Generally speaking, rotary dryers are the sand dryer of choice when it comes to frac sand, offering many benefits over other drying options. One reason rotary dryers are chosen over other dryer types is for their ability to accept large throughputs. Rotary dryers are high …
In this week’s photo, a crane is hoisting a rotary dryer onto a semi-truck bed. The semi-truck will travel at night from Green Bay, WI to Lacrosse, WI, and from there, will be loaded onto a barge. The dryer will then make its way down …
This week’s photo shows the interior of an indirect-fired rotary kiln. Indirect kilns are used in various process settings where the processing environment must be tightly controlled, such as when processing materials that cannot be exposed to oxygen, or materials that must remain sterile, as …
Our photo this week comes from the FEECO Lab, and showcases the lab’s pilot scale indirect kiln. Indirect kilns are used for a variety of applications and materials. In general, there are a few reasons why it may be desirable to utilize an indirect kiln …
This week’s photo shows pellets inside of a rotary dryer. The image was taken at FEECO’s lab testing center, where dryers are often used both prior to and post agglomeration processing. Feedstock must be within an ideal moisture range in order for agglomeration to occur. …
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 …
