Which Effect Is Better Between Spiral Classifier & Hydrocyclone
Hydrocyclone is a kind of high-efficiency classification and desliming equipment, which is used to separate and remove heavy and coarse-grained mud sand and other substances in sewage. Because of its simple structure, easy manufacture and large processing capacity, it has been widely used at home and abroad, and sometimes it is also used for mud dewatering.
