Such mills normally have integrated classifier. This means plant design is more compact / simple in comparison to ball mill / classifier circuit. On the other hand fineness is limited. Agitated vertical mills. They have much higher specific grinding energy and from there are for production of finer products than conventional ball mills.

Generally, a maximum allowed ball size is situated in the range from D /18 to D /24.
WhatsApp: +86 18203695377Ball mill: Ball mills are the most widely used one. Rod mill: The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon.
WhatsApp: +86 18203695377The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where ...

WhatsApp: +86 18203695377For one, the ball charge and tumbling motion of a Bond mill is inefficient in this range. Also, screening well at 500 mesh is not easy. Many people overlook the impact of screening on the Bond results but the impact can be significant. The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons.
