Rotary dryers, rotary coolers, rotary agglomerators, and rotary kilns are a key component in many manufacturing processes, and making sure they run safely, and efficiently is crucial in any process. As a leader in the manufacturing of custom rotary dryers, rotary coolers, and rotary kilns, …
FEECO’s durable equipment has found its place in many industries, but the latest, is the frac sand industry. Frac sand is the latest craze in the Midwest, and as companies look to mine this valued silica sand, the FEECO sand dryer, along with other equipment, …
The following article was featured in the Sept/Oct issue of “Fertilizer International.” More Than An Equipment Company As a pioneer in rotary drying technology, FEECO International was founded in 1951 to supply the fertilizer industry and a variety of companies in the chemical processing, mining, …
Frac sand drying may seem like a simple task, but there is much more to it than meets the eye. When it comes to frac sand drying, there are a lot of factors to consider throughout the processing of the proppant sand that will dictate …
The refractory in a direct-fired rotary kiln is a crucial component, serving to both protect the shell of the drum and combustion chamber from the high interior temperatures, and to minimize heat loss. As a result, protecting refractory is not only critical to promoting optimal …
After a material is chosen for your rotary kiln refractory, you must decide the desired heat loss. When efficiency is of concern, or very high temperatures are involved, often it is desirable to use multiple layers of refractory: a “working” layer, and an insulating layer. …
Refractory is what protects the shell of a direct rotary kiln from the heat within, so as you can imagine, choosing a quality refractory that is right for your material is extremely important in the design of a rotary kiln. Choosing a refractory that will …
Holding the appropriate temperature within a rotary kiln is what allows the desired chemical reaction to occur. Sustaining that temperature, however, can be difficult if the right seal is not chosen. Almost all rotary kilns run at a negative pressure, meaning gas doesn’t leak out, …
Rotary kilns are integral to modern industrial processing, providing a controlled means of initiating chemical reactions and phase changes. As they are highly flexible and can be used to process hundreds of different materials, optimizing the performance of a rotary kiln around the process and …
Rotary kilns can be configured to fit nearly any process need, with a variety of customizations available to engineer an optimal processing solution. One customization that helps to promote efficiency in an indirect kiln is the bed disturber. Why use a Bed Disturber Indirect rotary …
