Most sand dryers adopt a three-pass structure, which can provide a better closed space and drying environment for the material, and can greatly improve the drying rate and effect of the material. However, with the long-term continuous operation of the sand dryer, friction, and the moisture in the material, the equipment will also produce different corrosion, which will inevitably cause cracks in the cylinder of the sand dryer. What should I do if cracks appear in the sand dryer?
1. When cracks appear in the cylinder of the sand dryer, we can use small diameter welding rods and small current welding specifications for layered welding. Then carefully polish the welds to prevent deformation or breakdown of the cylinder.
2. If the cracks in the cylinder of the sand dryer are serious, the equipment can also be disassembled and welded as a whole. Or replace the drum. However, this method is not only complicated to operate. The project volume is large, and the cost is high, which has a greater impact on the drying production line. Therefore, it is not recommended when the cylinder is slightly worn or the cracks are light.
3. When we weld the cracks on the sand dryer cylinder, we must pay attention to carefully measure the surfacing with a ruler template to ensure that the external dimensions are qualified and avoid deviations.
4. In general, the cause of the cracks in the sand dryer cylinder is mostly caused by improper operation. This requires us to strictly follow the operating instructions during the use of the equipment to prevent equipment failures due to operating errors, which not only delays the entire drying operation, but also increases the maintenance cost investment for users.
Of course, in the actual application process, in addition to the cracks in the cylinder, the sand dryer will also produce other abnormalities. Zhengzhou Hengxing Heavy Industry reminds everyone to do a good job of regular maintenance of the equipment. Once a problem occurs, keep a record and formulate reasonable emergency measures to timely discover and eliminate safety hazards to ensure the safety and durability of the equipment.
