There are many types of spray dryers used in the drying process. The most widely used machine is the centrifugal spray dryer. Its specific work is mainly to dry large materials, and to use small spray dryers for secondary drying. When using a spray dryer, a centrifugal spray dryer and a closed-loop centrifugal spray dryer are usually used, and the tower body of the former and the liner of the latter are worn to a large degree.
In the process of using the centrifugal spray dryer, it takes a long time to unload and load the tower body, so the material strength used in the design of the tower body is relatively high. Since the machine needs to continuously enter high-hardness materials during use, it will greatly increase the wear of the tower body, resulting in breakage of the tower body. When using a closed-circuit centrifugal spray dryer, the impact force of the liner is very large, so it is necessary to use materials with high wear resistance and strength during the design process.
When the spray dryer is in use, its wear speed should be reduced, and abnormal loss should be reduced and eliminated. It is necessary to use the equipment reasonably, do a good job in maintenance, and timely overhaul.
