Rotary drum granulators, also known as agglomeration or granulation drums, are pivotal to a wide array of industrial processes, helping producers working with bulk solids to condition and agglomerate their materials for downstream processing, easier handling, and improved performance. In selecting agglomeration/granulation equipment and evaluating …
This week’s photo shows seed pellets from a batch disc pelletizer (pan granulator) test in the FEECO Innovation Center. Many pelletization processes first begin by pre-conditioning fine powder with moisture; the material is pre-conditioned in a pin mixer, and then fed onto the disc pelletizer …
Pugmill mixers are relatively flexible devices, able to mix, condition, and agglomerate a diverse range of bulk solid materials. They are also adept at processing both liquid and solid feeds, and can be used as stand-alone pieces of equipment, or prior to processing in a …
Rotary kilns (also known as rotary calciners) are used to heat solids to a predetermined temperature in a controlled processing environment in order to create a chemical and/or physical reaction. While rotary kilns have long been used in producing cement, their flexible capabilities have extended …
This photo of the week shows the inside of a coating drum while in operation at the FEECO Innovation Center. Coating pellets is desirable for many reasons, including to control dust, caking, or moisture absorption, or to improve flowability of a material. Coatings are also …
The US has made an important step toward building a domestic supply chain of critical minerals with a recent commitment to mapping the nation’s resources. As one of the industry’s leading mineral processing equipment suppliers, we’re watching the situation closely. Here’s a look at what’s …
Pan pelletizer operation is oftentimes considered an art because of the many mechanical and process variables that must be properly combined to achieve the desired pellet characteristics. A trained operator is necessary to create the most efficient pelletization process, and the most ideal end-product. The …
Though far less common than the need to dry or thermally treat a bulk solid material, some process settings call for preheating a material in preparation of downstream processing. In achieving this objective and meeting the high tonnages associated with bulk solids processing, rotary dryers …
This week’s photo highlights one of FEECO’s many replacement/spare parts: the thrust roller. Thrust rollers are a standard component to any rotary drum, from rotary dryers and coolers, to granulators and kilns. They ride on the downhill and uphill edge of the tire, and are …
The process of sizing a rotary dryer is one of precise engineering involving complex calculations and meticulous design. While the process is not well simplified into a few paragraphs, an explanation can be offered as to some of the concepts behind the process of rotary …
