A method for designing one part of an electrostatic separating device of a mixture of different material granules, the method including providing a sorting performance value to be met by the device when at least one predefined mixture is introduced into the device to be sorted, optimizing a value of at least one parameter of the set of parameters relating to the device part by using an optimization technique, the optimization technique including the use of a sorting performance model of the device, and the optimization technique occurring under the constraint that the sorting performed by the device has the given sorting performance value.

Method for designing an electrostatic separating device of a mixture of different material granules and associated devices

A device for triboelectric charging of a mixture of granules of different materials, the device having a charging chamber with walls delimiting an inner space. The walls define a granule inlet and a granule outlet, the granule inlet and the granule outlet being separated from one another relative to an elevation direction. A blowing device is arranged suitable for generating, in the inner space, an air flow suitable for allowing the granules in the chamber to form a fluidized bed, and a plurality of grids are positioned in the chamber, the grids being suitable for blocking the passage of the granules, the grids forming a set of baffles in the inner space between the granule inlet and the granule outlet.
