grinding stage ball mill

IndustrialBall Millsuse horizontal rotating cylinders that contain thegrindingmedia and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the “toe” of themillwhen the force of gravity exceeds friction and centrifugal forces. Particles are broken in the toe of themillwhen caught in the collisions between thegrindingmedia themselves and thegrindingmedia and themill…

autogenous and semi autogenous mills flsmidth

Semi-autogenousgrindinguses a minimalballcharge in the range of 6-15% while autogenousgrindinguses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of themillcharge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill
