mills have a wide application in biomass size reduction because of their simple design, ruggedness and versatil ity [16]. Fine or especially difficult to grind materials are often best comminuted using highspeed hammer mills with small diameter rotors [3]. High tip speeds result in material striking the outlet screen at steep angles,

What's the Difference Between SAG Mill and Ball Mill

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 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
