Size reduction is a very inefficient operation, and only 1 to 2% of input energy is utilized for size reduction, and the remaining energy is lost in the form of either heat or sound. Most of the energy applied for size reduction is absorbed by the equipment itself; therefore, the size reduction process is considered as inefficient.
