Iron ore handling, which may account for 20–50% of the total delivered cost of raw materials, covers the processes of transportation, storage, feeding, and washing of the ore en route to or during its various stages of treatment in the mill.. Since the physical state of iron ores in situ may range from friable, or even sandy materials, to monolithic As the main equipment in iron ore pelletizing plants, a damp mill is mainly used for the damp grinding of iron ore to provide materials for the pelletizing disc. It can deal with iron ore with a water content of 8-13%, not only increasing the surface area of the ore particles but also making the ore fully mixed and ground to shorten the wholeDamp Mill Ball Grinding Machine Iron Ore Pelletizing Equipment

Pelletization an overview ScienceDirect Topics
The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization: .Iron ore sintering is a promising thermal method for co-disposing the municipal solid waste incineration (MSWI) fly ash. To reduce the increased dioxins in flue gas caused by adding fly ash powder, pelletizing was used as a pre-treatment for fly ash to enhance the degradation of dioxins.Improvement on the thermal cracking performance of pellets prepared
