calculate ball mill throughput in sweden

The ball size in a mill has a significant influence on the mill throughput power formula for determining the ball diameter depending on the diameter of the grain size Get Quote Calculate and Select Ball Mill Ball Size for Optimum Grinding

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent It is especially difficult to teach mill

Calculating Ball Mill Throughput The reactivity of the coal Throughput tonshr Grindability Several performance parameters are calculated for the pulverizer train The specific throughput has been calculated at grinding time t 3 min Mill Speed Critical Speed How do you calculate ball mill residence time WikiAnswers

How to Size a Ball Mill Design Calculator Formula Mineral Mar 31 2016 Estimation based on FLSmith Krebs Capacity Correlation Ideally design value should not exceed 13 psi

SAG mill feed sample mass grams The ball mill pinion energy is determined from the Bond the Third Theory of Comminution S dBWI 1102 445 P cs 023 G pb 082 10 P 80 12 – 10 F 80 12 where S dBWI Bond ball mill work index on SAG ground ore kWhton ground F 80 80 passing of SAG ground of the test feed size microns P 80

The SAG mill pinion energy W SDT kWht and SAG discharge Bond ball mill work index S dBWI kWht are then used to calculate the total energy to grind the ore from 80 passing 152 mm to 80 passing the client specified final product size P information along with the ore specific gravity is used to calculate necessary mill sizes and motor power in industrial applications

In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often the ball used in ball mills is oversize “just in case” Well this safety factor can cost you much in recovery andor mill liner wear and

Mill Speed No matter how large or small a mill ball mill ceramic lined mill pebble mill jar mill or laboratory jar rolling mill its rotational speed is important to proper and efficient mill operation Too low a speed and little energy is imparted on the product

Replacing traditional steel cast mill liners with new lightweight composite liners is another way to increase throughput of mills Major gold and copper operations have already started doing this in mills up to 40’ Ø and seen an improvement in the slurry discharge of up to seven percent
