SAG Mill Diameter 40’x 26’ Long Copper Application

CHALLENGES FACED BY CLIENTS WITH CONVENTIONAL LINER:

1. Low Mill Availability: Frequent unplanned shutdown due to premature failure of conventional Liner (especially in shell discharge side), resulting in high maintenance cost and loss in productivity.
2. Low Wear Life - Around 100-120 days

RESULT TO CLIENT:

• Wear life increased to183 Days from 100-120 days of competitor lining (Wear Life increased by 50%-85%)
• Annual shutdown for replacement of liners changed to 2 from original 3. (One shutdown saving in a year)
• No Premature Liner Failure. (Mill Availability increased by 1%)
• Annual Production increase by 4.3%, which means the additional annual profit of approx. 14 Mn USD.
• Reduced opex: Specific energy consumption reduced by 4.1%, which means additional annual profit of approx. 880,000 USD.
• Annual reduction in carbon emission : 2680 Ton.

Milll Availability increased by 1%

BENEFITS TO CLIENT:

4.1% Lower SEC, 4.3% Higher Productivity, Lower carbon footprint

1. Average increase in TPH by Tega DynaPrime Liner: 141.48 t/h, equivalent to increase in the total production by 4.3 %.
2. Increase in 4.3% corresponds to extra ore processing of 1155 KT, equivalent to annual profit increase of 14 MUSD (Cu Grade 0.64%)
3. Average reduction in SEC by Tega DynaPrime Liner: 0.2486 kWh/t, equivalent to 4.1% lower specific energy consumption
4. Total 28 Mn Ton were treated annually, which means Tega DynaPrime resulted in total ann. energy saving of 6,960 MWh that corresponds to a profit of 880 KUSD
5. Savings of 6960 MWh/year means annual reduction in CO2 emission of 2,680 tons (EF: 0.385 Kg of CO2 eq/kWh)
