This week’s photo highlights material processed in a pugmill mixer. Pug mills, also known as paddle mixers, are industrial mixers used to condition, mix and agglomerate materials often in the presence of a binder. The pugmill mixer’s dual shafts with pitched paddles create a kneading …
Our photo this week is a damaged thrust roller. Damage occurred because the thrust roller either stopped rotating, and the rotary drum ran hard against its left side. The thrust could also have become damaged as a result of a bearing failure; the bearing may …
This week’s photo shows a damaged rotary drum tire. Tires can become damaged if: They are worn too thin. The mounting blocks get worn, causing excess tire creep and movement. The shell is distorted from over heating/cooling the drum. The tires are shimmed too tight. …
This week’s photo highlights a pan pelletizer’s binder spray system. The spray system, or nozzles, are used to disperse binder. Non-pressure agglomeration technologies, such as pelletizing on a pan pelletizer (also known as a pan granulator or disc pelletizer), often requires the assistance of a …
This week’s post highlights a series of images: rotary tire wear patterns. A rotary drum tire is a support structure for the drum, and provides a place for pressure to be absorbed. As with any piece of equipment, they must be inspected and serviced, if …
This week’s photo shows coal fines (left) and coal pellets (right). The sample was agglomerated in FEECO’s state-of-the-art Innovation Center. The Innovation Center allows customers to test their material at batch and pilot scale, in order to establish the equipment setup and parameters necessary to …
This week’s photo is a compactor from the FEECO Innovation Center. Here, a heat lamp is set directly on the compactor’s feed chute, so the metal of the cold chute would not take away the heat from the pre-heated feed material. FEECO’s process experts are …
Today’s photo highlights a girth gear (left) and gear lubrication nozzle (right), both components of a rotary drum. The gear drive assembly is mounted on the outside of the shell circumference. It meshes with a small gear drive, and causes the rotary drum to rotate. …
This week’s photo highlights a rotary dryer combustion chamber from FEECO’s Fabrication Facility. In regards to rotary dryer components, the combustion chamber houses the combustion reaction. From here, the drying air is directed through the rotary drum. FEECO offers a variety of combustion chambers including …
This week’s photo highlights an agglomeration test in process at the FEECO Innovation Center. Pellets on a disc pelletizer are pictured. The FEECO Innovation Center is equipped for both pressure and non-pressure agglomeration tests on either a single piece of equipment, or in a continuous …
