Four qualities of lightweight expanded refractory aggregate, EFG, EFG Low Iron, K25 and REFAG are manufactured at the Kingsley factory of Alfa Aggregates Products Limited.

Manufacture

Specially selected Fireclays are sintered on a moving hearth to form a porous ceramic Sinter. Following a cooling period, the sinter is crushed and screened into fractions thus producing a range of grain sizes to suit market requirements.

The Alfa refractory aggregates have low bulk density, high thermal insulation and refractoriness. All grades are sold world-wide for a range of applications.

Applications

Insulating refractory concretes for casting and gunning Additions to clay mixes to produce semi-insulating firebricks Back up insulation as loose fill and no-fines concretes High temperature ladle cover compositions Filler for ingothead tiles in steelmaking Filtration

Packing

Polythene valve sacks 20-25kg each depending on grain size, shrink wrapped on pallets 1.0-1.2 tonnes per pallet IBC's 1.0-1.2 tonnes per bag. Also half size bag available Loose bulk available in bulk tipper or silo tanker

Special packing available to customer specification by arrangement.

Export

Export to many countries is carried out by using selected pack sizes to achieve full payload.

Containers to deep sea destinations are filled to capacity to minimise shipping costs. 40ft containers can be filled with IBC's or palletised sacks.
