The ore drum dryer is the main equipment for dewatering various types of slag and ore powder. Through the principle of heat exchange, the ore can be quickly dried to the appropriate moisture, which facilitates the high-value reuse of its resources. So how does the ore tumble dryer operate?

Working principle of ore drum dryer

Ore drum dryers generally use a three-layer drum structure. After the wet slag enters the drying drum, it is divided into the following working areas: First, the guide area. The wet slag enters this area and contacts with high-temperature hot air to quickly evaporate the water. When the guide plate moves, 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 lifting plate to form a material curtain state. When the slag 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 slag adhered to the inner wall. In this process, the cleaning device also plays a role in breaking up the slag pellets, thus increasing the heat exchange area, which improves the drying rate; the third is the inclined lifting plate area. The wet slag has been in a low-moisture and loose state in this area, and the slag has no bonding phenomenon in this area. After sufficient heat exchange, the slag reaches the required moisture state. , enter the discharging area; the fourth is the discharging area, the drum does not have a lifting plate in this area, and the slag rolls and slides in this area to the discharge port to complete the entire drying process.
