BT-2002 laser particle size distribution analyzer is a national engineering and technical centers and CWS Baxter Instrument Co., Ltd., Dandong City, the joint development of specific areas dedicated to coal-water slurry particle size distribution of the laser instrument. It is the use of coal-water slurry of coal particles can produce laser diffraction and scattering to measure the particle size distribution, high speed, easy operation, good reproducibility, etc., are coal-water slurry production and application of the ideal size enterprises measuring instruments. The system includes the optical measurement and signal conversion device (host), including laser, spatial filter, collimating and beam expanding optics, Fourier lenses, prisms, optical receivers and multiple circuit system; sample preparation system, there are scattered , mixer, circulating pump, the sample cell, sample transfer lines, etc.; computer systems, mainly computers, printers, test the software. Through the optical measuring device and sample preparation system to obtain the light scattering particle size signals, these signals transmitted to the computer for processing to obtain the results of particle size distribution of coal-water slurry. In addition, the instrument can be used to test other areas of coarse particle size powders.
