Sand making machines (impact crushers) are core equipment for machine-made sand production, and their wear parts (impeller, impact plate, lining plate) are easily worn due to long-term contact with high-hardness materials. Reasonable replacement and maintenance of wear parts can extend the service life of the equipment and reduce production costs.
### Common Wear Parts and Replacement Standards
1. Impeller: The impeller is the core wear part of the sand making machine, which is responsible for throwing materials. When the wear amount of the impeller exceeds 10mm, or there are cracks and deformations, it should be replaced in time. The replacement cycle of the impeller is usually 3-6 months, depending on the material hardness and processing capacity.
2. Impact Plate: The impact plate is used to bear the impact of materials. When the wear amount of the impact plate exceeds 15mm, or the surface is severely uneven, it should be replaced. The impact plate can be turned over and used after one side is worn, which can extend the service life by 50%.
3. Lining Plate: The lining plate is used to protect the crushing cavity. When the lining plate is worn through or falls off, it should be replaced immediately to avoid damage to the equipment body. The replacement cycle of the lining plate is usually 2-4 months.
### Maintenance Tips
1. Regular Inspection: Check the wear condition of wear parts every day before starting the machine, and record the wear amount. Check the connection of wear parts to ensure that they are not loose.
2. Lubrication Maintenance: Add lubricating oil to the bearing and other rotating parts on time to reduce friction and wear. Replace the lubricating oil every 3 months to ensure the lubrication effect.
3. Material Control: Control the feeding size and avoid large hard impurities entering the crushing cavity, which can reduce the wear of wear parts.
4. Correct Installation: When replacing wear parts, ensure that the installation is correct, and adjust the gap between the impeller and the impact plate to the appropriate size, which can improve the crushing efficiency and reduce wear.
