Bond Ball Mill Capacity (Rowland EF) — Web Version
Capacity Q is calculated using Rowland form with ζ = product(EF). Units: D,L (m), ρb (t/m³), J (fraction), φc (fraction), Wi (kWh/t), F80,P80 (µm).
Basic inputs
Operating conditions
Result
Capacity Q = ?
Q is t/h (metric tonnes per hour)
Rowland Efficiency Factors (Ball Mill)
EF1 (dry grinding)
-
EF2 (open circuit)
-
EF3 (mill diameter)
-
EF4 (oversize feed)
-
EF5 (fine product)
-
EF7 (low reduction ratio)
-
ζ = EF1·EF2·EF3·EF4·EF5·EF7
-
Bond specific energy (F80 → P80)
Base W (no EF)
-
