Zinc (Zn) is a micronutrient essential for healthy growth in plants, animals, and humans. In plants, zinc fosters proper growth and development and is recognized as closely tied to limited crop yields when not available in sufficient amounts. Furthermore, malnutrition as a result of zinc Continue reading →

 

Photo of the Week: Dry Crush Strength Test- Before and After

This article was authored by:

Jenny Seim
Technical Writer

This week’s photo highlights a dry crush strength test from the FEECO Innovation Center. Crush strength tests measure the strength of a pellet, or how much pressure it takes to completely crush the pellet. The tests are performed on a single pellet, using metal plates Continue reading →

 

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:

Jenny Seim
Technical Writer

Simply stated, hygroscopic materials absorb moisture, whereas hydrophobic materials do not absorb moisture from the environment. Knowing which category a material falls under plays an important role in our work in the Innovation Center; it affects the way in which a material is both stored Continue reading →

 

Photo of the Week: Compactor with Heat Lamps

Technical Writer

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 →
