Question of the Week: What Role does Drying Play in Non-Pressure Agglomeration?

This article was authored by:

Jenny Seim
Technical Writer

Drying plays an important role in the non-pressure agglomeration process, both before and after agglomeration. Pre-Drying Drying is often used as a method of pre-conditioning material before pelletization, to help prepare the material for agglomeration. Since moisture is added during the agglomeration process (in the Continue reading →
