What's the Difference Between Ball Mills and Rod

The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.

Do you know that: how to finger up the charge

17-11-2011  In rod mills, the charge is swollen by particles of feed which separate the rods. If the mill is shut down immediately after the feed is shut off, the charge level will be greater than if the mill had been “ground out” prior to shutdown. Because of this, rod mills are normally operated with a 32 to 40 percent charge by volume.
