Optimum milling solutions begin with choosing the 1ight mill. In consultation with the mill manufacturer, selecting the right mill involves careful consideration of the appliion parameters (in this case, materials generally in the 2 to 4 mobs hardness range and up to 500 tn/hr capacity) and the various mill types available
