Scale‐up of power consumption in agitated ball mills

Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated.

Comminution and transport behaviour in agitated ball mills

Jan 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.

Accurate Scale Up IsaMill™ Advantages Isamill

Power scale up is accurate because power is measured as power consumption at the agitator shaft to determine the specific energy requirements and size the mill; and PSD scale-up is accurate because of the horizontal IsaMill™ layout, which eliminates any short circuiting, and the classifying action of the product separator.

Ball Mill Scale Up Paul O. Abbe®

The rule of thumb for mill scale up is approximately 1-(√D/√d) where d is the diameter of the smaller mill and D the diameter of the larger mill. So going from a 12" lab scale mill to a 24" mill, 1-(√24/√12) = 0.4, so the larger mill may perform as much as 40% more efficiently.

Scalability of Agitated Bead Mills 2014-04-01 PCI Magazine

May 01, 2014· Scale up of agitated bead mills is possible. The scale up method is based on the product and the mill type used. P 0 is the idle power (power consumption of the empty mill); and .mis the throughput rate of product through the mill. E m can now be easily calculated from the measured data from a pilot mill.

The effect of processing parameters on energy consumption

grinding media (steel balls) on power requirements and energy consumption of a ball mill. With constant mass of the steel balls (20, 30 and 40 kg), the agitator shaft speed was increased from 10 to 100% of the maximum speed, which corresponds to a speed of 50 rpm. The power consumption (W) was recorded upon which milling energy consumption
