Grinding of iron ore pellet feed concentrate (HPGR, closed circuit with partial load recycle)
|Customer:||Liuzhou Steel Group|
|Scope of Work:||Supply HPGR and System Solutions for Iron Pelletization Plant|
- HPGR (CLM150140, with roll 1500mm diameter, 1400mm width. Power is 2x1000kW with throughput 600~800t/h)
- Closed circuit with edge recycle. Moisture at 8-9%
- Feed material: 200 mesh, 80%
- Output material specific surface area increase : 200-400 cm2/g
- Year of installation: 2021
- HPGR main purpose in pellet feed applications is a combination of fines generation with a main emphasis of creating a high specific surface area increase.
- HPGR before the ball mill or completely replace the ball mill is shown to improve the pelletization. (Less energy consumption, higher BSA, reducing the usage of bentonite, less noise pollution etc).
