The flow properties of a bulk solid can have a significant impact on process efficiency and the success of the end product. And while bins, hoppers, and the like are often designed to minimize such issues, agglomeration can be a valuable tool in improving the Continue reading →
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 →
This week’s highlighted resource is a project profile on a coating drum for ammonium sulfate. FEECO supplied a custom coating drum for coating ammonium sulfate fertilizer granules. Testing in the Innovation Center supported the project. Click here to view the profile. To receive weekly articles, Continue reading →
Pug mills, also known as paddle mixers, are industrial mixing devices capable of conditioning, agglomerating, and mixing. Pug mills use dual counter-rotating shafts with affixed pitched paddles to create a kneading and folding over motion inside of the mixer. The counter-rotating motion lifts material up 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 →
A slowdown in manufacturing was a contributing factor in the Federal Reserve’s decision to cut interest rates by a quarter-percentage point for the first time in more than a decade. The slump, typically an indicator of wider economic trends, comes amidst the ongoing trade war Continue reading →
This week’s highlighted resource is a web page on conditioning. Conditioning is a diverse and valuable technique used to improve the handling qualities of bulk solids. This page provides an overview on commonly conditioned materials, the conditioning process, and the equipment typically used in conditioning Continue reading →
This week’s photo shows a sample of a rotary drum’s spare parts. A housing to the trunnion wheel bearings is pictured left, and a graphite block is pictured right. Bearings, graphite blocks, thrust rollers, drive sprockets and more are all recommended spare parts for rotary 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 →
A rotary drum in any industrial process setting, whether it is serving as a dryer, cooler, kiln, or agglomeration drum, is a critical component in the process loop; in most cases, if the rotary drum is offline, the remainder of the process must go down Continue reading →
