Our heavy-duty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.
Ore Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or cyanidation.Practice varies, depending upon the type of ore and the amount of reduction required. In addition, some of the older properties continue with methods that perhaps are not considered the best in light of recent improvements but that cannot be ...
Iron ore fines are characterized on a physical basis by variations in particle size, shape, density, porosity, surface area, roughness, and wettability. Furui et al. (1977) divided iron ore particles into nucleus particles of + 0.7 mm size, intermediate particles of − 0.7 + 0.2 mm size, and adhering particles of − 0.2 mm size.

In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.
Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
