Advancing flights and knocking systems are two common rotary dryer add-ons. Advancing Flights. Advancing flights work to move material into the dryer, to prevent build-up near the wet feed discharge. Additionally, advancing flights also give material the chance to dry before it moves on to …
Amidst political uncertainty and increasing demand, gold has been making headlines as companies continue to invest in the safe haven metal. This state of affairs has had an especially significant impact on Australia, where a once-beleaguered industry is seeing a strong revival, so much so …
This week’s photo highlights several rotary dryers under production at FEECO. The photo was taken in FEECO’s fabrication facility, just shortly after our founding in 1951. For decades, many industries have been faced with the same problem: product moisture. Depending on material composition, moisture can …
Red mud is a byproduct of aluminum production, in which alumina is extracted from bauxite ore via the Bayer process. Unfortunately, for each ton of aluminum produced, around 1-2 tons of red mud are also produced, creating a massive amount of industrial waste to manage. …
Due to their flexibility in processing virtually any bulk solid material, rotary dryers have made their way into an abundance of industries around the globe. The following is a brief overview of some of the most common industries FEECO’s rotary dryers are employed. Agriculture Selected …
Today’s photo is a 3D combustion chamber. Combustion chambers are used to keep material from coming into direct contact with the burner flame in either a rotary dryer or kiln. The combustion chamber houses the combustion reaction, and directs the airflow into the drum. The …
Our photo this week is a sand dryer used in processing frac sand. The 8’-6” x 50’ long dryer utilizes co-current airflow to reduce the moisture content of mined sand. The rotary dryer contains an additional 5’ shell length to incorporate flame cut openings to …
Yet another application for biochar looks to be on the horizon; a growing number of studies are proving that biochar could be an effective tool in managing air quality, with one study finding that the charcoal-like material has the potential to significantly reduce air quality-related …
Today’s photo shows the interior of a rotary cooler. The material inside of the cooler is dried distillers grains with solubles, also known as DDGS. DDGS is a is a by-product of ethanol production, and can be used as an animal feed ingredient due to …
While nickel is perhaps most commonly known for its use in coins, it is also an important material in many industrial processes. Nickel’s high melting point, ductility, and resistance to corrosion when alloyed lends itself to a wide range of industrial applications and materials, making …
