METHOD FOR DETERMINING THE EQUIVALENT Hydrodynamic granulometrics AND POSSIBLY RESULTING granular DIFFERENCE, AND THUS USED DEVICE.

摘要

A method of determining the equivalent hydrodynamic granulometry of a material by means of hydro-cyclone separation, according to which method a suspension of the material from a receptacle (1) to a hydrocyclone (2) having an upper conduit (12) and an underflow pipe (11) feeds, characterized in that one slelchts a single hydro-cyclone (2) is used warvan one the lower run to the receptacle (1) recycles, one at defined intervals takes a well-defined volume of sample from the upper course, it is the samples taken dries and it weighs them, and one on the basis of the masses of the samples in function of time and taking account of the Gx-curve of the hydro-cyclone, will calculate the granulometry.
