Oct 09, 2019 · Half-load test run: the filling rate of the medium in the ball mill cylinder is about 20-30%, and appropriate materials and water are given for a continuous test run of 8-10 hours. Full load test: after the half-load test and everything is normal, add enough medium inside the ball mill cylinder (gradually increase the ore amount) and run at

ball mill - an overview | sciencedirect topics

A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, i.e. during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity

grinding mill control - grinding & classification circuits

The rms sound level is inversely proportional to the amount of damping exerted by the slurry. High level, low noise. Low level, high noise. In a SAG mill, most of these conditions are not valid. Speed changes, such that you may get confused by the noise coming from grinding media impacting mill shell superimposed to the standard load noise

ball mill load measurement using self-adaptive feature

Sep 15, 2008 · Ball mill load is the most important parameter optimized in the Ball Mill Pulverizing System (BMPS) in Thermal Power Plant. The accurate measurement of ball mill load is imperative and difficult. The approach based on self-adaptive feature extraction algorithm for noise signal and LS-SVM model is proposed to achieve this purpose

what's causing your high motor current? - plant services

Feb 23, 2018 · A winding with magnetic flux levels at least 10% greater than the original design densities will usually draw higher-than-rated current at full load and will have higher-than-typical no-load current. A method of checking the performance of a “magnetically strong” motor such as this is to measure the exact rpm at full load
