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.
ZTIC Ball Mill Feature
1The cylindrical mill adopts the driving type edge-driving, center-driving, edge-driving with multi-point meshing, etc; driven by asynchronous motor +reducer +pinion and gear as well as synchronous motor +
air l\clutch + pinion and gear.
2Generally supported by static-dynamic pressure bearing on both ends. Fuuly closed self-aligning 120º osculation rocker bearing is used. Also single or double slipper staic- dynamic bearings can be used. The bush is made by NC machine.
3 The large open gear is designed using AGMA standard, Equipped with reliably sealed gear housing and grease ahtomatic spraying lubrication system.
 The shell is key part of a mill. Carry out finite element analysis on it with computer to ensure the reliable operation;
4 The shell is automatically welded, ultrasonic inspected, wholly annealed and machined by large special machine tools on one chucking; there special seal on static-dynamic connection parts , ch as feed and discharge hoper, trunnion, etc, to prevent oil and slurry leakage;
5 The liner is of wear-resistance material mad by our company, wich has been specially heat-treated, with high hardness and long service life. Also other wear-resistance casting or rubber liner can be used;
6 There are slow speed drive for medium and large mill;
7The high and low pressure lubricating station is equipped for medium and large mill;
8The control and protection system is controlled by PLC.
