Operating principles AKUPRESS ! A The materials to be treated are fed to the screw via a filler chute and propelled by the screw towards the press outlet. Depending on the application, the screw speed can be unchangeable (constant) or changeable. The exit opening is kept closed by a conical ring which opens only when the internal pressure exceeds the pressing pressure (basically 2-5 bars). This pressing pressure is set by means of a pneumatic cylinder or pneumatic bellow. The internal pressure is built up by the screw action on the materials to be dewatered. filler chute screen basket The internal pressure drives the free liquids (and pasty stuff) of the treated materials through perforations of the basket enclosing the screw. Solids are retained and expelled by the screw through the press exit aperture. Depending on the application, it is possible to choose screens with different hole diameters or even screens with different sizes of slits. screw conical ring Bilaga 8
Characteristics AKUPRESS ! A " A wide filler chute ensures an input free from blockages " The generous spiral height and its large pitch allow the input of large solid lumps " Both screw and basket are cylindrical and hence non-clogging. The pressing pressure is created mainly by a conical throttling ring. New : For dewatering of rejects from pulp and woodpulp installations special screws with lower spiral height and conical pipe are used " The press opening is positively closed by the cone and this allows an input of very low consistency rejects. " The cone is positioned pneumatically. This makes it possible to set the pressing pressure reproducibly at any level required independent of the throughput quantity. On the other hand, it also allows automatic adjustment of the throttling aperture (i.e. the press opening) to the throughput. " The screw is supported by bearings at both ends. " The perforated basket consists of two half-shells laid or welded into a supporting structure which takes up the applied stresses. The whole press splits horizontally and this ensures simple maintenance. Alternative: The two parts of the basket can alternatively be mounted on steady half-shells which are only laid into a supporting structure " The perforated basket is fully enclosed so that the press water can be drained without splashing. " Important components like motor, gears, bearing and pneumatic cylinder are not specially made but are standard products of reputable manufacturers. This simplifies stocking of spares. " To prolong the life of the screw, all parts subject to abrasion are clad in highly wear resistant material. Repeated renewal of this layer is easily possible. " A standard consignment comprises, apart from the screw press itself, a pneumatic cabinet for control of the pneumatic cylinder and an electric cabinet providing the main operations as well as an electronic blockage fuse. " The screw presses can either be furnished in steel or stainless steel. The supports and baskets are normally made of stainless steel, the basic frames are finished in galvanised steel. Bilaga 8
