SOLID PARTICLE CLASSIFIER AND SOLID PARTICLE CLASSIFICATION METHOD UTILIZING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a solid particle classifier with a simple structure capable of effectively classifying the huge amount of solid particles and a solid particle classification method utilizing the same. SOLUTION: The solid particle classifier is used for classifying the solid particles in a suspension using a settling tank, and comprises a suspension supply means for continuously supplying the suspension to the settling tank, a pair of electrodes immersed in the tank and space apart from each other to constitute a suspension passage by a space formed by the spaced-apart electrodes, a direct current power source for applying a voltage to the electrodes and a supernatant portion recovery means for continuously recovering the supernatant portion of the suspension passing through the passage. The solid particle classification method employs the classifier to control the pH concentration of the suspension and performs the classification by regulating direct voltage in response to the zeta potential of the solid particle.
