Iron ore fines drying matters for pellet plants that grind ore dry and for exporters shipping fines that can liquefy at sea when moisture is too high. The material is heavy, abrasive and often blended with clay or goethite, so dryers are built for high tonnage and robust feed handling.
To dry iron ore fines, GEM recommends the Rotary Dryer. Typical moisture is 8–14% in the feed and 1–6% after drying. Rotary Cascade Dryer and Flash Dryer are used when the feed or site calls for it. Every project starts with a pilot trial on your own sample.
A direct rotary dryer handles large tonnages of heavy, variable iron ore fines and tolerates clay content. A cascade dryer offers a smaller footprint for granular feed at high temperature, while a flash dryer combined with a mill suits dry grinding of concentrate for pellet feed.
| Typical feed moisture | 8–14% |
| Typical target moisture | 1–6% |
| Recommended dryer | Rotary Dryer |
| Alternatives | Rotary Cascade Dryer, Flash Dryer |
| Application area | Minerals, Ores & Ceramics |
| Industries | Minerals, Mining & Ceramics |
Drying below the transportable moisture limit keeps cargoes shippable and avoids rejected loads. For pellet plants, dry ore lowers grinding energy and stabilises green ball quality.
Plants searching for a iron ore fines dryer or comparing a iron ore drying plant usually need three answers: which dryer fits, what it costs to run, and how fast it pays back. For Iron Ore Fines, we start from your throughput, current moisture (typically 8–14%) and the target (1–6%), trial a sample on the Rotary Dryer, and return a sized recommendation with a budget quotation for your minerals operation.
We trial your material in our pilot facility before any equipment decision, then size the dryer from real data.
Describe it in the form, or message an engineer directly.
