Some recent project highlights include delivery of a Kreyenborg Infra-red dryer to Irish sheet producer FOAMALITE (www.foamalite.ie)
We have delivered an energy efficient infra-red drum for the Crystallizing and drying of PET flakes that is installed in a new multi million Euro installation of a complete sheet extrusion line at Ireland’s specialist sheet extruder FOAMALITE Loch Gowna site. Kreyenborg Infra red drying technology is widely acknowledged as the leading system for the rapid crystallizing and drying of PET. Not only for virgin PET
pellets, but also for a variety of mixes through to 100% regrind sheets.

United Kingdom based specialist compounder, AURORA Manufacturing, have installed a new Compounding line including completely automated backflush KREYENBORG screen changer, BKG Pelletizing system and BSG ONE extrusion line control. The Leigh, Lancashire based compounder and recycler is using the backflush screen changer to ensure that high quality PP Compounds are produced efficiently with no need for the operator to make frequent screen exchange. AURORA feed the line with PP Flake from a variety of post industrial production scrap, the feed material can at times contain the metal threaded bushes from injection moulded parts. Previously with a conventional lantern ‘slide plate’ type screen changer these metal parts can lead to an extremely short screen life, with the operator having to frequently exchange screens. The new Kreyenborg screen changer is completely automated and reacts to varying levels of contamination. The differential pressure is monitored, and once the pressure reaches a pre-defined level, the system initiates the automatic backflush process – without the need for an operator to attend to the line. The backflush process automatically cleans the screen packs and ejects the dirt particles out of the screen changer housing. An excellent demonstration of this backflushing process can be seen in the 3D Video animation below.
As part of the new compounding line project for AURORA REGIS MACHINERY also supplied a complete BSG ONE extrusion line control system (www.bsgcontrols.com) that takes care of every aspect of the 90mm twin screw compounding line control. From the control of the screw speed and heating zones, to the automatic start-up process of the complete line (Including the Kreyenborg screen changer and BKG hydraulically adjusted underwater Pelletizer)

The PowerBackflush screen changer has proven to give superb automatic cleaning of the screens not only in PET applications but also with a wide range of other plastics.
In applications processing HDPE and PP the Power Backflush enables huge savings in costs associated with screen changing. The screen packs can be re-used this offers the advantage of
Dramatic reduction in costs for replacement screens
Dramatic improvement in utilization of operating personel
Dramatic reduction in costs for replacement screens each year
As the screen packs can be automatically cleaned by backflushing each woven wire screen pack has an extended life. This dramatically reduces the number of screens you need to purchase each year.
Dramatic improvement in utilization of operating personel
If you can imagine that with conventional screen changers every time the screens become blocked by contamination with traditional systems an operator must come and manually exchange screens.
With the POWERBACKFLUSH as the cleaning process is completely automated – Instead of the operator making 100-200 manual screen exchanges – He can be better utilized elsewhere in your extrusion plant. The automated backflushing will take care of screen cleaning each and every time the screens become blocked by contamination
Test results with a PowerBackflush screen changer -
In one trial the material was quite heavily contaminated therefore the system automatically cleaned screens by backflushing every hour. It was decided to stop the line and check the screens after four days of continuous running. On examination of the filter elements it was found that the screens had shown an extremely good level of cleaning With the result that there was still no need to change the screens even after 4 days of operation with highly contaminated material.

High quality packaging film is now manufactured from recycled PET on a new line at Sharp Interpack’s Bridgwater, Somerset site. The new line allows up to 100% recycled PET sheet to be produced direct from hot caustic wash plants.
The operation is now further enhanced with a Power Back-Flush (V-type)
screen changer from Kreyenborg GmbH- Germany that gives highly
efficient cleaning of the screen packs without additional pressure from
the extruder.
