Fortis IBA Ltd (Fortis) are a leading UK Incinerator Bottom Ash (IBA) Processor with over 12 years IBA processing experience. The business invests in the latest technology to ensure quality secondary aggregates are produced and distributed into the construction industry to reduce reliance on primary aggregates.
As a country, we are facing a limited availability of primary aggregates and IBA Aggregate plays a key part in for highways and construction projects as well as being a part of the solution for our country’s waste. For every one tonne of IBA Aggregate used in construction, approximately 400 black bin bags are successfully diverted from landfill. IBA Aggregate been approved as a sustainable alternative to Type1/6F4/6F5 by the Environment Agency, Highways England and local authorities such as Hampshire County Council and has been widely used within the construction industry for over 20 years.
The processing aspect of the plant is as follows:
The IBA material is transported from the Greatmoor Energy from Waste Facility which is located close to the Fortis site. This material is then stockpiled for several weeks, until it matures, and the moisture content has decreased sufficiently to allow processing. The feed material which is Approximately minus 150mm is fed into the first Warrior 1400x which is fitted with patented self-cleaning fingers separating the material into three different sizes. The oversize material, in this case +55mm, is sent to a mobile picking station where pickers retrieve Non-Ferrous items then an overband magnet removes any large Ferrous items.
The mid-size product of +20-55mm material comes off one of the side conveyors, fitted with an overband magnet and further separated with an Eddy Current Separator to remove any remaining Non-Ferrous and Ferrous materials. The <20mm material will then move up through a specially covered conveyor and into the second Warrior 1400x screen fitted with 28mm breaker deck and 6mm self-cleaning bottom deck. the material into a further two sizes. The <6mm material will flow into an All Metal Separator and anything >6mm will go right through to the front end and into a final All Metal Separator- with any metals left removed for resale.
Alan Rudd, Unit Manager, at Fortis offers his thoughts on the two Warrior Screeners:
‘’I like how mobile the two machines are and they are very easy to use, our operators have had no problems in getting to grips with operation and giving us very good access for any routine maintenance and cleaning. The machines are perfect for the application we are using them for and have been very reliable to date.”
