Our photo this week is a rotary dryer. Rotary dryers are used in a variety of industries to dry materials prior to transportation, baggage and storage. They operate at temperatures between 800° – 1400°F and use internal flights to maximize heat transfer between the material …
This week’s photo reveals the flights in a rotary cooler. The flights, also known as fins, are fastened to the interior of the cooler in order to increase heat transfer efficiency. Flights work by scooping up the material inside the drum and dropping it through …
Whether recovering a valuable component from waste, drying a precursor material, or performing a chemical reaction to yield an end product, establishing a safe, effective, and efficient thermal process often relies on thermal testing procedures like those carried out in the FEECO Innovation Center. Testing …
Our photo this week is a rotary dryer. Rotary dryers are considered to be the “workhorses” of the thermal processing industry, ideal for fertilizer, mineral, aggregate, industrial waste, and sludge drying applications. They’ve earned their reputation for their reliability in accepting variances in feedstock, and …
Our photo this week is a rotary cooler. Since 1951, FEECO has played a large role in the thermal processing industry, supplying customers with rotary coolers around the world for a variety of industries. FEECO’s coolers are constructed of a robust drum, and use chilled …
This week’s photo shows two cranes lifting and placing a rotary dryer onto a semi-truck’s bed for shipment to the customer. Though FEECO may be saying farewell to the dryer itself, this is just the beginning of a long-term customer relationship. FEECO remains committed to …
This week’s photo shows a rotary dryer under fabrication. A welder is finishing work on the top, before it gets painted and then delivered to the customer. FEECO is an experienced rotary dryer manufacturer, and has worked in the industry for over 60 years. Throughout …
This week’s photo shows two types of flights in a rotary dryer: standard lifting flights, and advancing flights. Flights, or lifters, are positioned inside the rotary drum and play a fundamental role in the drying process. As the drum rotates, flights lift the material, and …
Throughout various stages of a gypsum wallboard processing system, drying can be attributed as a leading element in the overall quality of a final gypsum product. Considering that gypsum wallboard sales exceeded $3 billion in 2013 alone, with sales estimates projecting rising demand, it comes …
This week’s photo shows two small rotary dryers with external metal pieces. The metal pieces, or ramps, serve as an early version of the “knocking” system to keep material from building up or caking inside the drum. When material enters the drum, the drum rotates, …
