eng.ball-mill-Bond-work-index Calculator
Calculates the energy required to grind ore from a feed size to a product size using Bond's work index equation. Bond's Work Index (Wi) ranges from 5 kWh/t for soft limestone to 60 kWh/t for hard quartzite — it's the primary ore grindability test in mineral processing.
Inputs
Wi Kwh T
Energy transferred by a force over a displacement (J = N·m).
F80 Micron
Reference formula or conversion factor shown for context.
P80 Micron
Reference formula or conversion factor shown for context.
Results
specific energy E (kWh/t)
Sample size or count used in the calculation.
reduction ratio F80/P80
The proportional relationship between two quantities.
E = Wi·(10/√P80 − 10/√F80)
Reference formula or conversion factor shown for context.
Wi classification
Category assigned based on where the computed value falls on a defined scale. Check which standard or guideline defines these boundaries.
throughput at 1 MW mill (t/hr)
Amount of work completed per unit time — requests per second, MB/s, or transactions per second.
work index source
A normalised score comparing the result to a reference baseline.
