Challenges in Limestone Processing

Limestone Drying Limestone Processing Issues: Abrasive and Prone to Clumping. A drying process is often used to precondition limestone rock for subsequent manufacturing steps. Like most rocks, limestone is abrasive as a raw material. As a result, heavy-duty rotary dryers are recommended to handle limestone’s abrasive characteristics.
