How it works and what it targets
One coarse/fine separation provides a main cut point. A narrow fraction may require coarse removal followed by fine removal, or a different sequence based on the feed distribution. Each stage changes the next stage's concentration and size distribution. Stage count should follow mass balance and recycle load, rather than simply the number of products.
Reference process steps
- 1Define upper/lower limits and permitted distribution tails.
- 2Arrange coarse removal, fine removal and any required redispersion.
- 3Meter and test every outlet before assigning recycle or by-product destinations.
Configuration and operating conditions
Abrasives and polishing powders
Diamond and silicon-carbide abrasives emphasize narrow fractions and oversize limits. Ceria polishing powders may require coarse or fine removal. Acceptance criteria and settings must follow each downstream application.
Multiple products and recycle
Multiple product grades require separate storage, transfer and mix-up prevention. When coarse material returns to a mill, include the recycle in mill-capacity and system-energy calculations.
Information needed for selection
Submit each product's size window, expected mass fraction, feed variability, cross-fraction limits, conveying arrangements and available space.
Discuss selection inputsTrial and acceptance considerations
Validate the scheme with a full mass balance and size report for every stream. Select stages, arrangement and models from trials; historical category names do not define a configuration.
