What's the Difference Between SAG Mill and Ball Mill ...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Introduction to Cyclones

A cyclone is a device that uses centrifugal forces to classify solid particles, in a liquid stream, by size and/or density. What does a Cyclone do? If a cyclone is fed with a sand and water mixture containing a range of particle sizes, most of the fine sand will report to the overflow (the top of the cyclone), together with most of the water.
