The image above represents energy input. To calculate energy input, three essential parameters are needed and these parameters are Constant (K), Feed Size (D1) and Product Size (D2).
The formula for calculating energy input:
E = K(1/D2 – 1/D1)
Where:
E = Energy Input
K = Constant
D1 = Feed Size
D2 = Product Size
Let’s solve an example;
Find the energy input when the constant is 10, the feed size is 2 and the product size is 8.
This implies that;
K = Constant = 10
D1 = Feed Size = 2
D2 = Product Size = 8
E = K(1/D2 – 1/D1)
E = 10(1/8 – 1/2)
So, E = 10(0.125 – 0.5)
E = 10(-0.375)
E = -3.75
Therefore, the energy input is -3.75 J.
