2015-06-12: Test result summary

A testwork summary listing now shows the Mia and Mib values needed for the Morrell SMC model. The DWI value was removed from the summary as it is not used directly in any of the models.

Minor changes to the PDF report showing specific energy model names rather than their ID number.

2015-06-02: Tent Diagram

• A Tent diagram can now show just power, just torque, or overlay both.

2015-05-13: Drive torque

• Modified the tent diagram to show the process torque demand (at the mill shell) across the range of mill speed
• Added the torque (at the mill shell) to the list of properties in the mill detail listing.

2015-05-07: Tent diagram

• Modified range of tent diagram up to 85% of critical speed.
• Fixed bug where operating speed determined the torque of the tent diagram peak.

2015-04-25: Added Morrell SMC (Mia, Mib) SAB & SABC circuit model

• New specific energy model for SAG & ball mill circuits that uses Mia (from SMC™ test) and Mib (from a Bond Wi_BM) values.
• Must enter the following information for the Bond ball mill work index to permit Mib calculation in order to run this model:
  • Test P100 (closing screen) size, µm
  • Test P80 size, µm
  • Test F80 size, µm
  • Test grams per revolution (GPR)

2015-04-21: Added rod mill-ball mill circuit model

• New specific energy model using Bond/Rowland method for rod mills and ball mills.
• Fixed a problem with default values not appearing in drop-down select fields.
• Tweaked behaviour of SGI model under SAG-limited and ball-limited conditions.

2015-04-10: Added Amelunxen SGI model

• New specific energy model for SAG & ball mill circuits that uses SGI (or SPI™) values instead of Bond work index for rod mill and crushing.
• Mandatory to set the CFsag and CFball configuration factors, see the documentation.

Bug list

Known bugs that are scheduled for fixing:

• SGI model PDF output does not show the CFsag and CFball values [mostly cosmetic, low priority]
