When working with a rotary dryer or kiln, the sealing mechanism is a critical component in the overall performance of the unit. Sealing mechanisms create a seal between the rotating drum and the stationary housing, preventing air or process gas from leaking into the system. Continue reading →
The biomass industry has seen steady growth the past few years, as nations around the globe continue to shift focus toward more renewable energy sources. And while biomass offers direct uses in itself, it can also be converted to a number of carbon products, all Continue reading →
Soda ash, or sodium carbonate (Na2CO3), is a versatile alkali material, critical in the production of a litany of products and materials. From detergents and chemicals, to consumer products and water softeners, this material can be found in many of the products we interact with throughout Continue reading →
This week’s highlighted resource is a brochure on FEECO’s rotary dryers and coolers. As a leading provider of custom rotary dryers and coolers, the FEECO brochure highlights options for both direct and indirect units for drying and cooling nearly any bulk solid material.

Within the thermal processing industry, there are two informal types of rotary kilns: commodity kilns and specialty kilns. Commodity kilns are kilns that are employed in widespread commercial use. Their processes are well developed, and have been in use for generations of commodity processing. Specialty Continue reading →
Catalysts are an irreplaceable tool in a wide range of industrial processes, from chemical synthesis to petroleum refining, and sustainability improvements, to name a few. Catalysts continue to play an increasing role in meeting the burgeoning demand for advanced materials and resource maximization that the Continue reading →
This week’s photo shows a warped leaf seal. Extreme heat during a kiln’s operation caused the seal to curl away from the drum, and cool into this deformed shape. It was later replaced by a FEECO Aftermarket Engineer. Leaf seals minimize air leakage into the Continue reading →
Rotary kiln air flow configuration is an important consideration in kiln design. Counter current and co-current are the different types of air flow options available, each offering distinct advantages and disadvantages. In co-current air flow configuration, the material and process gas flow in the same Continue reading →
This week’s highlighted resource is a Slideshare presentation on the production of activated carbon through the pyrolysis of biomass. Processing biomass through pyrolysis can yield a variety of end products, from biocoal and biochar, all the way to activated carbon, with additional products in between. Continue reading →
Touted as a miracle material, plastics have revolutionized modern society in countless ways; they keep our food fresher longer, they ensure medical devices remain sterile, and they make up many of the products and devices we use throughout our daily lives. But while plastic has Continue reading →
