What is ISO 10753- Assessment of the liability to breakdown in water of materials associated with coal seams about?
ISO 10753 specifies a method for assessing the liability of materials associated with coal seams to breakdown on agitation with water.
The liability of the shale to breakdown is measured by the proportion of the degraded material passing through a test sieve having a nominal size of openings of 500 μm.
Who is ISO 10753- Assessment of the liability to breakdown in water of materials associated with coal seams for?
ISO 10753 on - Assessment of the liability to breakdown in water of materials associated with coal seams applies to:
- Coal preparation plant
- Testing agencies
- Manufacturers of coal seams
Why should you use ISO 10753- Assessment of the liability to breakdown in water of materials associated with coal seams?
ISO 10753 provides you guidance on conducting the simplified sedimentation test for enabling you to measure extent of breakdown of materials associated with coal seams.
The method described in ISO 10753 also enables the liability of the shale to form slimes to be assessed, by determining the proportion that is below a nominal particle size of 10 μm.
The test can be adapted to assess the relative tendencies of shales to break down in a particular plant, by using the same water as is used in that plant.
The test result provides you with the useful information on the character of the breakdown from the relationship between the proportion of degraded material passing a 500 μm test sieve and the proportion of slimes.
