2012-8-20Almost all ball mills use a form of closed circuit grinding that returns material that is too coarse back to the ball mill inlet while material fine enough to meet product requirements is collected.
Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding.
200 TPD Crushing and Grinding Circuit Feeding Gold. The ball mill is running a 4 ball to feed a carbon leach with a P80 of 74 microns. After watching the 2 videos here below I came up with this idea At 100 operating time the 250 x 750 mm primary jaw crusher should be capable of crushing 300 TPD at a discharge product of 1.
