Technical efficiency is the basic productive capacity of an organization or economy. Allocation efficiency is a strategy that uses that capacity efficiently. For example, an organization that can produce 900 pencils per hour isn't efficient if those pencils are produced in a color that no customers efficiency of an economy or ...

If the rod mill feed is produced with open circuit crushing, apply a inefficiency factor to the power calculated for the rod milling stage only. If the rod mill feed will consistently be 80% passing ½" or finer, such as produced with closed circuit crushing, do not apply a rod mill inefficiency factor.

This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.

Since the energy required to produce such a product ranges from 10 to 100 kWh/t in real grinding systems, the calculated energy efficiency would be %. Using a controlled cleavage technique, Gilman (1960) measured the amount of energy required to extend a crack in various crystalline materials when they are cleaved by elastic deformation.
