When the sand making machine crushes materials, the materials are put into the equipment from the feed port and hit by the rotor, thereby completing the purpose of crushing. During long-term use, the sand making machine is prone to various failures. If the rotor is damaged, the material will not be crushed or the crushing degree will be insufficient, and qualified materials will not be crushed, which reduces the production efficiency of the equipment. Therefore, when the rotor is seriously damaged during the production of sand making machine, the cause needs to be found and solved in time. 1. Cooperation between the rotor and the bearing

When the rotor bearing of the sand making machine is working, the main force source is the impact load. The load on the rolling element is different. The rolling element is affected by the combined force of the impact load. The force is greater, and the rolling element is also under greater force when it contacts the raceways of the inner and outer rings here; 2. The stress condition of the rotor

The rotor is the main component that hits the material during the production of the sand making machine , but it will also be affected by force when used. The magnitude of this effect depends on the impulses acting on the rotor and the support flexibility of the bearing housing. Improving the support flexibility of the bearing seat can reduce the impact load acting on the bearing. In response to this situation, a rubber plate of appropriate thickness can be installed between the bearing and the support frame of the sand making machine, which can improve the support flexibility of the bearing seat and the stress condition of the bearing, thereby extending the service life of the rotor.

The above introduces to you the factors that cause damage to the rotor of the impact sand making machine. If the above answer is useful to you, please encourage me to like me so that I can help more people. Thank you!
