AMIT 135: Lesson 6 Grinding Circuit – Mining Mill Operator …

AG/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 circuit.

Electronic ear in SAG mill | Automation & Control …

 · We 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.
