When the 300-ton sand making machine is crushing the material, the material is added to the inside of the equipment from the feed port and hit by the rotor, thereby completing the crushing purpose. If the rotor is damaged during use, the material cannot be crushed or the crushing is insufficient. The size of the discharge port of the equipment is set before starting, so the material cannot be discharged and causes blockage. At the same time, no qualified material is discharged, which reduces the production capacity and production efficiency of the equipment. It can be seen that the damage to the rotor is a great harm to the production of the sand making machine, so this phenomenon needs to be solved in time.

First, let us introduce the reasons why the rotor of the sand making machine is damaged during production. After summarizing, it is found that there are mainly two aspects, namely the matching relationship with the bearing and the stress condition. Let's introduce the reasons for these two aspects: 1. The matching relationship between the rotor and the bearing. When the rotor bearing of the sand making machine is working, the main source of force is the impact load. The magnitude of the load on the rolling element is different. The rolling element under the combined force of the impact load is under greater force, and the inner and outer ring raceways are also under greater force when they contact the rolling element here; 2. The stress condition of the rotor The rotor is the main part of the sand making machine that hits the material, but it will also be affected by force when it is used. The magnitude of this force depends on the impulse acting on the rotor and the support flexibility of the bearing seat. Increasing the support flexibility of the bearing seat can reduce the impact load on the bearing. For this situation, a rubber sheet of appropriate thickness can be added between the sand making machine bearing and the support frame to increase the support flexibility of the bearing seat and improve the stress condition of the bearing, thereby achieving the purpose of extending the service life of the rotor.
