What's the Difference Between SAG Mill and Ball Mill
SAG mill vs Ball mill Crushing ratio 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 ofSag Mill And A Closed Circuit Ball Mill Sag Mill And A Closed Circuit Ball Mill In contrast, mills closed by fine screens are limited to using only the most competent mediaMedia typeThe type of media used in the isamill ranges from effectively free media source including smelter slag and coarse sag mill product, to low cost locally available sands through to more expensive, highsag mill and a closed circuit ball mill
SAG mills (semiautogenous grinding mills) minevik Outotec
SAG milling extends itself to many applications due to the range of mill sizes available They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill SAG mills are also an optimum solution for wet grinding since crushing and screening in theseAG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuitAMIT 135: Lesson 6 Grinding Circuit – Mining Mill
A Review of SAG Circuits Closed with Hydrocyclones
