    cles back into the grinding chamber, as shown in Figure 2b, rather than through the hole and out of the grinding chamber. This reduces the mill's grinding capacity. Replace the screen whenever the wear causes the mill's capacity to drop about 15 to 20 percent or product quality begins to deteriorate.

    Screen Design 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 60degree staggered pattern optimise open area while maintaining screen strength.
