Laser Diffraction Particle Size Analyzer (BT-2002)

It is especially applicable to test particle size in the field of the coal water slurry (CWS). Particle size distribution is measured by using the light diffraction and scattering phenomenon caused by coal fines in the CWS.

Applications
Coal Water Slurry (CWS), coal powder.
Coarse powders: gunpowder, catalyst, core, sediment, chemical raw materials and its products, non-metallic minerals, etc.

Principle
Laser particle size analyzer measure the particle size on basis of the phenomena that laser will diffract on partilces.In case the light beam is blocked by particles,part of them will diffract ,angle θ will be formed between diffracted light and the main beam.Both diffraction theory and results from experiment show that angle θ is related to size of particle,the larger the particle is,the smaller the θ is;the smaller the particle is,the larger the angle is.Further research shows that strength of diffracted light represent number of the particles,thus particle size of the sample is obtained through measuring strength of the diffracted light at different angle.
