旋 流器以结构简单,分选效率高等优点,日益广泛应用于选煤作业中。我公司生产的水力旋流器和介质旋流器市场前景非常好 ,但实际使用过程中 ,存在以下问题 :(1)内衬型旋流器内衬易脱落,造成分选不稳定 ;(2)由于旋流器需要在较高的入料压力下工作,因此根部磨损较严重。磨损到一定 Cyclone with simple structure, high efficiency of sorting, increasingly widely used in coal preparation operations. The hydrocyclone and medium cyclone produced by our company have a very good market prospect. However, the actual use of the hydrocyclone and the medium cyclone has the following problems: (1) the inner liner of the inner cyclone is easy to fall off, resulting in unstable sorting; (2) ) As the cyclone needs to work at a higher feed pressure, the roots wear more severely. Wear to a certain
