What Determines The Screen Size In Grinding In A Mill ...

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

How is Finished Particle Size Determined ... - Schutte ...

08/08/2013· Finished particle size is determined by a combination of screen size, rotor speed, and the size and number of hammers. Material must remain in the grinding chamber until it is able to pass through the screen covering the hammer mill’s discharge opening. Optimal screen size is determined by the desired finished particle size, and the properties of the material being processed.
