Industrial ore dryers are also called tumble dryers. Industrial ore dryers are widely used in building materials, metallurgy, chemicals, cement and other industries. Iron ore dryer equipment is suitable for slag, limestone, coal powder, slag, clay, boron magnesium ore, phosphate ore, manganese ore, high manganese ore, Nickel ore and other materials are dried.

The iron ore drum dryer mainly consists of a hot blast stove (multi-heat source burner), feeding conveyor, drum dryer, discharging conveyor, induced draft fan, cyclone dust collector, bag dust collector (or wet dust collector) and operation control system.

The working principle of this set of equipment is as follows: After the wet iron ore enters the drying drum, it is divided into the following working areas: First, the guide area. The wet iron ore enters this area and contacts the high-temperature hot air to quickly evaporate the water. The iron ore is guided at a large guide angle. When the plate is moved, if no bond is formed, it will be directed to the next work area; the second is the lifting and cleaning area, where the wet material is lifted up by the plate to form a material curtain state. When the iron ore falls, it is easy to form a bonding roller wall phenomenon. In this area, because the equipment is designed with a cleaning device, the cleaning device effectively cleans the iron ore adhered to the inner wall. In this process, the cleaning device also plays a role in breaking up the iron ore pellets, thereby increasing the heat exchange area, which improves the drying rate; the third is the inclined lifting plate area. The wet iron ore in this area has been in a low-moisture and loose state. The iron ore no longer has a bonding phenomenon in this area. After sufficient heat exchange, the slag reaches the required The moisture state enters the discharging area; the fourth is the discharging area. The drum does not have a copy plate in this area, and the iron ore rolls and slides in this area to the discharge port to complete the entire drying process.
