instead MELT PELLETIZATION has many benefits (high degree of agglomeration!)

There is less raw material lost as dust.
Animals can consume the feed more quickly.
Higher quality products.
Cost-effective production.
Easier handling, transportation, and storage.

The main methods for processing animal feed through agglomeration are pelletization and granulation. Pelletization is used most commonly, because it involves efficient mixing procedures that produce homogenous raw materials that are then agglomerated into pellets. The pellets produced in the process can be customized with respect to size, shape, and density.

Pelletizing methods and the quality of the pellets they produce are influenced by several different factors, including raw material particle size and composition, feed rate, and conditioning temperature. Materials with higher levels of fat content that were produced with lower conditioning temperatures tend to have lower overall quality, for instance. Other factors influence pellet quality as well, and often times, liquid binders are added to pelletizing machines in order to create stronger, more durable pellets.


**Agglomeration** is most well-known for its use within the food, mining, chemical, and agricultural industries. As part of the agricultural industry, or closely related to it, °**agglomeration** is also used in the animal industry, specifically to produce animal feed. By agglomerating animal feed, raw materials that are often dry, dusty, or in a form that is difficult to work with, such as sludge, are transformed into an efficient, easy to use product. The final product is often pelletized animal feed or granulated animal feed, with a number of benefits associated with both types of product, as well as a few different methods and pieces of equipment that can be used to produce them.

this coefficient maybe has to do with the pellet coating
