Found stable jet classifier, a uniform velocity distribution is to improve the classification of the key to effective

Studied fine diamond powder fluid classification technology, designed a jet classifier, and diamond powder dispersed in water were studied. Study found that the jet classifier stable, uniform velocity distribution is the key to improve the grading effect, the jet fully developed pipe flow velocity sections obtained relatively uniform  cubic boron nitride  field, the grading points are located in this section obtain better classification results. Entrainment flow jet formation can get a good secondary dispersion powders. Meanwhile, the fluid flow rate, feed rate, feed location, also have a  synthetic diamond on the classification results. To improve classification results, the paper diamond powder dispersed in water for a preliminary exploration.that the diamond powder dispersed in pure water is poor, however, by adding an electrolyte dispersing agent can improve dispersibility in water. Sodium silicate and sodium pyrophosphate diamond powder is a good dispersant, the dispersion liquid concentration 1g / L ~ 1.5g / L the optimum dispersion.
