Ajax Agitated Screw Feeder for Lianhetech Europe

Solids handling specialist, Ajax Equipment, has supplied leading fine chemical manufacturer, Lianhetech Europe, with an Alloy 22, extremely corrosion resistant high nickel alloy, agitated screw feeder for Lianhetech Europe’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.

“Following initial meetings and the specification of Lianhetech’s requirements, Ajax provided a bespoke design for the screw feeder and supplied the unit within the challenging timelines of the project. Ajax takes the time to understand the requirements of each specific process rather than supply a generic design and this is one of the key reasons that ensures the units can do the job from the start,” said Imran Khaliq, engineering manager, Lianhetech Europe.

“Ajax designs its agitated screw feeders to each customer’s process needs including the flowability of the material, required discharge rate and holding capacity,” commented Eddie McGee, managing director, Ajax Equipment. “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 which Ajax duly met.”
