Akupress A

The Kufferath Akupress A is a screw press for the dewatering of pulp reject / rejects from the recycling. It was produced in various sizes.

Operation principals:
The rejects are fed to the screw via filler chute of the screw press and propelled by the screw towards the press exit. The exit opening is kept closed by a conical ring which opens only when the internal pressure exceeds the pressing pressure set by means of a pneumatic ballowcylinder.
The internal pressure is builtup by the screws action on the rejects to be dewatered. This pressure drives the free water of the rejects through perforations of the basket enclosing the screw. Solids are retained and expelled by the screw through the press exit aperture.

Characteristics
– A wide filler chute on the crew press gives an input free from blockages.

– Generous depth of the conveying spiral and its large pitch allow the input of large solid lumps.

– Both screw and basket are cylindrical and hence nonclogging. The pressing pressure is created solely by a conical throttling ring.

– The press opening is positively closed by the cone and this allows an input of very low consistency rejects.

– The cone is positioned by a pneumatic cylinder. 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 whole press splits horizontally and this ensures simple maintenance.

– The perforated basket consists of two half-shells laid or welded into a supporting structure which takes up the applied stresses.

– The preforated basket is fully enclosed so that the presswater can be drained without splashing.

– Important components like motor, gears, bearings 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 subjects to abrasion are clad in highly wear resistant material. Repeated renewal of this wear layer is easily possible.

Double disc refiner Escher Wyss DSR

Escher Wyss Double disc refiner DSR

The Refiner DSR was produced by former exisiting company Escher Wyss which was taken over by Voith . It was available in three sizes DSR 1 / DSR 2 /DSR 3 and also in 2 different versions type CP and type HEP.

It is suitable for any pumpable suspension up to a consistency of approx. 6 % . Depending on the kind of fibre stock and the required stock and sheet characteristics, the refiner DSR is suitable for either fibrillating, cutting or brushing of fibres. The refiner can be adapted to a variety of tasks by various refiner fillings and the possibility of adjusting the specific edge load.

Working Principle
The fibre stock is passed through the inlet to the refining areas in either single or double flow. A satisfactory exchange of stock between rotor and stator is effected due to a suitable design of the flow cross section of the refiner filling, refining surface and edge length. The necessary buffer of stock is thus built up between the refining surfaces ensuring exceptionally uniform fibre treatment. The space between rotor and stator controls the refining results and can be precision adjusted by
means of the mechanical adjusting device. The power consumption varies with the space between the refining discs as does the specific edge load. Consequently the power consumption can be used as measure for the actual beating effect of the refiner. By the new way of stock flow in the machine, the stock pressure acts on the adjustable stator from both sides. In this way, the load is largely removed from the mechanical adjusting device and it only has to transmit axial forces for adjustment of the beating output.

Reel guillotine made by Boa

BOA Reel Splitters / reel guillotine

Reel splitters / reel guillotine are designed to cut defective or surplus paper reels to separate the residual paper from the cores. The cut paper will be further processed in e.g. a pulper or baler. BOA’s reel splitters are also applied to cut other than just paper reels, such as aluminium reels or wrapped bales.

A few characteristics of the Boa reel splitters:

No special foundation arrangements needed.
Smart and efficient design, resulting in reduced cutting time.
Uncomplicated operation and control.

Secure control and safe cutting

BOA’s reel splitters are safe and secure to operate that have, among other things, a safe two-hand push button control, forcing the operator to use both hands. Our reel splitters also have an emergency stop that will quickly move the knife upwards.

Depending on the application and where the machine will be placed, various options are available, such as an additional safety fence with a „light curtain“. When crossing the light curtain, the machine automatically shuts down.

Functionality and details

Compared to the hydraulic cutting machine, the mechanical reel guillotine is a more compact machine. The HRSM has a hydraulic drive and the RSM a spindle drive.

We have various types of HRSM reel splitters with different maximum cutting heights and widths. Our largest machine is able to cut reels with a maximum diameter of 2100 mm and a width of 3600 mm.

Our hydraulic cutting machine can be supplied with a conveyor system, if desired or necessary depending on the application. The conveyor belt is able to run in both directions. While running the belt forwards and backwards, the material can be easily cut in smaller pieces.

