Abstract

fetched live from OpenAlex

With increased budget constraints, innovative cost reduction methods are required to increase the profitability of today's mines. Abrasive wear reduction is a novel way to reduce costs and increase productivity. Specifically, gouging abrasion is making an increased contribution to abrasive wear losses in the oil sands industry. To assess material property requirements for mitigating this wear mechanism, jaw crusher gouging abrasion tests using a modified ASTM G81 procedure, have been carried out on a range of wear materials of interest for oil sands mining service. The method involves a comparison of the wear losses that occur for reference and selected test plates when a controlled amount of standard feed rock is comminuted in a laboratory jaw crusher. Among the classes of material evaluated have been Q&T plate steels, austenitic manganese steel, chromium and chromium molybdenum white irons as plain castings and in laminated forms and also chromium carbide and tungsten carbide overlaid wear plates. In addition, the initial stages of relationships are presented relating wear rates/factor, determined from the laboratory gouging abrasion test, to the quartz content of the abrasive material. Of all the materials tested, the laminated CrMo white consistently had the lowest wear factor (best gouging abrasion resistance). From the data produced by this work, the wear factor has a linear relationship with quartz, while the wear rate has a non-linear relationship.

Not 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.
