1. introduction

BT2002, for CWM particle test,is developed by National Project Technology Center of CWM and BETTERSIZE. It utilizes the property that the CWM particles can cause laser diffraction and laser dispersion.Fast speed, easy operation and good repeatability,it is ideal particle size test instrument for CWM producer and user. It includes optical testing and signal transforming device (main engine) comprising laser generator, spatial filter, laser beam collimation and laser beam expansion system, Fourier lens, prism, multi-element photoelectric receiver and electric circuit system, etc; sample preparation device comprising disperser, stirrer, circulation pump, sample pool, sample feeding pipeline, etc; computer device comprising computer, printer, test software, etc. It gets particle diameter signal through laser dispersion created by optical testing device and sample preparation system, then transmit these signals to computer for CWM result. Besides, it can also test the particles of fairly coarse powder.

3. 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.
