· The difficulty in determining whether such a relationship exists is that the specific energy does not just depend on ore competence but also factors such as feed size, ball load, aspect ratio, whether the mill has a pebble crusher or not and whether the mill is in closed circuit or not. Thirtysix data sets from 24 different operations were therefore analysed to determine what the ...

specific energy (Ecs). The equation used for describing the relationship between the t 10 and Ecs is given below. t 10 = A ( 1 e ) (1) The specific comminution energy (Ecs) has the units kWh/t and is the energy applied during impact breakage. As the impact energy is varied, so does the t 10. Higher impact energies produce higher values ...

Scale‐up of power consumption in agitated ball mills ...
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 mills in absence of grinding beads. In addition, tests ...
