studied include mill rotational speed, ball size, mill I charge and wet versus dry grinding. Breakage rates have been determined experimentally utilizing a SEM—IPS image analyzer. The mineral sample used was acquired from ASARCO's Young Mine which is located in Jefferson City Tennessee. It was a binary ore consisting of sphalerite and dolomite.
· The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.
· Five Popular grinding mills. Nowadays, various types of grinding mills have been developed for certain applications. Of these grinding mills, some mills can grind different materials, but others could be only used for certain specific grinding requirements. Here are five popular grinding mills with high performance for sale. Ball mill
