The grates are used for aluminium cans recycling.
Originally the grates were cut / fabricated from astralloy V plate. At that time the grates were not hardfaced and overlayed with tungsten carbide. The grates have been redesigned to be cut from
Hardox 450 steel plate and hardfaced with complex carbide overlay.
Grates Original Design ‐Astralloy V Plate / No Overlay = 3,000,000 Lbs/ 1.360.777 kg recycled aluminum before failure
Grate redesign ‐Hardox 450 plate / complex carbide overlay = 70,000,000 Lbs/ 31.751.465 kg recycled aluminum before failure
