With the KOCH metering device it is possible to meter material with an accuracy of up to 0.005 %.You can colour shotweights from 1 to 5000 grams and this – if required – using just one metering station. Every compact conveyor fits on all large metering stations and intermediate hopper units.

A simple calculation shows how important it is to use a good volumetric chamber device:

If only 1 % more masterbatch per 100kg/h than the required minimum is processed,and assuming that a 24 hour working day with 5 working days a week is in operation,at a cost factor of 10 per kilogram, it would result in approximately 60,000 extra costs per annum.

Exact metering saves 5,000 per month.

This means that the costs of purchasing a good metering device are very quickly recouped.

A metering roller fitted with smallchambers that are always evenlyfilled. A relief plate ensures thesame bulk density irrespective ofhow much material is contained in the hopper. An agitator and scraper guarantee optimum conditions for accurate metering

Liquid metering by means of a piston pump with ± 0.15 % accuracy

Powder metering with ± 0.15 % accuracy

Granulate metering with ± 0.15 % accuracy

Volumetric Chamber Metering

A piston stroke activates themetering process. An inlet andoutlet valve guarantee a meteringaccuracy of +/- 0.15 % per stroke

Each chamber of the metering rollermust be evenly filled before metering.Granulate protruding from the chambersis simply stripped off by a stripper plate.In addition, a constant rpm speed resultsin a high metering accuracy

Type KöGranular station for masterbatch With volumetric chamber metering to save on colour.

This granular station can be employed to meter additionalcolour with extreme accuracy.The quantity of the meteredadditive is continuously variable. Whether masterbatch, largeor small pellets, the metering roller has been designed to copewith them all and has performed outstandingly over the years.

Type PuPowder stationThe Type Pu metering station can be used to meter powder with extreme accuracy, up to 0.005 %.Colours can be changed quickly and cleanly.The powder station is of a simple and logical design and is reliable and easy touse: it has a metering roller with assisted discharge of its chambers, an agitator to move the powder and a screw to removethe roller for cleaning or exchanging.

Type MaRegrind station and granular station up to 200 kg/h

The ability to meter sharp-edged pellets without blocking themetering equipment is absolutely essential for continuousproduction.The regrind station achieves this by a star-feederof V2A steel. Absolutely leak-proof, with a central agitator anda side-mounted motor. A slider assembly at the bottom ofthe station provides for quick colour or material exchangewithout the need to dismantle any of the equipment.

Type SL 31Control unit for 1 station

Type SL 41Control unit for 2 stations

On injection moulding machines, metering and colouring isperformed in accordance with the work cycle of the proces-sing machine. By determining and entering the requiredmetering times for the individual components, it is possibleto colour smallest and largest shotweights of up to 0.005 %.All control units can be equipped with additional acoustic orvisual (flashing) alarms for added safety.

Type SLm 31 und SLm 41These control units also come with a micro-processor controller, input of the metering amount is effected in % with memory for stored recipes and LED display.

Type MCmMicro-processor control unit

The new generation of KOCH-MC micro-processor controlunits fulfils all customer requirements.All processes frommetering, colouring, processing capacity in kg with date,time, statistics, level control and possible fault monitoring are handled and stored for recall at any time. However, youcan also connect it up to a PC via an integral interface whichenables you to access the data from your office or to inputand change recipes in the recipe memory. Once you haveentered the recipe for the material to be processed youneed only input the desired percentage values and the metering quantity will be computed automatically by theKOCH-MC control unit. In this way several hundreds ofrecipes can be inputted and stored.A large LC display facili-tates data input.The internal constant value memory ensuresthat no information is lost.

Programming of the control unit is greatly simplified by logicuser-guidance.This makes the whole task simple and safe andsignificantly reduces the effort involved as these days instantaccess and evaluation of all operating data is no longer aluxury, but rather a necessity.

GRAVIKO Type GK 60

GRAVIKO

Metering and weighing gravimetrically, controlling, correcting and evaluating in one operation – and all this at a favourable price.

The individual components are metered into a weighing hopper by a slider or alternatively a star-feeder (volumetric chambermetering).The scale registers the actual weight of the individual components which is transferred to the KOCH controller andcompared with the calculated desired weight.The weighing for each filling is performed several times consecutively, and normalfluctuations are compensated by forming the mean value.

If the desired and actual weight coincide, the bulk goods are emptied into the mixer.

By combining the slider opening times with volumetric chamber metering it is usually possible to exactly meter up to ± 4 grainsper 1000. A control loop is created by combining the optional accurate volumetric chamber metering with the controlling andcorrecting gravimetric metering.This control loop guarantees an absolutely correct metering – independent of the bulk goods –with an accuracy of ± 3 grains per 1000.

The KOCH GRAVIKO program detects external interferen-ces as "tearaways” and disregards them in the comparison of the weighing results. Faulty metering due to external influences is then a thing of the past.

Gravimetric metering and weighing system (patented)

Graviko GK 60Processing capacity up to 60 kg/h

Depending on the metering station used up to 60 kg/h throughputcan be processed.The main components are added via a slider,smaller metering amounts via the proven powder, masterbatch orgranular station (Pu/Ma(Kö).

For metering and conveying, the modular principle is to be found atwork here too.All components are thoroughly mixed after weighing(see photo below right), before they are processed.

The GRAVIKO can be disassembled in two minutes without the aidof tools (left).

We supply a suitable control unit for each
