Disc centrifuge is a type of vertical centrifuge. The drum is mounted on the upper end of the vertical shaft. It is driven by a motor through a transmission device and rotates at high speed. There is a small gap between the discs and the discs, and there is a set of discs stacked on top of each other in the drum. The machine has high working efficiency and can provide two kinds of operation forms: first, liquid, solid separation (namely the bottom concentration of suspension separation), known as clarification operation; Second, liquid-liquid separation (or liquid-liquid solid) separation (i.e. emulsion separation), known as separation operation. Application range: liquid purification, solid concentration and dehydration, wet classification, liquid mixture separation, component extraction. Industry application: food (protein, dairy, beer, starch, fruit juice, beverage), environmental protection, animal and vegetable oil (lanolin, seed oil, fish oil, biodiesel, etc.), biology, biochemical, mineral oil, chemical industry, medicine and other industries.
