Innovation at work Continuous quality improvement is a way of life for Weir Minerals. Our research and design teams continually work to develop better materials and product designs based on customer needs. J221 Material from Weir Minerals Silicon Carbide Polymer Ceramic J221 material from Weir Minerals is a uniquely designed Tungsten Carbide matrix which is metallurgically bonded to a 4340 substrate. It was designed for use on shaft sleeves to offer a significant improvement in sleeve and packing wear life where contaminated or poor flush water conditions exist. In mill circuit, oil sands or other severe duty applications, the J221 material is designed to be extremely durable, reduce downtime and increase mean time between failures. Weir Minerals has teamed up with a leading Silicon Carbide Polymer producer to develop components using this uniquely formulated material. This Silicon Carbide Polymer Ceramic, especially engineered for use in FGD applications, is unaffected by chemistry changes and is designed to provide the ultimate wear and corrosion resistance. Warman® Throatbushes with Pre-Swirl Vanes Warman® throatbushes featuring Pre-Swirl vanes take wear life and reliability to the next level. The innovative patent-pending throatbush design was developed to improve wear life of the impeller eye and reduce the re-circulative wear at the impeller throatbush interface. This is accomplished through a series of guide vanes in the pump inlet which induce a rotational velocity in the slurry. The Pre-Swirl guide vanes are designed to reduce the relative velocity of the slurry to the rotating impeller, improve the angle of incidence between the slurry flow and the leading edge of the impeller vanes and improve the uniformity of solids distribution in the slurry. This creates a smoother entry for the slurry into the impeller, which is designed to improve wear life, reduce downtime and provide superior reliability. Silicon Carbide Polymer (SiCP) is more corrosion resistant than white cast irons, making it ideal for handling duties that are both corrosive and erosive.
