Iron Ore Processing: From Extraction to Manufacturing
Grinding Mills: Grinding mills, such as ball mills and rod mills, are commonly used for grinding iron ore. These mills contain grinding media (steel balls or rods) that tumble and impact the ore, causing it to break into smaller particles. The choice of grinding mill depends on factors such as the desired product size, capacity …
