Modified Bond and Rittinger energy-size models for the laboratory IsaMill
Bibliographic record
Abstract
The IsaMill is a horizontal high speed stirred mill developed by the Mount Isa Mines and Netzsch-Feinmahltechnik GmbH in the late 1990's to improve the performance of ultrafine grinding for mining industry. The IsaMills are now widely applied all over the world. This paper discusses the interpretation of the IsaMill laboratory test results for assessing material grindability and for industrial scale-up. Previously it was found that the Bond and Rittinger energy-size models do not reproduce the experimental results as well as the "signature plot". However, the modified Bond and Rittinger energy-size models using a variable grindability coefficient offer better accuracy. This, along with the extended functionality for grinding media size assessment, indicates a potential to improve the process for selection the industrial scale IsaMill circuits from the laboratory-scale tests.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
