Size Reduction and Separation

Subtopic: Size Reduction and Particle Analysis

Question Statement:

According to Kick's Law $E = K_K \ln(L_1 / L_2)$, energy required is proportional to the reduction ratio. If Kick constant is $K_K = 10\text{ kWh/tonne}$ and size reduction ratio is $L_1 / L_2 = 2.718$ (so $\ln(2.718) = 1.0$), the energy consumed $E$ in kWh/tonne is:

Answer Key:

10

Step-by-Step Solution & Explanation

$E = 10 \times 1.0 = 10.0\text{ kWh/tonne}$.
