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 …
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 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, …
This week’s photo shows welders installing flights in a rotary dryer. FEECO has a respected name in the thermal processing industry, supplying customers with not only rotary dryers and coolers, but with rotary calciners and kilns too. Flights are located on the drum’s interior and …
This week’s photo shows waste paper sludge after it has been agglomerated and dried. This waste paper sludge comes from a paper recycling plant after having gone through processing to be reintroduced into the paper making process. Considered a waste, the paper fibers are too …
Sugar is a common product found in kitchens worldwide. From its familiar appearance to its unmistakable taste, commercial sugar of today is easily recognizable. But even a staple as basic as sugar requires a great deal of processing in order to create a consistent final …
Though rotary dryers typically use a hot gas stream to dry a material, sometimes drying a material requires a little more ingenuity. This is often the case when volatiles are present in the material to be dried and therefore a potential exists for combustion. While …
