The energy required for size reduction is proposed by -

Correct option is D

· Size Reduction Laws:
· Rittinger’s Law: States that the energy required for size reduction is proportional to the new surface area created. It is best applicable for fine grinding.
· Kick’s Law: Proposes that the energy required is proportional to the size reduction ratio. It applies to coarse grinding.
· Bond’s Law: Suggests that the energy required depends on the square root of the particle size. It is a compromise between Rittinger’s and Kick’s laws.
