Design Features of the AURY screen

• AURY screens are manufactured in-house in our own ISO9000 quality certified manufacturing facilities.

• The entire manufacturing process is quality managed, and all components are tested throughout manufacturing process to ensure that final components meet AURY’s quality standards.

• AURY screens have been designed to be exceptionally structurally sound, and extensively tested and tuned to eliminate stress induced cracking.

• Side plates are weldless and assembled using Huck bolts to ensure minimal stress on the structure.

• Exciter beams are box beam construction designed using FEA software and design tested using strain gauges to ensure trouble free operation over many years.

• Exciter beams are constructed using automated “Submerged Arc” welding technology, and all welds are “Full Penetration”.

• Exciter beams are bolted using high tensile bolts and locking nuts.

• Heavy duty bearings by internationally recognized brands are used on the exciter for extended service life.

• Exciter castings are machined and inspected in house on high precision CNC machining centres. Almost all other exciter components are manufactured and machined in house to exacting standards.

• All exciters are test run for 24 hours while bearing temperatures are constantly monitored to ensure reliable long operational life.

• All fabricated steelwork is constructed from high grade and quality certified steel materials.

• AURY screen cross beams feature innovative and proven designs, consisting of tubular steel beams with full penetration welded flanges. Deck support fixing is via a cast steel saddle, which is machined and then Huck bolted to precisely and solidly mate to the cross beam.

• All exciter and cross beams are heat treated to eliminate stresses induced by welding.

• Assembled cross beams are abrasively blasted to SA class 2.5 and then sprayed with two coats (6 mm total thickness) of high-quality polyurethane to provide both corrosion and abrasion resistance for the life of the cross beam.

• All cross beams and exciter beams are machined to the precise length to ensure a solid and rugged final screen assembly.

• All screen stiffeners and bracing are primed before fitting and sealed using polyurethane sealer to provide high quality corrosion protection.

• All screen fabricated components are abrasively blasted to “bare metal” class 2.5 and then painted with a 2-part epoxy primer to 50 μm DFT and high build 2 pack finish coat minimum 150 μm to a final total minimum DFT of 200μm, providing exceptional corrosion protection.
