How To Choose A Centrifuge？

It is widely used in the medical field, and blood separation, virus research, DNA research, and drug purification are widely used in centrifuges. It has the characteristics of good adaptability, high degree of automation, stable operation, strong processability, good corrosion resistance, good operating environment, complete and reliable safety protection device and beautiful appearance. The centrifuge used in the refining process such as drug purification is a general low-speed centrifuge with a rotation speed of less than 4,000 rpm and a large amount of processing. In order to meet the GMP specifications and requirements for pharmaceutical production, it is generally made of flat stainless steel.

The centrifuge should be selected according to the size and concentration of solid particles in the suspension (or emulsion), the difference in density between solid and liquid (or two liquids), the viscosity of the liquid, the characteristics of the filter residue (or sediment), and the requirements for separation. A comprehensive analysis was carried out to meet the requirements for the moisture content of the filter residue (sludge) and the clarity of the filtrate (separation liquid), and which type of centrifugal separator was initially selected. Then according to the amount of processing and the automation requirements for the operation, determine the type and specifications of the centrifuge, and finally verify by the actual test.

Generally, for suspensions containing particles larger than 0.01 mm in size, a filter centrifuge can be used; for fine or compressible deformation of the suspension, a sedimentation centrifuge should be used; for the suspension, the solid content is low, the particles are small and When the liquid clarity is high, a separator should be used.
