Its working principle is mainly based on the action of centrifugal force, which separates solid particles from liquids by cyclone. The cyclone desilter has the advantages of simple structure, convenient operation, and high efficiency. In water conservancy projects, it is usually necessary to extract the sediment from the riverbed, separate the sediment from the water, and then dry the sediment for use, while the treated and relatively clean water is discharged back to the water source.
