Two chamber mills are used for grinding cement, slag and similar materials. They are typically arranged in a circuit with high effi ciency VTP separators. They grind materials up to 6500 cm2/g according to Blaine. The mill itself is equipped with a lifting armoring in the fi rst chamber with larger balls with a high comminuting effect.
