Heavy solid is deposited on the inner wall of the bowl，and forms the sludge. And it will be discharged by manual after the machine stops. The clear liquid flows out of outlet from the top of the bowl. It is mainly used for separating all kinds of suspension difficult to be separated, especially suitable for separation of solid-liquid suspension with light concentration, heavy viscosity, fine particles and very small differential gravity of the two phases. For example clarifying all kinds of medicine fluid,glucose chlorhexidine, malic acid, oral solution, radix soghorae tonkinensis, coal tar and graphite; extracting protein, saponin, pectin, sirup; blood separation, settling vaccine mycelia and all kinds of glucose; refining paint, resin, and latex solution.
