Catalysts continue to play a growing role in modern industry, carrying out an array of processes that otherwise might not be possible, promoting more sustainable industries through efficient processing, reducing toxic emissions, and more. As the use of catalysts grows, so too does the amount …
Rotary kilns, like any other high-performing piece of equipment, need regular inspection and maintenance to ensure ideal operation. The list below highlights the areas of a kiln that should consistently be inspected: Refractory. Direct heat can cause the kiln’s refractory to become tremendously dry, …
The trunnion wheel, also known as a trunnion roller, is a key structural component of any rotary drum base. What trunnion wheels are available? FEECO supplies trunnion wheels in 4140 or 4340 stainless steel. Sizes are available all the way up to 48” in diameter. …
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 …
Rotary kilns use extremely high temperatures combined with controlled retention times to cause a chemical reaction or phase change in a material. At certain temperatures (different per each material), a material will undergo a chemical reaction or phase change. This is often necessary to bring …
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 …
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 …
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, …
