Among those styles, the functionality of a hammer mill remains basically the same: Material is fed into a grinding chamber. Contact with moving hammers, and interior mill components reduce the material's size. Material remains in the hammer mill's grinding chamber until it is able to pass through a screen or grate with certain size openings.

However, hammer mills tend to have wide particle distribution rates, which means your feed may vary in size and shape. They also tend to consume more power than roller mills, which can lead to performance issues, excess heat, friction, and even spontaneous explosions. You may need to invest in explosion protection when operating at high volumes.
