Question:
Energy requirement is highest for
Energy requirement is highest for
Show Hint
The finer the product size, the higher the energy requirement. Fluid energy mill gives ultra-fine grinding, so it needs maximum energy.

- Jaw crusher
- Rod mill
- Ball mill
- Fluid energy mill
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Energy requirement in size reduction depends on the fineness of the final product.
Coarse crushing needs less energy.
Fine grinding needs more energy.
Ultra-fine grinding needs the highest energy.
A jaw crusher is used for coarse crushing.
A rod mill and ball mill are used for grinding.
A fluid energy mill is used for ultra-fine grinding.
In a fluid energy mill, compressed air or steam is used at high velocity.
Large energy is required to generate these high velocity jets.
Therefore, the energy requirement is highest for:
\[
\text{Fluid energy mill}
\]
