An apparatus and method for removing an underflow stream
Bibliographic record
Abstract
This invention relates to an apparatus and method for removing an underflow stream and in particular to an apparatus and method for removing an underflow stream from a separator. The invention has been developed primarily for use with a mineral particle separator. One aspect of the invention provides an apparatus for removing an underflow stream from a separator, said separator having a discharge outlet for discharging said underflow stream, said apparatus comprising: a source of pressurised fluid; a first conduit for fluidly connecting said pressurised fluid source to said discharge outlet such that said pressurised fluid is directed to impede the flow of said underflow stream in said first conduit, thereby creating a fluidisation zone, and a second conduit fluidly connected to said first conduit so that material from said fluidisation zone flows into said second conduit for removal from said apparatus.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
