Since the work of the jaw crusher is periodic, the load of the motor will inevitably change periodically, resulting in an extremely unbalanced load. Therefore, large crushers are generally provided with a flywheel at each end of the eccentric shaft (one of the flywheels is also used as a pulley), while the flywheel of small and medium-sized crushers can be made one. According to the principle of
