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.
