone crushing system is difficult to run, so that self-the mill'sproduction capacity can not improve, can not meet the dressing requirements of production, thus limiting the promotion and application of self-mill in the mountains ofmagnetite. Accurate in addition to the iron equipment, stone crushing system to relax therestrictions on the iron boundaries and directions for future research.
Ore grain size too wide.
The grinding process are generally two in the choice of grinding media is very difficult.Targeted in particular the choice of grinding media is difficult to do targeted grinding can not be achieved, resulting in some of the mineral to be excessive wear caused great difficulties to the sorting operations. Blind pursuit of short process is also an important factor in this situation. This is a misunderstanding, the direction of our research is to increase the number of segments, grinding ore grain size and narrow, making it thechoice of grinding media to more targeted, and by improving the efficiency of each millore to improve the overall efficiency of the grinding, so that consumption has not increased.
Grading operations to be further improved.
Our magnetite concentrator applications grading equipment spiral classifier, hydraulicscrew, high-frequency fine sieve. Spiral classifier most of the concentrator has been in the application of iron ore concentrate price market in recent years to improve on thegrade of the rate of increase, prompting people to pay more attention to improve thegrade of iron concentrate grading efficiency of the spiral classifier reverse theshortcomings of the rich class has been paid special attention to people, so in some of the concentrator has been some other device instead, will eventually be eliminated.
