Energy Curve Enhancement Blog 8: Including pumping …

Based on experience and the energy curve database, a typical primary crusher and the SAG mill can be assumed to be 1 km apart, consuming about 0.40 kWh/t in conveying power. Another 500 m of conveying can be assumed to be required for the pebble recycle, but since the flowrate is only about 10% of the feed, the contribution of the pebble recycle may be as low as 0.02 kWh/t.

Energy Use of Fine Grinding in Mineral Processing | …

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and ...

Grind Calibration Curve -Laboratory Test

Before doing multiple laboratory flotation bench tests in which you need P80 grind controlled or predicted, you need to build a Grind Calibration curve following this short procedure. You will consistently add sufficient water to the mill to achieve a pulp density of 67% solids (Example: 1 kg solids + 0.5 kg water or 2 kg solids + 1 kg water.) You may need to add more water yet depending on ...
