Screen selection- inner drumScreen selection will depend greatlyon whether capacity or optimumseparation is required as the crophas to pass through the screen.Screens with smaller perforationswill improve separation of the largerimpurities – but at a reduced capa-city. Conversely, larger perforationsincrease throughput, but there is areduction in the amount of impuritiesremoved.

Screen selection– outer drumAs the crop is retained by the outerdrum screens, the dimensions ofthe perforations determine the finalsize of the cleaned grain. Selectinga screen with perforations that aretoo large will result in smaller, goodgrain being removed.

The illustration shows the separate disposal of impurities. A TRL 55 removes screenings, and aspirated impurities are conveyed away by the combi-cleaner’s fan. The DPC 40 is shown equipped with transport wheels and drawbar (optional extras).

Why choose theKongskildecombi-cleaner?Air cleaning following screencleaningThe impurities that are loosened - butnot separated - by the movement ofthe crop in the screens will be separated in the aspiration chamber.

Combined conveyingof impuritiesImpurities are separated in the screensection as well as during aspiration:A: All impurities may be conveyed by

the combi-cleaner fan.B: Impurities may be kept separate,

allowing those from the screens tobe discharged through gravity outlets and light impurities to beconveyed by the aspiration fan.

Easy screen raplacementBoth the inner and outer screenshave a quick-release system attached to the screens to allow easyreplacement without the use of tools.

Adjustable angle of inclinationThe combi-cleaner is provided with aspirit level to show the inclination.This makes it easy to adjust the ma-chine to the right angle of inclination(normally 4° to the rear).

Easy maintenanceThe combi-cleaner is easy to serviceReplacement and tensioning of beltsare quickly effected by means of thespecial tensioning equipment..

Enclosed systemThe machine can be provided with acomplete set of dust covers.

High degree of accuracyThe punched screens are made ofsheet steel om computer controlledmachinery to ensure a high degree ofaccuracy and uniformity. The screenslot sizes do not vary as in wire screens.

Rotary screensThe DPC 40 is equipped with rotaryscreens, eliminating the vibrationscaused by forward and backwardmovement.

Tractor drivenThe DPC 40 is also avaiable in ap.t.o. version, giving completeindependence from electric power.

Secured by means of self-lockinghandles, the screen can be replacedwithout the use of tools.

On one side of the machine is a spiretlevel to indicate the correct inclination. The inclination determinesthe flow velocity and thickness of thegrain layer on the screens - andfurthermore the cleaning efficiency.

The combi-cleaner is easy to service. Replacement and tensioning of belts arequickly effected by means of the special belt-tensioning system.

ApplicationsThe Kongskilde combi-cleaner typeDPC 40 is a combined screen andaspiration cleaner with capacities ofup to 40 t/h.Ideal for the pre-cleaning of maize,barley, Wheat, rye, peas and beansas well as for grading of malting bar-ley and seed.The combi-cleaner may be advantageously installed to allowcrop passage immediately after inta-ke and before discharge.

DPC 40 pre-cleaning - theadvantages:• Impurities removed before drying:

Impurities reduce drying rates,increase drying costs.

• Impurities removed before storage:A second pre-cleaning before thecrop is stored will remove impuri-ties which might result in deterio-ration of the sample.

• Reduction of dust:The aspiration action of the combi-cleaner reduces the level of dustcontamination, both before andafter drying.

• High capacity:With high capacity of up to 40 t/h,pre-cleaning places no restrictionon the rate of grain within theplant, even when bulking out fordelivery to merchants.

• Selling:A cleaner sample commands ahigher selling price.

• Mobility:The transport equipment (acces-sory) enables the DPC 40 to bemoved from place to place withcare.

DPC 40 cleaning and separation of malting barley- the advantages:• The malting barley can be delivered

completely clean from the plantgrower.

• You can make use of small grainsfor fodder.

Cleaning/Grading of malting barley and seedrequires roller brush to clean outer screen.(Optional extra).

Mode of operationUnclean grain flows down the inletduct, (1), into the rotating innerdrum screen, (2). This drum isconical, tapering away from theinlet. This reduction in diameterslows the movement of graintowards the far end, ensuring thatall grain and small impurities passthrough. Oversized impurities areejected at the end of the innerdrum, falling into the trash auger,(4). Small impurities pass throughthe outer screen, (3), and fall intothe trash auger trough. The grain ispicked up by an elevating scoop,(8), at the drum end and deliveredto the aspiration chamber, (9).Finally, the cleaned grain isdischarged through an OK 200outlet, (10). Dust and light impuritiesare drawn by the aspiration fan,(6), into the trash blow line. Fanaction is varied by adjusting the airbleed, (11). Screenings can be delivered, via aventuri, (7), into the trash blow lineor, alternatively, discharged viagravity outlet, (7), and/or, (12).

Impurities separated by screens andaspirator discharged into the trashblow line.

Impurities separated by screens andaspirator discharged separately.
