Scale Up Of Power Consumption In Agitated Ball Mills

Scale‐up of power consumption in agitated ball mills,

The specific energy input is the introduced energy related to the amount of comminuted material. This parameter can be used for mill scale‐up. Consequently, a method had to be found of introducing power into the mill so as to obtain a given specific energy input. For this purpose, stirring tests with purely Newtonian liquids were carried out in absence of solids and hence, without comminution. Mathematical models are presented which describe the power consumption in agitated ball millsComminution and transport behaviour in agitated ball mills,,01-01-1992· Experimental investigations have been carried out with different size agitated ball mills (4-200 l) and different materials (limestone, hard coal, microorganisms). The specific energy input has been found to be the most important parameter influencing the comminution result. A method for scale-up and prediction of power consumption is described.Ball Mill Scale-up Method,16-04-2018· Ball Mill Scale-up by this method is known as collision energy based population balance model. The appropriateness of this model is shown for 38-cm ball mill. Comminution in ball mills account for a significant amount of power consumption in mineral processing plants.MODELING THE SPECIFIC GRINDING ENERGY AND BALL-MILL,ENERGY AND BALL-MILL SCALEUP Ball-mill scale up (Bond’s Law) Data: zBond work index w i zFeed D f and product d size (both 80% cumulative passing) Result: The specific grinding energy w Mill power draw P = wT, where T the mill capacity Mill dimensions (from Tables or charts)Ball Mill Scale Up | Paul O.
