21/30404487 DC

This standard 21/30404487 DC BS ISO 923. Coal. Density separation equipment for coal. Performance evaluation is classified in these ICS categories:

• 73.120 Equipment for processing of minerals
• 73.040 Coals

This International Standard describes the principles and methods for evaluating the performance of density separation equipment used for coal cleaning operations. Testing and sampling procedures are specified, and methods of presenting test results are detailed. Performance parameters are recommended and defined, and their determination is formulated, thereby permitting their use in evaluating, comparing and predicting performance levels of coal cleaning operations.

This International Standard is applicable to the following types of coal cleaning equipment using relative density as the main characteristic for separation:

1. dense-medium separators;

2. jigs;

3. other density-based separators, including spirals, teetered beds, reflux classifiers, tables, water-only cyclones, etc.
