Cycling and chemical incompatibility are the two main causes of refractory failure in a rotary kiln. Cycling Cycling is the heating up and cooling down of a rotary kiln, and it is the largest source of refractory failure. Refractory expands with the kiln as it …
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. …
Drying is a critical aspect of mineral processing; throughout the journey from ore to end product, the ability to control moisture content helps to reduce shipping costs, streamline downstream processing, and produce a refined product. While mineral dryers may appear the same as other industrial …
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 …
This week’s photo, taken in the FEECO Fabrication facility, shows a FEECO employee using a laser shaft alignment tool to properly align the coupling on the shafts of a drive assembly. The coupling joins the shafts between the drive motor and reducer. The shafts are …
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 best way to control material build-up in a rotary dryer is to prevent it in the first place. Custom Flight Design. Build-up can be prevented through the design of less aggressive flights, or material lifters. Material tends to build-up in sharp corners, and a …
