Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...

اقرأ أكثرIn simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being processed. It grinds it up into a compound to make processing easier. You'll find a similar process in sugar cane mills. These steel balls can be 100mm or more in diameter initially. Over a period of time, they wear down.
اقرأ أكثرThe mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill.

اقرأ أكثرA ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

اقرأ أكثرYou may find more information regarding the SAG discharge if you search them as "scats" (broken ball chips). Safety Notes; they result from internal stresses in the balls impact and heat energy in the SAG mill causing a Martensite transformation in the ball (Crystals form in the metal) and they have a potential to rupture with very sharp edges.

اقرأ أكثرThe 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.

اقرأ أكثرTrommels remain widely and often work with the screening of mill discharge streams. Tumbling mill (AG, SAG, rod, and ball mills) discharge streams usually pass through a trommel screen attached to the mill outlet to prevent grinding media scats from reaching subsequent processing equipment, and the case of AG/SAG mills, to extract pebbles to send to crushing stage.
