Ball Mill Capacity and Power Consumption Relationship to Mill Speed
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. Therefore T = f6 (F) = f1 (D²)·f7 (υ) tph..................... (12) Indicating again that υ = πDn, and n = c9np/√D, Eq. 13 becomes
