Amit 135 Lesson 6 Grinding Circuit Mining Mill

Agsag 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 agsag milling can often be accomplished with fewer lines than in a conventional rod millball mill circuit a diagram of types of agsag

Electronic Ear In Sag Mill Automation Control

Aug 25 2004 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 420ma signal or something else in order to determine if the ball is crushing the mineral or the mill lining
