Magnetic separation takes place after each stage of grinding, the ball mills are in closed circuit with cyclones, the final product is ground to 90 – 92 minus 279 mesh and contains 65 iron with a 5,2 silica. the final concentrates are then pelletized in an allischalmers gratekiln system.
In these cases, the feed to the ball mill may be from 10 to 100 mesh or even finer. where the finished product does not have to be uniform, a ball mill may be operated in open circuit, but where the finished product must be uniform it is essential that the grinding mill be used in closed circuit with a screen, if a coarse product is desired.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. different materials are used as media, including ceramic balls,flint pebbles.
The ball mill consists of the mill base and the mill jar. there's one more important component to a ball mill, though: the media. the balls of heavy material which fall upon and crush the chemicals are called the milling media.

However, the most significant aspect is how much of the 90 is on the 325 and 270 mesh screens: 26. the 45 grade only has 2.6! this is a huge difference and shows the value of using the finer material. it would take a typical ball mill hours to make this difference. we thought we were using 200 mesh silica until we did this test.
For a rod mill–ball mill circuit, do not apply a mill diameter correction for the ball mill. if the rod mill feed is produced by open circuit crushing, use a factor of 1.2 for the rod mill stage only. if the rod mill feed is 80 passing 12 mm or less (e.g. from a closed circuit crusher) do not apply a rod mill.
If you can see ball motion of your ball mill. best way to determine the critical rotation speed is to see the actual video of ball motion. (cascading, cataracting and rolling).
