  • Device and method for separating feedstock into at least one light material fraction and a heavy material fraction
    Patent number: 9138780
    Abstract: A fractionating device comprises at least one inlet for feedstock, at least one light material outlet for a light material fraction and at least one heavy material outlet for a heavy material fraction. A flow generator for generating gas flow in the fractionating device for separating the light and heavy fractions. A curved centrifugal separating device separates the light material fraction from the gas flow. A conveyor downstream of the inlet carries the feedstock into the centrifugal separating device. At least 50% of the gas can be conducted in the fractionating device as a circulatory flow which is conducted around the conveying device.
