The image above represents shaft power. Two essential parameters are needed to calculate shaft power: mill capacity (Q) and specific power of mill (E).
The formula for calculating shaft power:
P = QE
Where:
P = Shaft Power
Q = Mill Capacity
E = Specific Power of Mill
Let’s solve an example;
Find the shaft power when the mill capacity is 20 and the specific power of mill is 24.
This implies that;
Q = Mill Capacity = 20
E = Specific Power of Mill = 24
P = QE
So, P = (20)(24)
P = 480
Therefore, the shaft power is 480 W.
Calculating the Mill Capacity when the Shaft Power and the Specific Power of the Mill are Given
Q = P / E
Where;
Q = Mill Capacity
P = Shaft Power
E = Specific Power of Mill
Let’s solve an example;
Find the mill capacity when the shaft power is 24 and the specific power of mill is 6.
This implies that;

P = Shaft Power = 24
E = Specific Power of Mill = 6
Q = P / E
That is, Q = 24 / 6
Q = 4
Therefore, the mill capacity is 4.

Calculating the Specific Power of Mill when the Shaft Power and the Mill Capacity are Given
E = P / Q
Where;
E = Specific Power of Mill
P = Shaft Power
Q = Mill Capacity
Let’s solve an example;
Find the specific power of mill when the shaft power is 36 and the mill capacity is 12.
This implies that;
P = Shaft Power = 36
Q = Mill Capacity = 12
E = P / Q
So, E = 36 / 12
E = 3
Therefore, the specific power of mill is 3 W.
