Rotary kilns (also known as rotary calciners) are used to heat solids to a predetermined temperature in a controlled processing environment in order to create a chemical and/or physical reaction. While rotary kilns have long been used in producing cement, their flexible capabilities have extended …
Though far less common than the need to dry or thermally treat a bulk solid material, some process settings call for preheating a material in preparation of downstream processing. In achieving this objective and meeting the high tonnages associated with bulk solids processing, rotary dryers …
Rotary dryers offer a highly flexible solution to drying bulk solids ranging from specialty chemicals to minerals and ores. But with all this flexibility and opportunity for customization often comes confusion on what configuration will provide the most efficient solution for the job at hand. …
Mineral dryers play a critical role in mineral processing, where controlling moisture content at various stages—from raw ore to final product—helps reduce shipping costs, improve downstream efficiency, and ensure a refined, market-ready material. Though they may resemble other industrial dryers, mineral dryers are specifically engineered …
Although it may seem like a good opportunity for cost savings, a one-size-fits-all approach to rotary dryer design typically yields a dryer that is ill-equipped, resulting in a number of unseen costs associated with product that is under-dried, over-dried, or in most cases, a mix …
Activated alumina is a form of aluminum oxide (Al2O3) with a myriad of industrial uses. A recent industry report by Grand View Research estimates the activated alumina market will see a CAGR of 5.4% up to 2025, largely as a result of its use in …
Rotary kilns are incredibly diverse in their processing capabilities, a characteristic that has pushed them into a growing number of applications. And while rotary kilns are reliable machines, they can experience issues, especially when not properly designed, monitored, or maintained. Knowing why such issues occur, …
In today’s industrial landscape, catalysts are essential for facilitating various processes, promoting sustainability, and reducing harmful emissions. However, the extensive use of catalysts leads to the generation of significant amounts of spent catalysts, which pose a unique set of challenges for waste management. As the …
As society continues to move toward more sustainable waste management methods, an alternative technique for handling EAF dust has been gaining interest: EAF dust recycling via reduction roasting. The Problem with EAF Dust EAF dust is a by-product of the steel production process, and refers …
The ongoing push to implement more sustainable practices continues to be at the forefront of every aspect of industrial processing. In this effort, high-temperature kilns, or rotary kilns, are turning out to be pivotal equipment in the effort to bring about positive change, both directly …
