The new Aeroselector combines wind sifting, ballistic separation and screening in one machine. Its throughput but especially its compact design and its efficiency are very convincing.
In professional composting plants this machine already proved itself successfully in separating foils, stones and structural material from the screen overflow. Also other moist and try material mixtures consisting of differently sized fractions can be split up effectively with this solution.
First a screen or a conveyor belt discharges the humid or dry compost screening residues on an acceleration belt, which takes care of the optimal speed and distribution of the material.
In the transfer area from the acceleration belt to the downstream conveyor belt, an air flow is fed in from below. This removes foils and light goods from the material flow. The detached foils move along the cover of the wind sifter unit to an edge at which other adhering material can be removed. A suction system then transports the foils e.g. into a separate standard container.
Heavy, small and spherical material falls off the acceleration belt and bounces off the front roller of the next conveyor belt. The conveyor belt now transports the remaining material to a star screen, where elongated, lumpy material (e.g. twigs) is separated from the oversized remaining pieces (e.g. branches).
