Environmental protection Long Service Life Coal Chemical Industry centrifuge
A centrifuge uses the centrifugal force exerted on the contents of a rapidly rotating container to separate fluids of different densities or to remove liquids from solids. They are widely used for mechanical solid-liquid separation of components in the chemical industries. Whether you are looking for a centrifuge to process salts, fertilizers, plastics, soda or cellulose, our experts can help you choose the right centrifuge for your application.
Centrifugal principle
When a suspension containing fine particles is standing still, the gravity field causes the suspended particles to sink gradually.The heavier the particle, the faster it sinks, whereas particles that are less dense than liquid rise.The speed of the particle moving in the gravitational field is related to the size, shape and density of the particle, as well as the strength of the gravitational field and the viscosity of the liquid.Particles the size of red blood cells, a few microns in diameter, can be observed settling under normal gravity.
In addition, there is diffusion phenomenon when the material settles in the medium.Proliferation is unconditional and absolute.Diffusion is inversely proportional to the mass of the material, and the smaller the particle, the more serious the diffusion.The settlement is relative, conditional, to be subjected to external forces to move.Settlement is proportional to the weight of the object, and the larger the particle is, the faster it settles.For particles smaller than a few microns, such as viruses or proteins, which form colloidal or semi-colloidal states in solution, it is impossible to observe the sedimentation process using gravity alone.The smaller the particle is, the slower it settles, and the more serious the diffusion is.Therefore, it is necessary to use a centrifuge to generate strong centrifugal force to force these particles to overcome the diffusion and sedimentation motion.
Centrifugation is to use the powerful centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the settling speed of the particles in the liquid and separate the substances with different settling coefficients and buoyancy densities in the samples
