The demands on our sieve and separation technology are steadily increasing. This special finger sieve with counter-oscillating frame has been specially adapted to today's requirements. Acceleration, angle of attack and stroke of the sieve can thus be adapted to the circumstances.In this special case, demolition of construction mix is screened in preparation for a robot sorting. Finger spacing and drop height can be selected so that the right configuration is available for every material.The screening technology can also be equipped with a counter-oscillation frame (see photo) in order to avoid any vibrations in existing steel structures.
