Sand making machine is suitable for crushing ore materials. It is less affected by the moisture content of the material, and the moisture content can reach about 8%. Manufactured by sand making machine equipment manufacturers, it consists of seven parts: feeder, distributor, vortex crushing chamber, impeller, main shaft assembly, base transmission device and motor. When working, when does the sand making machine rotor need to be leveled? How to level it? What issues do sand making machines need to pay attention to?
When the material falls into the feed hopper, it enters the high-speed rotating rotor through the central feed hole and is fully accelerated and thrown out through the launch port. It * collides with a part of the material that falls freely after rebounding, and then impacts the vortex material lining (or counterattack block) in the surrounding vortex cavity. It is * rebounded to the * of the crushing chamber, and then deflected and moves downward, colliding with the material emitted from the impeller flow channel to form a continuous material curtain, and then discharged through the lower discharge port.
During the entire crushing process, the materials impact and crush each other, and do not come into direct contact with metal components. Instead, they impact and rub against the material lining and crush them, which reduces pollution and prolongs the mechanical wear time. In addition, the ingenious self-circulation of airflow inside the vortex cavity eliminates dust pollution.
The rotor is the core component of the sand making machine. Before leaving the factory, the manufacturer will use an online dynamic balancer to ensure the balance of the rotor of the sand making machine by adding counterweights to the rotor. After long-term use on site, the rotor is unbalanced due to wear and other reasons. The unbalanced rotor will cause excessive machine vibration, low sand making efficiency, and reduced service life of the main shaft assembly. Therefore, it is very important to ensure the balance of the rotor. Today, I will share with you why the rotor needs to be balanced and the steps for correction. What problems should be paid attention to in the sand making machine?
When to perform balance correction
1. After the rotor repair operation, such as hardening treatment;
2. If the machine vibrates *ly but the wear plate is in good condition, it is recommended to check the balance of the rotor.
Steps of rotor correction
After understanding the reasons and timing of correction, we also need to understand the specific operation steps. Only by understanding the steps can the correction process be completed. Generally speaking, the steps are mainly divided into four:
1) Because the rotor of the impeller will also wear when the sand making machine is running, so when correcting the balance after replacing the wear parts, it is necessary to * clean the sand and gravel, old wear parts, etc. on the rotor and its accessories, and confirm that they can continue to be used, otherwise there is no need to correct the balance. The rotor needs to be replaced before correction;
2) Reinstall the wear-resistant parts and install the rotor on the balancing tooling;
3) Determine the weight and position of the unbalanced counterweight;
4) Review the balance of the balanced rotor to ensure the effect of the correction;
In production, the *, inner side and lower edge of the rotor are all places that are easy to wear. Check whether the machine is running normally every day, and regularly check whether the transmission triangle belt is tightened. If it is too loose or too tight, it should be adjusted appropriately to ensure that the triangle belt should be grouped and matched so that the length of each group is as consistent as possible.
