Rotary kilns use extremely high temperatures combined with controlled retention times to cause a chemical reaction or phase change in a material. At certain temperatures (different per each material), a material will undergo a chemical reaction or phase change. This is often necessary to bring Continue reading →
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 Continue reading →
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 Continue reading →
The pin mixer is an industrial mixing solution ideal for mixing, conditioning, and agglomerating material fines in the presence of a binder. While the pugmill mixer (paddle mixer) is best suited for heavy-duty materials such as ores, the pin mixer excels in applications where extremely Continue reading →
Paddle 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 Continue reading →
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 Continue reading →
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 Continue reading →
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 Continue reading →
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 Continue reading →
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 Continue reading →
