Grinding Circuit Modelling Documentation
This documentation describes the operating and underlying mathematics of the SAGMILLING.COM grinding circuit modelling program. It is intended to be used by the model users who want to operate and understand the functioning of grinding models.
Specific Energy Models
- Theory of power models
- Model types: specific energy consumption models
- Bond/Rowland Single stage ball milling
- Bond/Rowland rod mill & ball mill model
- Raw Bond/Barratt SAB & SABC model
- Optimized Bond/Barratt Models (including phantom cyclone allowance)
- Optimized Bond/Barratt model SABC (pebble crushing)
- Optimized Bond/Barratt model SAB (pebble recycle)
- Amelunxen SAG Grindability Index (SGI) SAB and SABC model (similar to SPI™)
- Morrell SMC SAG & ball mill model
- HPGR and ball mill (using Bond)
- HPGR and ball mill (using Morrell)
Mill power draw models
- Measurement of power (motor input versus shell, etc.)
- Media density for rods and balls
- Model types: mill power draw
- Austin SAG model (hybrid phenomenological and empirical model)
- Morrell C-model for SAG & ball mills (phenomenological model with empirical fitting. Sub-divided into a simplified model with 'typical' defaults and full model with all parameters editable)
- Loveday/Barratt SAG model (uses an internal table of empirical "Power Numbers")
- Nordberg ball mill model (largely empirical model)
- Nordberg rod mill model (largely empirical model)
- Crusher model (power allowance)
Laboratory testwork
- Testwork and test types
- Particle size does matter
Operating the Model
- General concepts
- Entering test results
- Creating a circuit model
- Creating/modifying a mill
- How to show a sub-set of results
- How to copy data out of a table and into a spreadsheet
- How to design a new circuit using grindability testing
Administrator functions
Benchmarking
Examples of how the SAGMILLING.COM model compare to published information for actual milling circuits.
- Category:Benchmarking
- Specific Energy Consumption Models
- SAG Mill Power Draw Models, use the IMPC 2016 paper
- Ball Mill Power Draw Models
Bibliography
- Bibliography: Specific energy consumption models
- Bibliography: Mill power draw models
- Bibliography: Testwork programs
