The rotor is the heart of the sand making machine price. It is the most important working part of the sand making machine and the most vulnerable part. Whether it is a cobblestone sand making machine or a river gravel sand making machine, the rotor is very important. Therefore, the rotor is the most strict part of the sand machine acceptance. Our company has developed a sturdy heavy-duty rotor made of a new high-strength wear-resistant alloy to obtain a higher moment of inertia, and the latest design technology to optimize the crushing cavity of the sand making machine. The following is a brief explanation of the precautions for the installation of the rotor of the sand making machine and the damage factors of the rotor of the sand making machine.

Analysis of damage factors of sand making machine rotor

The sand making machine is powered by the motor after the power is turned on. The power is transmitted to the rotor through the bearing and the gear. The rotor rotates the crushed aggregate at a speed of 186 rpm. Among them, there are two factors that affect the wear of the rotor.

1. The cooperation relationship between the rotor and the bearing. The rotor bearing of the sand making machine is mainly subjected to the impact load during operation. The magnitude of the load on the rolling element is different. The rolling element under the combined action of the impact load is subjected to a large force, and the inner and outer ring raceways are also in the Here, the force is greater when it comes into contact with the rolling elements.

2. The bearing condition of the rotor bearing The impact load of the VSI sand making machine on the bearing 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 on the bearing. Load, therefore, adding a rubber plate of appropriate thickness between the bearing of the sand making machine and the support frame can improve the support flexibility of the bearing seat and improve the bearing condition of the bearing to achieve the purpose of prolonging the service life of the rotor.
