Abstract:
1. Device for measuring the apparent density distribution of a set of particles composed of several subsets of particles with different apparent densities and able to implement a flotation process to measure this distribution, comprising: a double-walled container having an inside and an outside wall defining an inner and outer chamber; a stirrer placed in the inner chamber; and a system for measuring a density of the liquids, wherein the inside wall of the container includes at least a first part in a shape of an inverted cone with a second axis whose height is 1.5 to 3 times a maximum diameter of the inverted cone, and the first part has extraction means for extracting liquid communicating with the first part at a vertex of the inverted cone, the extraction means having a tube communicating with the first part at the tip of the inverted cone of which a first axis makes an angle of between π/2 and 3π/2 radians with the second axis.
