Process extreme products

Johnsons Aggregates and Recycling has put in a high-speed Terex Finlay 883 Spaleck to process incinerator waste ash.

The waste is being put through the machine at the company’s site in Nottingham to produce road construction materials.

Supplied by Finlay Central, the machine features a two-deck German-designed and constructed screenbox. The heavy-duty vibrating screen offers nearly blockage-free screening in the upper and lower deck due to 3D and Flip-Flow technology.

The 3D screening guarantees correct grain size, with no long pieces or extraneous material, for the tension shaft screen on the lower deck. The Flip-Flow screen, which has screwless mounted screen mats, avoids unnecessary cleaning.

By combining two systems in one machine, the 883 Spaleck offers significant savings on conveying equipment, steel structures and space.

Steve Johnson, director and founder of Johnsons Aggregates and Recycling, said: “The machine is versatile and can process extreme products that typically struggle through conventional screens.

“The additional vibration enables the ash material to release itself, so it avoids clogs, and it also handles the product’s abrasive consistency. The self-cleaning mechanism is also very useful.”
