Pellet feed material generally results from fine grinding to achieve a liberation size roughly between 20 μm and 150 μm. Following this, beneficiation is applied to generate concentrate grades of 65–69% Fe, by gravity separation, magnetic separation or flotation, or combinations thereof. One of the effects of the beneficiation generally is ...
Keywords Pelletizing .Agglomeration .HPGR .Milling 1 Introduction Modern iron ore pelletizing process operations may be divid-ed into two main process sections: feedstock preparation and agglomeration processes. In most plants, the required particle size distribution (PSD) is obtained through the wet ball mill circuit.
mixing process. Weighted quantities of each ingredient (either as a batch or continuously) are thoroughly mixed (either in a batch mixer of a continuous flow mixing unit) and then conveyed to a bin above the pellet mill. Some manufacturers have installed systems to grind all of their premixed materials prior to entering the pellet mill.
Chemplex ® grinding and pelletizing additives are formulated to aid in the grinding and pelletizing process by reducing particles to a uniform size and distribution forming a homogeneous sample blend for XRF analysis.
