Clay Testing FEECO International Inc.

Drying. Drying is a necessary step in creating many clay agglomerates, particularly when moisture is added in the form of a binder. The drying step reduces the moisture content of the agglomerates, hardening them into their final form, so they can move on to packaging or storage, or further processing, such as when a rotary kiln is employed.
