Cow dung arrives from the barn at 75 - 90% moisture. Mechanical dewatering removes the first half of that water cheaply, and a rotary dryer handles the rest when the final product must be dry powder or stable granules.

Shunxin supplies both stages: screw-press separators for mechanical dewatering and rotary drum dryers with matched hot air stoves for thermal drying. The combination minimizes fuel cost per ton of finished product.
