Ball Mill Design/Power Calculation· The work index Wi should be obtained from test results or plant data Rod and ball mill grindability test results should only be applied to their respective methods of grinding If P is less than 80% passing 70 microns power consumption will be Ball Mill Power Calculation Example #1 A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15
A comparative study on the effects of dry and · Chapman et al 2013 compared the effects of using different circuits HPGR dry rod mill wet and cone crusher dry rod mill wet on the flotation of base metal sulfides They indicated that apart from the grinding environment HPGR could produce finer particles than a cone crusher This difference was higher in the fully dry system Moreover HPGR in the dry environment liberated more
Autogenous Grinding Semi Autogenous · Rod mill grindability tests for Work Index are run at 10 or 14 mesh and ball mill Work Index tests are run at the desired grind if finer than 28 mesh All the data obtained is evaluated and one or more of the following recommendations made The ore makes good autogenous media and pilot plant testing should be carried out since the possibilities for autogenous grinding are very good Ore
TECHNICAL NOTES 8 GRINDING R P KingThese mills exist in a variety of types rod ball pebble autogenous and semi autogenous The grinding action is induced by relative motion between the particles of media the rods balls or pebbles This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition In autogenous grinding machines
