Impact crusher as the main equipment of the production line of sand making machine, its life is also the concern of many investors.
First, the model of the rotor bearing. As the impact crusher long-term work in harsh conditions, it will increase the wear of the rotor bearings. So correctly select the rotor bearing model.
Second, the force situation of the rotor bearing. Impact crusher impact on the bearing load, mainly depends on bearing support flexibility and the impulse acting on the rotor. Increasing the support of the bearing seat will reduce the impact load acting on the bearing. Improve the bearing force of the situation, so as to achieve the purpose of extending the service life.
Third, the balance of the rotor accuracy. The mass of the impact crusher is high, the speed is high, this centrifugal force causes the machine to produce forced vibrations, resulting in damage to the bearings and other parts, so the rotor of the crusher must be subjected to a balancing test.
