Plant 2 feed was the product of wet rod mill-ball mill grinding circuit with F80 of about 20 mm. The energy consumption was 25.5 kWh/ton for this application. As given in Table 3, the HPGR circuit consumed 8 kWh/ton. These results, at least, showed that HPGR is a promising alternative for mineral processing applications.

In March 2007, Imperial commissioned Tetra Tech to develop a scoping study into the use of High Pressure Grinding Rolls (HPGR) in the comminution circuit to reduce the feed size produced by the tertiary crushers, in order that the existing rod mills could be converted to ball mills, thus achieving the 30,000-tons-per-day production.

Sizers. A third ball mill has been installed along with two additional Stack Sizers to increase production to 3700 t/d. The third ball mill will operate in closed circuit with four Stack Sizers as a secondary grinding circuit to feed the flotation plant. CASE STUDY 205

Several gravity options were reviewed for the secondary (ball mill), tertiary and regrind grinding circuits. Due to the coarse nature of the native copper and the feed size to the gravity circuit required in the ball mill circuit (up to 10mm), there were only 2 gravity options reviewed for this circuit. The first was Dense Media

case study of ball mill grinding copper iran - Mining. HD Technologies Case Study SPM Instrument. The working principle of the ball mill is as follows In a continuously operating ball mill the feed material copper ore passes through the central hole of one of the caps into the drum where it is exposed to the grinding media The grinding of the material occurs during impact …

There have been different studies on the influences of parameters associated with grinding balls such as ball size distribution and ball shape on the particle comminution [20–22]. There are different types of ball mills for obtaining powder, stand out horizontal ball mill (low-energy) and the high efficiency (high-energy) ball mill.

The Cayeli concentrator was commissioned in 1994, with a design capacity of 600 000 tonnes/year. The grinding circuit was a classical rod mill/ball mill combination. The rod mill was converted to a primary ball mill in May 1997. The reasons for conversion were to use mill power more efficiently and eliminate feed interruptions during rod charging.
