How does a hammer crusher work? Hammer crusher mainly relies on the impact force to complete the crushing. When the hammer crusher works, the motor drives the rotor in high-speed rotation. The materials are sent into the crusher chamber evenly and after a high-speed impact of hammer, the material is crushed into a smaller size.

Breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory. High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers.
