Drying Limestone Pellets After Agglomeration. Since the pelletizing process typically uses a liquid binder to form pellets, drying is necessary after pelletizing to essentially "cure" pellets into their final form. This creates a stable, durable product, and helps to prevent issues such as mold growth and caking.
