Provided is a micro-element recycling method and system. The method includes: collecting at least one micro-element failing in transfer; applying a first acting force to the micro-element in a first direction, and applying a second acting force to the micro-element in a second direction; moving the micro-element from an initial position to a target position by means of the combined action of the first acting force and the second acting force; and recycling the micro-element located at the target position.

The present invention relates to a method for separating and collecting single aggregates from fumed silica, and a method for classifying a shape of the collected single aggregates, and more specifically, includes preparing a slurry in which fumed silica is dispersed in water; aerosolizing the slurry; and collecting single aggregates of the finned silica in the aerosol using the electric field.

A method and system for air classification of a milled feed stock includes generating a feed stream by combining the milled feed stock with at least one gasflow element, wherein the milled feed stock includes a plurality of particle sizes. The method and system includes directing the feed stream across a curvilinear surface, such that the milled feed stock in the feed stream separates into a plurality of classification streams, each of the plurality of classification streams based on the particle sizes of the milled feed stock. Therein, the method and system separates the plurality of classification streams and collects each of the plurality of classification streams, thereby classifying the milled feed stock contained therein based on the particle sizes for each of the plurality of classification streams.

An electrostatic separation device (is for a mixture of granules of different materials. The device includes a separation chamber having an inlet and delimiting an inner volume and a collection device for granules placed in the inner volume, opposite the inlet. At least two pairs of electrodes are successively placed in the elevation direction in the inner volume, between the inlet and the collection device. Each pair includes an anode and a cathode, placed on either side of a central axis extending in the elevation direction. At least one generating system is suitable for applying a difference in electric potential between the anode and the cathode of each pair.
