As noted, particle size reduction in a hammermill occurs as a result of the impact between a rapidly moving hammer and a relatively slow moving particle. The particle breaks and is accelerated towards the screen; depending on the particle size and angle of approach, it either passes through the screen or rebounds from the screen into the rapidly moving hammers again.
