Expanded clay aggregates, also called exclay, or lightweight expanded clay aggregates (LECA), are a beneficial material in a growing number of industries – most notably construction and horticulture, with water treatment and filtration applications likely next in line. The unique structure and physical properties of Continue reading →
Rotary kilns are used across a number of industries to cause a chemical reaction or phase change in a material. This high temperature thermal treatment can be used to carry out a variety of different objectives, from catalyst activation to aluminum decoating. The number of Continue reading →
Rotary kilns (also known as rotary calciners) are used to heat solids to a predetermined temperature in order to create a chemical and/or physical reaction. The two basic types of rotary kilns – direct fired and indirect fired (calciners) – can be found supporting processes in Continue reading →
The ongoing push for implementing more sustainable practices continues to be at the forefront of industry. Increasing regulatory action, combined with an ethical responsibility, has forced industries of all types to investigate a more sustainable approach in every aspect of their business if they want Continue reading →
Rotary drums, including dryers, coolers, and kilns, are an integral part of the many industrial processes that shape our world. From fertilizer and chemical production to ore beneficiation and even consumer products, rotary drums provide a reliable, high-capacity setting for accomplishing a number of necessary Continue reading →
Rotary drums can be configured to serve as a variety of different pieces of equipment, including a rotary dryer, cooler, kiln, granulator, or even a coating drum. With such diverse employment, these robust systems can be used to accomplish a variety of goals across a Continue reading →
Indirect rotary kilns, or rotary calciners, offer three major advantages over their direct-fired counterparts, as outlined below. When processing in a direct-fired rotary kiln, fine materials can become entrained in the gas and carried out to the baghouse. An indirect kiln avoids this issue because 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 →
Biocoal, a product produced by thermally upgrading biomass, has been gaining traction throughout the world as countries look to more renewable energy sources in an effort to reduce dependence on coal and mitigate greenhouse gases. What is Biocoal? Biocoal, also commonly referred to as syn Continue reading →
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 Continue reading →
