The result of Kwades investigations and work is that the milling efficiency is a product of stress intensity and stress numbers, and the best milling efficiency is achieved by selecting grinding media size, denisty of grinding media, and mill speed to approach an optimum
Improved energy efficiency of sugar mill operations to a maximum possible extent is a pre requisite for building high efficiency grid connected cogeneration power plants. Reduced captive steam and power consumptions enhance bagasse availability for extra power generation and for extending their period of operation beyond the crushing season.

Mechanical efficiency. Mechanical efficiency, measure of the effectiveness with which a mechanical system performs. It is usually the ratio of the power delivered by a mechanical system to the power supplied to it, and, because of friction, this efficiency is always less than one. For simple machines, such as the lever and the jackscrew,

Efficiency is important for windmills, because the entire cost is in the technology, not the source of energy, which is wind. The most significant factor determining the efficiency of windmills is the number of blades. This is because more blades capture more energy. Large windmills must use few blades due to stress on the metal.

The extremely low wear rate of the mill parts provides an increasing range of interesting new applications. On the other hand, jet milling requires a high energy input, which often cannot be justified by the final product value. It is therefore of critical importance to provide improvements to this process to achieve a higher energy efficiency.
