The drying of iron ore concentrate is crucial in mineral processing, which directly affects product quality and energy consumption in subsequent processing. The drying process can remove moisture from iron ore concentrates, improve product quality, improve physical performance, improve transportation and storage conditions, and reduce energy consumption, thereby improving overall economic and environmental benefits.

  Iron ore concentrate is the product of iron ore purified by ore ore. The original ore is crushed, grinded, sorted and other steps to finally obtain high-grade iron concentrate. The drying process in the iron ore processing process is usually located in the iron concentrate dehydration stage after ore dressing, before transportation, storage and smelting. After drying, iron concentrate can effectively reduce moisture, reduce the cost of subsequent treatment, and improve smelting efficiency.

  Iron ore dryer is a drying equipment specially developed and manufactured for iron ore drying based on the rotary dryer and combined with the characteristics of iron ore. The iron ore dried has high quality, wide application scope and large market demand, which can bring certain economic benefits to enterprises.

  Working principle: The iron ore is sent into the dryer through a feeding device such as a vibrating feeder. The iron ore materials are continuously picked up and scattered under the inner layer and scattered in a spiral manner to achieve heat exchange. When the iron ore reaches the other end of the inner layer, it then enters the middle layer for counter-current drying. The iron ore is moving in the middle layer in a two-step backward step. The material in the middle layer fully absorbs the heat emitted by the inner layer drum and the heat of the middle layer drum, and reaches a better dry state here. Iron ore travels to the other end of the middle layer and falls into the outer layer. The material travels in a rectangular multi-circuit manner in the outer layer drum. The material that achieves the drying effect quickly travels out of the drum under the action of hot air. Wet material that does not achieve the drying effect cannot travel quickly due to its own weight. It is fully dried in this rectangular plate.
