Screw Press – AKUPRESS AS

AKUPRESS AS is used for the separation of organic and non-organic fraction before the digestion processes. Irrespective of whether organic substances are to be separated from packaging material, from municipal solid waste or from municipal bio-waste, AKUPRESS AS can handle all kind of input and separate the organics into the press juice. In general, the pressure of the screw press is build-up by a conical screw with adapted base heights and special spiral design. Here, the counter pressure is pneumatically adjustable. Also the drive of the screw press is based on a shaft-mounted gearbox on inlet side and the speed is adjustable through frequency converter.
