Energy Considerations In Compressive And Impact Crushing

Aug 01, 2008 If it is so that impact or compressive crushing is a more energy efficient method than grinding, it will be tempting to reduce the size as much as possible in the crushing circuit that precedes the mill. A common objective for a crushing plant is to maximise the tonnage of, let us say 12.5 mm.
