When looking for versatile manufacturing equipment capable of producing granules, rotary drums are often the equipment of choice. However, confusion frequently arises in choosing between an agglomerator and granulator. Because rotary drums are flexible in design and capable of processing large capacities, they are extensively …
Rotary granulators are a flexible processing tool ideal for high capacity applications. Frequently used throughout the fertilizer and mining industries, rotary granulators are commonly employed in the following types of applications: FEECO’s rotary granulators offer a variety of customizations, from various liner options to numerous …
Our photo this week shows an NPK fertilizer granulation plant. The photo was taken around the early 1960s and showcases a rotary dryer (the larger drum on the bottom), and a granulation drum (the smaller one above the dryer). Now a typical NPK granulation process, …
Granulation can be considered the same as pelletization, the method of agglomeration or particle size enlargement, but it often refers specifically to applications within the fertilizer industry. Granulation is generally carried out in a granulation/agglomeration drum if a chemical reaction is involved. The process works …
This week’s Photo of the Week shows FEECO founder, Jim Madigan (right), and son, FEECO President, Dan Madigan, posing next a rotary drum awaiting shipment. The rotary drum, ready to ship across the United States, was affixed with a banner showcasing that the drum was …
This week’s photo illustrates the build-up, or sticking of material in a granulation drum. Granulation drums, used in the fertilizer industry, can be prone to build-up on the interior of the drum for a couple of different reasons. Often times, the material or binder can …
Rotary drums, whether serving as a dryer, cooler, kiln, or otherwise, are essential process components in many industrial processes. In addition to being operationally critical, they also represent a significant capital investment. As such, prolonging rotary drum life through preventive maintenance is a key priority …
A rotary drum is the backbone of many types of rotary equipment, including dryers, coolers, kilns, and granulators. While the type of rotary equipment will dictate a number of key features of the unit, the rotary drum itself consists of several standard components that allow …
Continued from Part 1: Controlling Buildup in a Drum Abrasion and Corrosion Aside from buildup in a drum, abrasion and corrosion are also common challenges faced by many rotary drum owners. Though abrasion and corrosion can wreak severe havoc on a rotary drum if left …
Rotary drums are widely used throughout industrial production facilities to accomplish a variety of objectives, including drying, cooling, granulation, coating, and more. While rotary drum equipment is recognized for its reliability and longevity, challenges can arise, with the most common being buildup, corrosion, and abrasion. …
