The two installed mills include a semi-autogenous (SAG) mill measuring 10.4 x 6.1 m with a drive output of 15 MW; and a ball mill rated at 18 MW. The SAG mill reduces ore fragments with a maximum size of 250 mm (P80 = 152 mm) down to 2 mm, and the ball mill reduces the SAG mill product to about 74 µm. Grinding is followed by flotation.
Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
