Settling particle size analyzer, also known as settlement scale, is generally composed of high-precision electronic balance, settlement system, and data processing software. It is an instrument that physically measures the size and distribution of solid particles. The sedimentation particle sizer is manufactured according to the Stokes' theorem. The basic content of the Stokes principle is: during the sedimentation process of dust particles, particle grading occurs, so the viscosity of the stationary sedimentation liquid acts as a frictional resistance to sedimentation particles and is calculated according to the formula:
r=9η/[2g(γk−γt)]·(H/t) where:
r=particle radius cm
η = viscosity of sedimentation liquid, i.e. g/cm·sec γk = particle specific gravity g/cm γt = sedimentation liquid weight g/cm H = sedimentation height (distance of the liquid to the bottom of the pan) centimeter t = sedimentation time second g = Gravity acceleration 980 cm/s When the time t required for the particles to settle to a certain height H is measured, the settling velocity V and the particle radius r can be calculated.
The sedimentation type particle size analyzer is an intelligent particle measurement instrument manufactured based on the Stokes' Settlement principle and can measure particle size and distribution between 1 and 600 μm.
When the instrument is used, as long as the object to be measured (3 ~ 10g, or determined according to the nature of the sample and the amount of experience to determine the amount of sample) after drying in the settling solution in 500C.C, after stirring test. The computer automatically records the settling curve, and then calculates the particle size, average particle size, median diameter, specific surface area, and average error; particle distribution analysis; calculation results, chart printing, and the like.
The new settlement type particle size analyzer is a combination of traditional theory and modern technology. It uses computer technology, microelectronics technology, and even Internet technology. It has made great progress in instrument intelligence and automation. It also has many types, such as BT-1500, SA-CP4, and SG5100. The settlement type instrument has the following characteristics:
Operation, maintenance is simple and the price is low.
Long running time, some up to 12 hours or more.
Low operating costs, fewer samples, less media usage, and fewer wearing parts.
Wide range of testing, generally up to 0.1 ~ 200μ, repeatability and accuracy (real) is better.
The test time is short, and the single measurement time is usually about 10 minutes.
The requirement for the environment is not high and it can be operated at normal room temperature.
