Calcination Limonite Rotary Kiln Process

Rotary kiln is one of the important host equipment for limonite, and limonite is one of the main iron minerals, it is based on iron oxide as the main component of the brown natural multi-mineral mixture. But its iron content is not high, is the secondary iron ore.
Limonite rotary kiln dryer, according to the material and hot gas flow direction is different, there are two kinds of downstream and countercurrent. In the choice of rotary kiln dryer counter-current operation, should be based on the characteristics of the material, particle size, the final moisture requirements of the material and the layout of the workshop and other comprehensive consideration. Based on the rotary kiln equipment on the material requirements are extremely strict, our ZK corp has a professional selection of limonite project tailor-made for your limonite rotary kiln process, but in the cement plant, two operation methods are used, while downstream operation occupies the majority.

Our company's common limonite rotary kiln process is: First, the ore from the reservoir by the electronic belt scale, belt conveyor, steady silo, lock the wind pump directly into the rotary kiln tail, kiln tail only set silos to reduce investment. Second, the ore into the rotary kiln is first heated, the ore in the kiln and the hot air reverse movement, in the heating zone ore is heated to the reduction temperature into the reduction area. Finally, into the cooling zone, meet with the incoming gas, the gas is preheated, the ore is cooled and discharged outside the rotary kiln, after the continuous bucket conveyor water cooling, into the reservoir to be selected.

ZK Corp production of limonite rotary kiln calcination equipment with advanced structure, low pressure loss of the vertical preheater can effectively improve the preheating effect; the device has a reliable scaly seal at both ends of the combination. So that the air leakage coefficient of less than 10% of the usage of composite refractories to reduce the loss of radiant heat; filling, can be divided into a circular or square vertical cooler, reducing the moving parts and rotary kiln with special materials.
