How is Finished Particle Size Determined? Schutte

Aug 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 ...
