Liners provide a solution for steel versus polyurethane

Steel has, over the years, been incorrectly utilised in areas of high wear, assuming that its strength is the solution to preventing wear in high-impact areas – largely because steel and alloys were the only choice available.
But now, Polyurethane K-Redi liners are suited for use in high-impact, high-abrasive areas, at present outlasting all traditional wear-resistant products.
The K-Redi liner offers long-lasting wear protection for transfer points, chute areas, screen discharge points and bin lining. It is suitable for low-impact material handling applications where high abrasion and good slip characteristics are required, ideally in conveyors (particularly under chutes, deflector plates, skirt systems and aprons), mining (in feeders, skips and skirts) and ore handling and processing (bins, chutes, hoppers).
The K-Redi liner is a bolt in, polyurethane system that can be arranged into any wear pattern. It is also available with embedded alumina ceramics for extreme applications and offers higher wear factors and longer service life. Better abrasion and tear resistance can be achieved in localised wear areas by combining both the K-Redi liner ceramic modules and the K-Redi liner polyurethane modules. The K-Redi liner is also ozone and ultraviolet resistant, lightweight and easy to install, offering durability to reduce maintenance costs.
Case studies collected by Kinder & Co Pty Ltd are demonstrating that users are observing the difference between traditional steel wear-resistant liners and improved polyurethane K-Redi liners.
At Boral Recycling at Wetherill Park, Kinder?s K-Redi liner is being used in an application handling 220 tonnes per hour at 25mm<200mm of crushed bricks, asphalt and concrete from a drop height of three metres. This application previously used 16mm thick plate Bisalloy steel wear liners that lasted five months. The K-Redi liner is continuing to provide excellent wear capabilities and shows no sign of wear after installation in October 2010.
