An installation intended to separate the components of a mixture containing fibers (2) and granules (3) is provided. The installation comprises a tribocharger (4) for conferring an electrostatic charge upon the components (2, 3), and at least one pair of electrodes (5, 6) for generating a separating electric field that conveys the charged components, according to their polarity, up to collectors (10, 11). The tribocharger (4) has a containment grating (14) arranged so as to retain the components in the tribocharger (4) until the components (2, 3) have reached a sufficient charge, then to allow the components, once charged, through into the gap (7), from which point the components (2, 3) reach their collector (10, 11) under the effect of the separating electric field.

The present invention relates to a dust removal apparatus and, more specifically, to a dust removal apparatus preventing a raw material from absorbing water when coming into contact with the outside air by separating the raw material from dust through an electrical reaction.

A method for recovering metallic materials from crystalline silicon photovoltaic modules. The method includes removing aluminium frames and junction boxes from the photovoltaic modules to provide photovoltaic sandwich structures. The method further includes shredding the photovoltaic sandwich structures to form photovoltaic sandwich structure particles and electrostatically separating the photovoltaic sandwich structure particles into a first fraction and a second fraction with an electrostatic separator. The method further includes feeding at least a portion of the second fraction to an electrostatic separator for one or more subsequent electrostatic separations into the first and second fractions, wherein the first fraction includes less than 5 percent by weight of total polymer particles and is substantially free of glass particles.

An installation is provided that is intended to separate two families of components of a mixture placed in a receptacle. The installation is provided with a screen and comprises a first electrode, a second electrode, and a generator that generates, between the first and second electrodes, an agitating alternating electrical field. The alternating electrical field is capable of alternately projecting all or some of the components of the mixture that is present in the receptacle towards or against the first electrode and then towards or against the second electrode in order to generate mechanical impacts on the components that contribute to breaking down the mixture within the receptacle and in order to facilitate the passage of components belonging to the second family through the screen. The screen ensures components belonging to the first family are retained in the receptacle.
