Rod mills, how they function - Mine Engineer.Com

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

Optimizing Performance of SABC Comminution Circuit of the ...configuration of the SAG mill and ball mill (both rated at 6000 kW with a single pinion drive). The capacity of the SAG mill was not fully utilized, as the actual operating power draw was only 3358 kW. This meant it was only operating at 56% of its maximum power, providing large room for improvement.

Optimizing your SAG mill operation - .Optimizing your SAG mill operation. Posted by Matrix on 21st March 2007 Sanjeev Latchireddi, Chief Process Engineer – Grinding Americas, Outokumpu Technology, looks at the shift from ball mills to SAG mills. Nowadays, the more successful plants are those that have adopted effective and efficient strategies to optimize their plant operation.

The project is the result of a partnership between Pueblo Viejo, the Barrick Digital team, and an outside supplier. The SAG mill at the site grinds the gold ore which is then sent to the autoclave for further processing.

How it Works: Crushers, Grinding Mills and .

Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebbles ...AMIT 135: Lesson 6 Grinding Circuit – Mining .SAG Mill Circuit Example – Gold Processing SAG mill circuit example for gold processing [image: ()] AG/SAG Mill.
