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 …
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 …
In 2015, the global fly ash market was estimated to be valued at 40 billion USD. A recent industry analysis by Research Nester anticipates the market will reach an estimated 70 billion USD by the end of 2023 – a 7.1% CAGR owing to increasing …
FEECO’s rotary dryers and kilns can accommodate numerous fuel sources. The chart below highlights the equipment and their available fuel source options: Natural Gas/Propane Fuel Oil Electricity Biomass Combustion Waste Heat Biogas Direct Rotary Dryer x x x x x Indirect Rotary Dryer x x …
A recent white paper by William Strauss, PhD of FutureMetrics LLC, looked at a strategy that could breathe life back into the dying US coal industry, and the answer comes from an unlikely place: implementing policy to support the co-firing of wood biomass pellets (biocoal) …
This week’s photo highlights a rotary dryer combustion chamber from FEECO’s Fabrication Facility. In regards to rotary dryer components, the combustion chamber houses the combustion reaction. From here, the drying air is directed through the rotary drum. FEECO offers a variety of combustion chambers including …
This week’s photo shows a combustion chamber under production in FEECO’s Fabrication Facility. Castable refractory is pictured in the center. Fiber modules surround the castable on either side; they are lighter and have a lower thermal conductivity. The fiber modules are not used on the bottom …
Rotary dryers are sized and designed around a material’s unique processing needs, or at least they should be. A custom rotary dryer will produce the most ideal results. The following material characteristics should be considered in sizing and designing a dryer: Moisture content, including inlet …
