Feb 12, 2017· Ball Mill Grinding Circuit. Even though many ores require fine grinding for maximum recovery, most ores liberate a large percentage of the minerals during the first pass through the grinding unit. Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding.

The mill was a conventional leach-CIP circuit. The ore was crushed to 3/8" with standard- and short-head cone crushers. The crushed material was fed to one of two grinding circuits (A-circuit = 3 ball mills, B-circuit = single ball mill). A-circuit was one of the first in the world to include the fully automated Knelson (gravity) concentrator.
competent ores scheduled for 2017 and 2018. The Operation's comminution circuit, which comprises of a semi-autogenous (SAG) mill and two ball mills, each with 13 megawatts (MW) of installed power, was expected to be SAG mill limited when treating competent basement rock.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet ...

The Rock Creek mill is located just outside of Nome, Alaska. The mill was built to process 7,000 tonnes per day, and includes a three-stage crushing plant, gravity circuit, ball mill.
The mill was a conventional leachCIP circuit. The ore was crushed to 3/8" with standard and shorthead cone crushers. The crushed material was fed to one of two grinding circuits (Acircuit = 3 ball mills, Bcircuit = single ball mill).
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
Given that mills are charged to the target ball charge with reasonably sized media, and the feed to the ball-mill circuit is not so coarse as to cause constant scatting, the key to efficient ball-mill circuit operation is efficient classifier operation. The standard classifier for ball-mill circuits is the hydrocyclone.
