    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
