For small ball mill, mill diameter less than 3.6 m, with small dynamic loads, the method of free vibration analysis can be used. this is also call modal analysis.
As an engineer who has experience using fem for the design and assessment of sag and ball mill foundations,now that this approach can be timeconsuming, costly and in some cases not evenope of being accurate if you dont have appropriate geotechnical and manufacturer information.
1. the static load or weight of the mill 2. the dynamic loads imparted during rotation of the ball mill, and 3. the gear interaction loads. in addition, to assessing the magnitude of the loads principia also needed to determine the distribution of these loads on the trunnions sees figurend 8. engineers calculated the weight of the.
Circulating load calculation formula. in practice circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent it may appear strange at first sight that the circulating load betweenill and classifier producing for example 100 tons of finished product per day can be as much as 400 tons or more but this will be.
