Abstract: An automatic centrifugal machine with lateral filtration used for realizing a highly effective separation of hardly separable fine sticky solid particles. It is equipped with a rotatable sediment drum having a radial filter plate, infrared fluid level monitor device, microcomputer programme control system as well as installations for hydraulic drive, automatic speed adjustment, automatic washing and discharge etc. That can realize a lateral filtration without filter cakes, thus attaining the object of a highly effective separation, complete discharge, undestroyed crystals, filter media easily regenerated and an operation of automation. It is especially suitable for the work of taking measures against poisoning, explosionproof and radiationproof.
