Sintering: Circular Sinter Cooler

The circular sinter cooler is a revolutionary system designed to tackle the critical challenges of enhancing operational performance, energy efficiency, and environmental sustainability in the sintering process. Developed by Primetals Technologies, this innovative cooler integrates state-of-the-art technologies to optimize the sinter cooling process, while simultaneously reducing emissions and energy consumption.

The circular sinter cooler stands out for its innovative features, which significantly enhance the efficiency of the sinter cooling process. Equipped with a high-efficiency waste heat recovery system, it captures and repurposes thermal energy, thereby reducing overall energy consumption and greenhouse gas emissions. The advanced design of the cooler hood effectively minimizes dust emissions, ensuring compliance with stringent environmental regulations and contributing to a cleaner, safer working environment.

A key feature of the circular sinter cooler is the patented charging chute, which optimizes the segregation of sinter particles across the sinter bed. This innovation enhances the cooling process by ensuring a uniform distribution of sinter, thereby improving heat transfer and cooling rates. Consequently, the system achieves lower sinter discharge temperatures and increased overall efficiency. By integrating environmentally friendly features and innovative designs, Primetals Technologies provides clients with solutions that meet the highest standards of efficiency, sustainability, and performance.
