When the rotor is rotating at high speed, the hammers strike the material inside the machine due to centrifugal and rotational forces, causing it to break.

There are two types of hammer crushers: single and double rotors, single and multiple rows of hammers according to the arrangement of the hammers on the turntable, and two types of reversible and irreversible rotor steering. There are also a number of simple hammer crushers, such as cross hammer crushers.

The hammer crusher mainly relies on the impact to crush items, when the items need to be crushed into the hammer mill, will suffer the impact of the high-speed rotary hammer head to achieve the crushing of items, crushed materials will be obtained from the hammer breakers hammer head kinetic energy, at the same time, the items will hit each other, after being broken many times, less than the screen bar items will be shot out of the gap, the hammer mill through the continuous The hammer crusher works in a continuous cycle, thus realising the crushing of items.
