Disparate materials can often clump together, or stick to the interior of the rotary dryer during the industrial drying process. This is referred to as unwanted agglomeration, or caking. Caking can occur for many reasons, but most often is the result of material characteristics that foster …
Vibration can be caused by many different components on a rotary drum. A high percentage of the time, it comes from the drive, and most commonly, the gear engagement. But vibrations can also generate from the tires of the drum if they have developed a …
The potential for red mud re-use and/or recovery applications are extensive, with challenges such as high alkalinity, heavy metals, and colossal quantities at the forefront. Common re-use and recovery undertakings can be seen below. Material Recovery. Red mud is a waste abundant in resources; it …
Bulk material handling equipment moves raw and processed material from one location to another throughout the agglomeration facility. To effectively transfer the material, the following should first be evaluated when designing bulk material handling equipment used within an agglomeration operation: Application. Will the material be …
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 …
Agglomeration is commonly used to upgrade material fines into a granular product. It can also be used to transform sludge-like materials into a dry, granular form. There are many reasons to agglomeration a material. The choice to agglomerate often stems from a material problem, be …
Advancing flights and knocking systems are two common rotary dryer add-ons. Advancing Flights. Advancing flights work to move material into the dryer, to prevent build-up near the wet feed discharge. Additionally, advancing flights also give material the chance to dry before it moves on to …
Agglomeration is the process of particle size enlargement, and is used to collect material fines into a larger, unified particle. Seen throughout an extensive range of industries, agglomeration can transform dusty or difficult to handle materials into a more manageable form. While many factors should …
Due to their flexibility in processing virtually any bulk solid material, rotary dryers have made their way into an abundance of industries around the globe. The following is a brief overview of some of the most common industries FEECO’s rotary dryers are employed. Agriculture Selected …
Micro-pelletizing can be carried out in a pin mixer, or in a pin mixer/disc pelletizer (pan granulator) combination. Pin mixers alone often provide efficient results when full-scale pelletizing is not necessary, or when only smaller pellets or conditioning is needed. To begin, the pin mixer …
