Electronic ear in SAG mill

25-08-2004We have an application in a SAG Mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill. Our idea is to convert the amplitude and frequency of noise to a 4-20mA signal (or something else) in order to determine if the ball is crushing the mineral or the mill lining.

THE INFLUENCE OF SHELL, GRATE AND PULP LIFTERS ON SAG MILL

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Today's high capacity semiautogenous grinding (SAG) mills expend vast amounts of energy and in doing so consume tons of shell liners and steel balls, while processing ore. The energy efficiency of these high throughput grinding mills can be attributed to the field of breakage and slurry discharge system.

Shell vs Trunnion

03-09-2014Shell-mounted mills with end walls directly above the main bearings are generally stiffer than trunnion-mounted mills. We have checked this by comparing a 26 ft shell-mounted ball mill with a trunnion-mounted mill of equal grinding volume and same diameter. Detailed finite element models of each mill were created.
