### The energy efficiency of ball milling in comminution

Abstract. If the energy to produce new surface by single particle breakage is used as the basis for evaluating efficiency, then the efficiency of ball milling has a more realistic value of about 15% for the comminution of quartz and soda lime glass. In a second approach, comminution efficiency is based on comparing the energy to produce some size

The amount of open area in a hammer mill screen determines the particle size and grinding efficiency. The screen must be designed to maintain its integrity and provide the greatest amount of open area. Screen openings (holes) that are aligned in a 60 degree staggered pattern optimise open area while maintaining screen strength. This method will result in a 40 percent open area using 3.2 mm (1/8 inch)
