Φ2700×4500
Ball Mill, Large Diameter
The Φ2700 to Φ3600 shells are the grinding end of a concentrator or cement line: 500 to 1600 kW of drive, 10 to 250 t/h of product at 0.075–0.6 mm. Same wet-or-dry principle as the smaller mills — the difference is scale, and the drive arrangement that comes with it. On this class the motor frame in the table tells you what you are buying: the TDMK and TM frames are synchronous machines on a center drive, the YR, JR and YRKK frames are wound-rotor machines on a girth gear. We confirm the arrangement on the drawing for the size you order, together with the foundation loads.
