Low speed large capacity centrifuge on equipment selection principle

On low speed large capacity centrifuge the other information please visit http://www.shlxj.com.cn/ for more details.
Low speed large capacity centrifuge on liquid / solid, liquid / liquid heterogeneous mixture of separation mainly involves the solid particle materials and liquid materials. Low speed large capacity centrifuge to understand mechanical separation process is the main physical processes, separation of mechanical separation function quality, have great relations with physical function separation material. Such as the use of sedimentation principle of parting of the gravity sedimentation or sedimentation type centrifuge with solid phase particle size distribution, particle shape, density of solid and liquid phase density, viscosity and surface tension are closely related. Low speed large capacity centrifuge for separation of various sedimentation type mechanical habit scale according to the material's properties to distinguish. Using filtering way to various filter mechanical separation is closely related with the solid material particle size distribution, material compressibility, particle shape and particle swarm specific surface area and between the liquid viscosity, surface tension and solid-liquid affinity degree. Low speed large capacity centrifuge suggested determination of solid suspended particles in the formation of a filter cake filtration speed rate and suspension of settlement of liquid phase and the property to a comprehensive reflection of material, used to determine the degree of difficulty of material. According to the sedimentation and filtration material characteristic experiment reflects, can be used as mechanical type according to the selected separation. Low speed large capacity centrifuge to be some special properties of separation material and on the separation obtained some special commodity demand, low speed large capacity centrifuge advice must try to think in the selection, for example:
(1) liquid phase is volatile or easy to cause the blasting and flammable materials, using vacuum filtration cannot demand and hermetic explosion-proof.
(2) strong corrosive materials, on the separation machinery material selection with special needs.
(3) the solid particle hardness is larger, it needs the selected separation machinery data good wear resistance.
(4) were parting material, whether it is a solid or liquid phase, if to precious materials, the demand of high recovery rate.
(5) solid phase material for crystallization of goods, crystallization parting the damaged degree of low demand. Methods the mechanical structure of separation and discharge way, have special needs.
