Symmetrical deep crushing chamber is adopted to maximize the range of feed size, capacity and crushing ratio. 2. Three-dimensional software is adopted to optimize crusher parameters and reduce equipment self-weight, so capacity is increased by more than 30%. 3. Bearing seat is designed integrally, so manufacturing difficulty is greatly reduced, and bearing life is increased. 4. There is a thick replaceable plate on the top of moving jaw to prevent moving jaw from being impacted. Working princle: the motor transmits through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when mobile jaw moving. So the mobile jaw moves towards the fixed jaw.
