Grinding mechanism by cascading
In coarse to medium grinding, the particle size reduction is mainly made inside the ball charge. Trajectories must allow the material to enter the ball charge made of grinding media big enough to reduce it.
The design will depend on:
- Drilling pattern on mill shell
- Mill speed (rpm)
- Maximum grinding media diameter (mm)
- Grinding media filling degree (%)
Key benefits:
- Optimum compromise between lifetime and grinding efficiency
- Continuous optimization of the liner profile via wear profile studies
- Ease of installation process (filler ring and handling system)
- Anti-pulp racing design to avoid pulp circulation
- Design to minimize the number of plate/liner models
- Design to minimize grinding media consumption
