4. How do you adjust particle size in your mill? Particle size is adjusted primarily by a change in feed rate. When the rate is reduced, finer particles result because there is more energy available per particle to accelerate the particles and the entire fluid mass. Collisions become more violent and pressure gradients become larger.
