Decanter centrifuge  is a new kind of horizontal spiral centrifuge discharge, its working principle is to use solid - liquid specific gravity difference, and relying on centrifugal force field to make it thousands of times to broaden the solid phase was settling under the influence of centrifugal force, and then end solid-liquid parting, and the role of the body especially the discharge arrangements parting. Entire feed and parting process are successive, close, automatically ends. Centrifugal sedimentation method parting parting suspension components centrifugal machine

Working principle of decanter centrifuge.

Participate in the drum suspension liquid layer constituting the ring in the centripetal force, during which the solid particles settle to the drum wall to form sediment. Clear liquid overflow port or through the drum pipette discharged, said parting liquid. When parting ended with manual or mechanical methods discharged sediment. Solid particles in the drum wall settlement process, but also with the axial movement of the liquid stream, the feed is too large, the activity with the liquid to overflow port, but did not settle into fine particles in the drum wall with the parting liquid discharge drum, so that the parting was cloudy. Solid-liquid phase density difference is small, small solid particles or liquid viscosity of the suspension should be selected hard parting parting factor high sedimentation centrifuge drum extending the suspension stay in the moment (for example, reducing the amount of feed or use long drum, etc.), can ensure the parting was clarified.
  

Two types of decanter centrifuge .

 Horizontal spiral centrifuge discharge settlement activity by the method can be divided into two kinds and countercurrent flow and, by parting the number of phases can be divided into two-phase and three-phase type parting parting type, according to the structure can be divided into ordinary distinction type, explosion-proof and airtight type three. Is a very broad use of centrifuges, mainly used to obtain relatively dry cake (solid phase deliquoring) or more clear parting liquid (liquid clarification). It can be used to leave a suspension of solid particles containing ≥0.005mm can also be used for classification of solid particles, the filter cloth is more suitable for regeneration of the parting material difficult, and the concentration of the particles of the suspension changes to a wider range of liquid, washing the filter cake also.

Widely usage of decanter centrifuge.

1. Industrial and domestic sewage separation and dehydration.
2. Chemical: gypsum, kaolin, graphite, fertilizer, resins, dyes, pigments, such as dehydration purification.
3. Food and feed categories: fish meal and fish dehydration, fruit juice and pulp fiber separation, soybeans, wheat protein dehydration, xylitol, corn fiber dehydration.
4. Plants and traditional Chinese medicine extraction: honeysuckle extract, tea polyphenol extract, wheat bran extract and so on.
