Minerals discharged from rotary dryers are usually too hot for magnetic separation or bagging in plastic bags.
Indirect coolers are used when the dry product outlet temperature must be lower than the ambient temperature plus 15°C.
Water-Cooled Indirect Cooler for Granular Materials
- This water-cooled cooler is designed to cool minerals from 80°/90°C at dryer outlet down to 30°/35°C depending requirements.
- Dried product can then be weighed and bagged directly after the dryer.
- Cold enough for bagging in plastic bags or as feed to magnetic separation equipment.
- Cooling water requirement typically - 1000 Litres per ton of dried product.
