Ball Mill Capacity and Power Consumption Relationship to ...

· The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. n = c9np/√D, the above equation becomes P = f1 (D²)·f5 (πD c9 np/√D) = cs np As a first approximation, the capacity, T, of a mill may be considered as a function of the force acting inside the mill.

Powerbased modelling of singlestage AG and SAG mill circuits

energy consumption is defined as the motor power consumed relative to the shell of the mill ( power at the pinion output) divided by the fresh feed rate in dry tonnes per hour. The simplest models use a single grindability measurement to estimate the specific energy consumption across the whole size range observed in the industrial ...

Optimization of mill performance by using

Mill power Usually, plant operators use mill power readings as an indior of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
