The granite hammer crusher is mainly composed of rotor assembly, muffler, shell, counterattack frame and driving part. The hammer head of the crusher mainly hits the ore in the upper cavity.

The impact of the ore on the counter-attack frame and the collision between the ore cause the ore to be broken. After the raw ore is fed into the feed inlet of the crusher through heavy-duty feeding equipment (such as an adjustable-speed plate feeder), it falls into the crushing cavity between the high-speed rotating rotor driven by a narrow V-belt and the counterattack frame.

The hammer was initially broken. After the initial crushing, the material is further crushed again between the rotor and the counter-attack frame during the downward movement, and then the lower crushing cavity formed by the muzzle and the rotor is crushed until the particle size is smaller than the size of the slit and is discharged from the lower part of the cavity.
