The surface of our crusher rotor is protected by a tungsten-titanium alloy armor design, which reduces stress concentration on the hammer plate and end plate, enhances their strength, and effectively prevents hammer plate breakage and jamming in the crusher. This significantly extends the lifespan of the rotor, doubling the rotor's service life.
