The Decanter centrifuges made in China are different from the imported ones. The imported decanter centrifuge with the same function is about 6 to 10 times cost than the domestic one.
The reason is that the imported Decanter centrifuge is durable, and the control of temperature and speed is more accurate. The price difference between centrifuges of the same grade is not very big, mainly distinguished in performance and configuration. The difference of the equipment is that in terms of performance, centrifuges with freezing are much more expensive than ordinary ones. Some centrifuges also have heating functions. The more control programs, the higher the price of the centrifuge. The big difference is the configuration. Sometimes the price of accessories is higher than the price of the equipment. When purchasing, please note that in addition to the equipment, the selected rotor (number and type), plus the necessary centrifuge tubes, tube sleeves, special centrifuge bottles or blood bags, all of which add up to a complete centrifuge price. Centrifugation is to use the strong centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation speed of particles in the liquid, and separate the substances with different sedimentation coefficients and buoyancy density in the sample. Therefore, it is necessary to use a centrifuge to generate a strong centrifugal force in order to force these particles to overcome the diffusion and generate a settling motion.
A Decanter centrifuge is a machine that uses centrifugal force to separate components in liquid and solid particles or a mixture of liquid and liquid. The Decanter centrifuge is mainly used to separate the solid particles in the suspension from the liquid; or to separate two liquids with different densities in the emulsion that are incompatible with each other (such as separating cream from milk); it can also be used to exclude Liquid in wet solids, for example, dry clothes in a washing machine; special super-speed tubular separator can also separate gas mixtures of different densities; the use of solid particles with different densities or particle sizes to settle in liquids at different speeds, some of them settle The centrifuge can also classify solid particles according to density or particle size. Centrifuges are widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipping sectors.
In ancient China, people used one end of the rope to tie the pottery pot, held the other end of the rope, and flicked the pottery pot to generate centrifugal force to squeeze out the honey in the pottery pot. This was the early application of the principle of centrifugal separation.
