This company’s new Grate Kiln is a system engineered to produce premium-quality pellets that meet the demanding requirements of modern DRI (direct reduced iron) and low-carbon iron and steelmaking processes. Designed to ensure uniform mixing and heating, the rotary-killn technology used in the Grate Kiln system delivers consistent pellets with excellent physical and metallurgical properties, including high cold crush strength, optimal porosity, low temperature breakdown and strong reducibility characteristics. Engineered for optimal performance and low total cost of ownership, the new Grate Kiln system combines efficient process controls, advanced combustion technologies, improved heat recovery and digital solutions to enhance safety, efficiency and overall plant performance. The digital solutions for the Grate Kiln are designed to further improve process stability and product quality, while also reducing energy consumption. Typical improvements can include a several percent reduction in energy use and a more than 10% increase in pellet quality. — Metso Corp., Espoo, Finland
