There are various difficulties with theoretical modeling of a fluidized drum granulator owing to the mathematical modeling of the movement of fluidized solid particles. Many models are available for the movement of fluidized drums such as rotary drum dryers. This study examined the manufacturing process of dried ammonium nitrate. The process was …
spherical than those produced by pan granulators. Drum granulators were generally believed to require a lower recycle ratio than pugmills, due to a higher evaporation of water from the granules [2]. While the Spherodizer Drum produced high quality spherical granules with lower recycle, the process can be hard to scale up [6].

Introduction. Introduction of Rotary Drum Granulator: Drum granulator is a kind of machine can make the material into a specific shape. Drum granulator is one of the key equipment of the compound fertilizer industry. It is suitable for large-scale production of cold &hot granulation line and high and low concentration compound fertilizer line.
Abstract. The granulation process using rotary drums technology, is an essential unit operation to form good quality granules in many industries such as food processing, pharmaceutical, petrochemical and mineral processing. The main objective of this work is to study and analyze, by CFD approach, the dynamics of solid fertilizer …
Granulators Drum granulators are extensively used in the mineral processing and fertiliser industries. They are capable of very large capacity (see Table 8.1). In contrast to disc granulators, there is no size classification at the output. Drum granulators often run with large recycles of undersize and crushed oversize granules.
Founded in 1951 as the Fertilizer Engineering & Equipment Company, the name FEECO has become synonymous with fertilizer granulation expertise in every facet – from process development, to equipment design and …
The drum is gear driven and has a tilt angle of 2–3°. 2–4 mm granules with a moisture content of about 60–65% (for fertilizer) are obtained in the drum granulator.
Similarly to fluidized bed granulators, granulation loop processes using drum granulators also show oscillatory behavior of particle sizes and particle flow rates [29], …

Gas Sparger Design In Drum Granulators - posted in Industrial Professionals: greetings!!i am currently working on the design of steam and ammonia spargers to be installed in a rotary drum granulator, the type of granulators used in fertiliser granulation plants in the USA and Europe in the 1960s to 1970s.my …
The main objective of this work is to study and analyze, by CFD approach, the dynamics of solid fertilizer granules and the fluid phase, within an industrial inclined rotary drum granulator.
An experimental study was made of the drum granulation process, using various sizes of glass spheres as the material which was granulated. It was found that when the amount …
Rotary drum granulators are generally low maintenance, but some items can become worn, depending on the operating conditions, and particularly if the drum falls out of alignment. The most common wear items for a drum granulator typically include the liner (where applicable), tumbling flights (where applicable), and potentially trunnion wheels ...

Granulation drums work by tumbling material in a rotating drum, typically in the presence of a binder. The binder causes the fines to become tacky and allows them to pick up additional fines, forming agglomerates in a process referred to as coalescence. The tumbling action helps to round the agglomerates and create a homogeneous mixture.
