Question of the Week: What is the Importance of a Sieve Analysis During Agglomerate Feasibility Tests?

This article was authored by:

Jenny Seim
Technical Writer

A sieve analysis measures particle size distribution, and more specifically, what percentage of on-size, over-size and under-size pellets are produced from the agglomeration process. The analysis is an important part of agglomerate process and product development, as it confirms whether or not the agglomeration process Continue reading →

 

Question of the Week: What is the Difference Between Hygroscopic and Hydrophobic Materials?

This article was authored by:

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 Continue reading →

 

Question of the Week: How does the Binder Spray System Affect Pelletization?

This article was authored by:

Jenny Seim
Technical Writer

Pelletizing on a pan pelletizer requires the help of a binding agent to achieve agglomeration. This is accomplished through the use of a spray system. The binding agent, and the way it is dispersed, plays a role in successful agglomeration. The following variables should be Continue reading →

While training is the cornerstone of many successful processes, it is especially critical when working with a disc pelletizing system. Pelletizing material on a disc pelletizer is considered a blend of both art and science; a number of variables must be balanced to maintain consistent Continue reading →

 

Photo of the Week: Seed Pellets

This article was authored by:

Jenny Seim
Technical Writer

This week’s photo shows seed pellets from a batch disc pelletizer 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 where it Continue reading →

 

Photo of the Week: Before and After Processing in a Batch Pin Mixer

This article was authored by:

Jenny Seim
Technical Writer

This week’s photo highlights a material before and after processing in the FEECO Innovation Center’s batch pin mixer. Pin mixers are adept for mixing, agglomerating, conditioning, micro-pelletizing, and de-dusting applications. The intense spinning action allows them to densify material and create small pellets, an ideal Continue reading →
