Most of the sand dryers are in the form of a three-stroke structure, which can provide a better-closed space and drying environment for materials, and can greatly improve the drying rate and effect of materials. However, with the continuous operation of the sand dryer for a long time, friction, moisture equipment in the material will also produce different corrosion, will inevitably lead to cracks in the sand dryer cylinder, cracks in the sand dryer. How to solve this problem?
1. When the sand dryer cylinder cracks in the body, we can use small-diameter electrode, small current welding specifications, lamination welding repair. The welding joint is then carefully polished to prevent deformation or breakdown of the cylinder.
2. If the sand dryer cylinder crack is more serious, you can remove the equipment after the whole welding repair or replace the drum. However, this method not only has complicated operation, a large amount of engineering, but also has a high cost, which has a great influence on the drying production line. Therefore, it is not recommended to use in the case of slight wear or light crack in the cylinder.
3. When we weld the cracks in the shell of the sand drying equipment, pay attention to the use of a ruler template to make a careful measurement of the surfacing, to ensure that the dimensions qualified, avoid deviation.
4. In general, the sand dryer cylinder crack production reasons are mostly caused by improper operation. This requires us to strictly follow the operating instructions in the process of using the equipment to prevent the occurrence of equipment failures caused by operational errors, this not only delayed the whole drying operation but also increased the cost of maintenance to users.
Of course, in the actual application of the process, in addition to the sand dryer cylinder cracks, there will be other anomalies. Zhengzhou Dingli reminds customers to do a good job in the regular maintenance of equipment. Once problems occur, we should make records, formulate reasonable emergency measures, find out and eliminate safety risks, and ensure the safety and durability of the equipment.
