ball mill is suitable for ore dressing, chemical, coal, cement and refractory sectors to operate fine grinding. Bearing-type drive ball mill is a technological changing type, compared with the traditional ball mill: 15% lower operating current and reduce the starting current 50%. Improve the phenomenon of ball concentricity not enough, run instability, current fluctuated, wear serious phenomenon hollow shaft according to the phenomenon of Babbitt burning, downtime, the phenomenon of stopping production. After adopt the rolling bearing, the hollow shaft can continue to use, save 90% lubrication oil, improve the loading of 20%, increase production by 15%, 10% speed increase, each power saving can arrave 20%-30%.
ball mill structure: Contained feeding system, the discharging system, the transmission system(speed reducer, small transmission gear, electrical machinery, electric control) & etc.
Mine Ball Mill Application:
A ball mill grinds ores and other materials to a typical product size of 35 mesh or finer.
The feed to a ball mill is prepared by...
· Single or multistage crushing and screening
· Crushing, screening, and/or rod milling
· Primary crushing and autogenous/semiautogenous grinding
Mine Ball Mill Normal feed sizes:
· 80% passing 1/4" (6 mm or finer) for hard ores
· 80% passing 1" (25 mm or finer) for softer ores
(Larger feed sizes can be tolerated depending
The length to diameter ratio of cylindrical mills range from 1 to 1 through 3 to 1. When the L/D ratio is 2 to 1 or greater, werefer to the mill as a Tube Mill.
The two most popular types of ball mills are
Grate or Diaphragm Discharge Ball Mill
In the discharge end of this mill, a slotted full diameter or partial diameter grate with discharge lifter assembly conveys the material to the discharge trunnion opening. The grate serves to retain balls, tramp, and coarse material. A gradient created between the feed opening and the discharge slots eases the flow of material.
Trunnion Overflow Discharge Ball mill
A trunnion overflow mill has an open discharge end. Material flows through the trunnion as a result of the pulp gradient between the feed and discharge openings. A reverse helix in the discharge trunnion liner retains balls in the mill.
