Atex Compliant Solution Agitated Screw Feeder for Seal Sands Production
Ajax Equipment supplied an agitated screw feeder fabricated in Alloy 22 to Lianhetech Europe for its Seal Sands production site in the UK. Featuring numerous sight glasses for monitoring, the agitated screw feeder is also Atex compliant for Zone 1/21.
Ajax Equipment, has supplied leading fine chemical manufacturer, Lianhetech Europe, with an Alloy 22, extremely corrosion resistant high nickel alloy, agitated screw feeder for the company’s Seal Sands production site near Middlesbrough, UK.
The feeder receives batches of product from a centrifuge into its horizontal cylindrical hopper section fitted with a multi-bladed agitator that sweeps the body internal diameter and along the full length to disturb time consolidation and sweep product into an integral Lynflow ribbon screw feeder that extracts along the full length to regulate feed into the site’s dryer.
The agitated feeder is Atex compliant for Zone 1/21, category 2 equipment (inside and out) with N2 purge and was water fill tested as part of successful Factory Acceptance Tests (FAT) at Ajax’s Bolton, UK works. The agitated screw feeder also features multiple sight glasses enabling monitoring at several points, mentions the company.
Due to the process materials involved, the construction required Alloy 22 which is noted for its excellent resistance in a wide range of chemical environments. It is significantly harder than stainless steel so working to shape and of course polishing for smooth flow conditions was quite the task.
