A Terex Finlay 693+ Spaleck Supertrak machine, supplied by Finlay Plant Northern, is processing double the amount of IBA than seen previously at the facility in Haverton Hill, Middlesbrough. Processed IBA is used as a replacement aggregate in construction.

Norman Watson Haulage & Plant Hire is working at full capacity on site since investing in the new plant, with no downtime.

The company, operating from a 300-acre farm in Teesdale, has five loading shovels and now the Terex Finlay 693+ Spaleck Supertrak on hire in the Teesside, Tilbury and Sheffield area.

Managing director Norman Watson said: “Ash is a hard-to-process material and the meshes on the previous screener had to be pressure washed six times a day to clear them.

“The Terex Finlay 693+ Spaleck Supertrak was delivered six weeks ago and has never been blocked up yet. We’ve found that the amount of time it saves us is absolutely fantastic and means we’re able to process far more material than before.”

The plant, which has a double deck 20ft x 5ft Spaleck screen box, is fed with IBA, the residual product of energy recovered from household waste. Metals are extracted from the material beforehand and the rest is processed by the screener to create a sustainable source of aggregate diverted from landfill.

Three fractions are being produced by the Terex Finlay 693+ Spaleck Supertrak. The oversize is being used as sub-base and the middle size is for pipe bedding and pea gravel while the -5mm down is being sent to aggregate block plants for the production of concrete blocks for construction.

Charlie Nairn, managing director of dealer Finlay Plant Northern, said: “Norman Watson Haulage & Plant Hire came to us because their previous screener couldn’t cope with the damp material that needed to be processed. However the Spaleck heavy-duty vibrating screen optimises productivity of moisture-high materials.”
