Performance of spiral classifier

Performance of spiral classifier

Sep 23, 2019 The spiral classifier is one of the important mineral processing equipment, whose working principle is to classify the materials by using the difference in the settling speed of solid particles in the liquid. The classifying effect of the spiral classifier will directly affect the content of the qualified product in the returned sand, thus affecting the grinding efficiency of the grinding mill

  • Spiral Classifier Spiral Classifier

    Product introduction:Spiral classifier is commonly used in the grinding circuit of the beneficiation as the pre-classification and inspect classification machine and also in the ore washing and desliming operation.It is forms a closed cycle easily with the grinding machines with advantages of simple structure, reliable work and easy operation

  • Spiral classifier or hydrocyclone - Grinding Spiral classifier or hydrocyclone - Grinding

    A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & Exploration Mineral

  • Performance Metrics for Classification problems in Performance Metrics for Classification problems in

    Nov 11, 2017 We can use classification performance metrics such as Log-Loss, Accuracy, AUC(Area under Curve) etc. Another example of metric for evaluation of machine learning algorithms is

  • Python Decision Tree Classification with Scikit-Learn Python Decision Tree Classification with Scikit-Learn

    Dec 28, 2018 In Scikit-learn, optimization of decision tree classifier performed by only pre-pruning. Maximum depth of the tree can be used as a control variable for pre-pruning. In the following the example, you can plot a decision tree on the same data with max_depth=3. Other than pre-pruning parameters, You can also try other attribute selection measure

  • Association of Malignancy Prevalence With Test Properties Association of Malignancy Prevalence With Test Properties

    Importance: It is crucial for clinicians to know the malignancy prevalence within each indeterminate cytologic category to estimate the performance of the gene expression classifier (GEC). Objective: To examine the variability in the performance of the GEC. Design, setting, and participants: This retrospective cohort study of patients with Bethesda category III and IV thyroid nodules used

    All classifiers were run on each dataset in a 100-repeated nested fivefold cross-validation with hyperparameter tuning. Performance metrics (AUC, calibration slope and intercept, accuracy, Cohen's kappa, and Brier score) were computed. We ranked classifiers by AUC to determine which classifier is likely to also perform well in future studies
