Ventilation Prediction for an Industrial Cement Raw Ball Mill by ... MDPI

In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)".

Electronic ear in SAG mill | Automation Control Engineering Forum

Hi List: 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.
