Pin Mixer

Pin mixers are industrial mixing devices used to condition, agglomerate, and mix bulk materials, and work most effectively with fine materials such as powders. They utilize an intense spinning motion, in the presence of a binder, to produce small, dense agglomerates. Rods, or “pins,” are Continue reading →

 

Question of the Week: What is the Difference Between Pelleting and Pelletizing?

This article was authored by:

Jenny Seim
Technical Writer

Pelleting and pelletizing are two terms often used interchangeably, though their processing methods do differ. Pelleting commonly refers to the extrusion process, where cylindrical pellets are formed by forcing material through a die. It is most often used with wood, fuel and feed products (such Continue reading →

 

Question of the Week: How do you Combat Caking in a Rotary Dryer?

This article was authored by:

Technical Writer

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 Continue reading →

Technical Writer

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 material handling equipment used within an agglomeration operation: Application. Will the material be moving long Continue reading →

 

Question of the Week: What does a Typical Pelletizing Process Look Like?

This article was authored by:

Jenny Seim
Technical Writer

Pelletization is an agglomeration process whereby material fines are “grown” through a tumbling motion in the presence of a liquid binder or water. While all agglomeration processes can be customized to suit the unique needs of the material being processed, in general, it follows these Continue reading →

 

Question of the Week: How do Material Limitations Affect Rotary Dryer Design?

This article was authored by:

Jenny Seim
Technical Writer

Some materials come with limitations that will steer the rotary dryer design process in one direction or another. For example, with materials that have the potential for combustion in certain settings, a direct fired dryer would not be the ideal option; an indirect dryer should Continue reading →

 

Question of the Week: What is Granulation?

This article was authored by:

Jenny Seim
Technical Writer

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, and sometimes includes the addition of a pipe reactor Continue reading →

 

Question of the Week: What are the Common Reasons to Agglomerate?

This article was authored by:

Jenny Seim
Technical Writer

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 Continue reading →