Washer Vario Split for ash removal

Washer Vario split

The Washer Vario Split is a machine for
washing fibre stock suspensions in the low density
range, i.e. for removing finest particles such as
e.g. ash and inactive fines as well as printing

ink particles detached from the fibre up to a grain
size of 30 – 40 pm. The long and short fibre content
is thereby increased in comparison to the composition
of the stock fed in. At the same time, thickening of
the fibre stock suspension takes place. At inlet
stock consistencies of 0.4 – 1.3 %, outlet stock con—
sistencies up to lo % are reached, depending on type
of stock and operating conditions.

Principle

The low density suspension supplied is distributed
by two distribution pipes uniformly onto the fish—
tail dies of the headboxes and sprayed into the
wedges between the turning wire and the central
rolls. Due to the one-sided dewatering between cen—
tral rolls and wire, a fibre web is formed which
runs along with the central roll and which is
picked—up by a doctor. The filtrate is collected

in a collecting tray and discharged.

Design of the machine

The frame is made up of MSH—hollow sections and
connected with cross beams. The construction ele—
ments are carried by foundation rails. The head—
boxes are screwed onto the frame.

The central rolls and all other lead rolls are pro—
vided with a rubber cover and supported on the frame.
The individual rolls are cleaned by means of doctors.
Two sticky doctors can be provided for cleaning the
central rolls.

The wire is tensioned via pneumatic cylinders. The
wire tension, which can be set according to the dia—
gram, must not exceed 7 N/mm. During wire change,
the roll automatically moves to run-in position when
the air pressure is removed.

For wire regulation, a guide roll is controlled by a
pneumatically working controller, for which special
instructions are enclosed.

When changing the rolls in the machine, they must be
placed on a roll board and removed from the machine.

For dismounting the lower central roll, an I—profile has
to be mounted in front of the roll, via which the roll
can be removed from the machine. The support under the
roll is removed simultaneously.

Algas Filter in various sizes

The Algas Filter / Microfilter is highly flexible and can be used for a wide variety of applications

Raw/River/Bore hole water
Fitted with a fine cloth, Microfilters are used for both river water and re-circulated in water cooling towers etc.

Stock preparation
Treating the filtrate from screw presses with the possibilities of recovering for re-use the clear water and saving the fibre, if appropriate. In some cases the water is passed forward to the bio-plant if it is not re-used. The Microfilter can also be used in this application to act as a fractionator, separating fines and ash from good fibre.

Treating dip sludge
A comparatively new application where instead of passing DIP Sludge to the primary effluent flow where it will add considerably to the contamination, the sludge is treated separately by a Microfilter, it passing directly to the effluent plant sludge presses and the clear filtrate being re-used back in the DIP plant.

Fibre and water recovery
Treating excess white water, saving fibre and providing a clarity of clear filtrate to safely replace fresh water on wire showers and other re-use areas. In this application it offers a more reliable solution than for example DAF Flotation units or Disc Filter solutions as it neither depends on vacuum/drop legs or generally the use of polymer and the resulting filtrate from Microfilters can said to be consistently reliable and “fibre free”.

Polishing after existing savealls
The “clear” water from most types of saveall generally varies in clarity and invariably contains fibre. This is the reason why our concept is installed to treat the “Clear” water from other savealls, such as Disc filters and DAF Flotation units, to provide a large amount of Super Clear quality water for safe re-use.

Polishing vacuum pump water
Felt hairs, cellulose debris etc. to re-use the water.

Primary effluent treatment
Initially considered impossible by most consultants, our Microfilters are used in the primary treatment position instead of or in conjunction with existing Sedimentation basins. It offers a very compact (5% of the holding capacity of sedimentation for the same capacity), fast installation (generally 1 week) which is very flexible in operation and because of the very short dwell time in the unit, minutes instead of hours. Consequently the sludge is not degraded making following thickening easier and provides the possibility for the fibre to be re-used in some production qualities, fluting, etc. Providing a good clarity to any following bio system reduces the amounts of bio sludge and subsequently chemical for thickening and disposal costs.

Polishing after bio sedimentation
To ensure the quality of resulting water can be discharged within statutory limits or re-used back in the process, depending on the type of production. The ALGAS Microfilters in all these application areas are essentially the same and so can, if required, be exchanged for any other application. This means that Microfilters DO cover more application areas than any other single type of concept. There are more special applications such as for Black, Red & Green Liquor and part of a plant to recover coating clay as well as in wet non-woven production units.
