Laboratory centrifuge in centrifugal process common centrifugal filtration, centrifugal sedimentation and separation of three kinds of high heart. Laboratory centrifuge learned centrifugal filtration process used to more separation of solids, solid-liquid mixture for larger particles, separation process in general can be divided into three stages: the first stage, the solid particles by centripetal force accumulation to the drum wall constitute the residue layer, filtrate also borrow to heart of force through the drum mesh and filter out. The second stage, is pressing the residue layer under the action of the centripetal force, and will be contained in the filter hydraulic extrusion. The third stage, the residue layer void contained in the liquid under the function of centripetal force, continue to be discharged, so that the filter residue further boring. Suspension centrifugal sedimentation process can be used for containing solid particles separation small forest, laboratory centrifuge to know separation process in general can be divided into two stages: the first stage, the solid particles by centripetal force accumulation to the drum wall. The second stage, the settlement of granular layer in the drum wall, is pressed under the function of centripetal force. When the suspension solid content more, the settlement of particles deposition set, slag layer quickly thickening, therefore requests continuous slag. When the suspension solid content reported less, can be regarded as a single particle in the centripetal force under the action of free sedimentation, slag layer growth slow, can adopt the intermittent slag to the latter also known as centrifugal clearance process. Centrifugal separation process is composed of different rice respectively severe liquid emulsion, under the function of centripetal force of liquid by severe difference stratification, then leads. Centrifugal clarification and centrifugal separation, due to the solid phase volume in the process of separation reported less or both liquid, continuous operation so that the high effort easier to stop charging, discharging, but the separation factor to higher demand of very good separation, the centrifuge is also called parting machine.
