Screening wood with a scalper K4

21 November 2012

The impossible proven possible, day after day

The general opinion is that it is almost impossible to screen wood into several fractions with a flat screen surface. At the company Filbois in Seraing, Belgium they prove otherwise day after day.

 

The site of Filbois is 47.000 m² and offers social employment to approximately 15 people. It is one of the missions of the company to offer social employment. The other missions are: recycling wood (for the chipboard industry and as an energy source) and remediating ground on their own site.

 

On the site of Filbois they recycle scrap wood coming mainly from waste collection centers. After unloading, the wood is sorted by quality. Using a rough, slowly rotating shredder the scrap wood is reduced to pieces of maximum 300 mm. In the following picking station, all contaminations, like plastic, metal, etc. are manually removed. The following hammer mill, reduces the scrap wood to a size of maximum 120 mm.

 

Recently the production of chipped wood is separated in 3 fractions using a Keestrack K4 -Novum, with extended main conveyor, resulting in a higher profit because of more specific end products. The general opinion is that it is almost impossible to sort wood in several fractions using a flat screen surface but with the right expertise, the right choice of screens, amplitude of the screen box and the right speed this is surely possible. This is proven every day at Filbois!

 

The hopper of the screening machine functions as a buffer and makes sure the screen is evenly fed. After fine screening into 3 fractions the middle fraction is used in the chip board industry, the oversize fraction will be reprocessed or be offered for energetic revaluation. The fines fraction serves as raw material for energetic revaluation. The approximate throughput of the K4 - Novum is 100 m³/hour.

Filbois in partnership with Ecoterres started in 2010 to remediate soil. Also for this purpose the Keestrack Novum is used. Changing the screen decks is done quickly and the Novum with its mobility can be utilized all over the recycling site.
