They obtained pigments (from mill scale) under < mm, with a high surface area. In the case of corrosion product appearance, mill scale has a poor color, exposed hardness, and it is difficult to use as a pigment. Until now, this type of waste obtained from mill scale has not been reported as lowcost nanoadsorbent for waste decontamination.

The pelletization process takes place in the press channel of a pellet mill; this process has been the subject of several studies and modeling approaches (Holm et al. 2006, 2007, 2011; Larsson 2010; Nielsen et al. 2009b; Stelte et al. 2011b). During pelletization, biomass particles are fed into the mill.

Pellets will leave the pellet mill at temperatures as high as 80 to 90 degrees centigrade and moisture contents are high as 1718%. For proper storage and handling of the pellets, their moisture content must be reduced to 1012% and their temperature to about 5 degrees higher than the atmospheric temperature.

Pellet Mill. The series GC9PK pellet mill machines use the electric or diesel engines as the driving force for initiative axis, and operate cyclely. Major axis and disk mode are drived by gear wheels to produce the friction with the pressure roll bolt, the resulting friction temperature ( between pressure roller and the mode tray) can reach 80 ° C .

The increasing demand for biomass pellets requires the investigation of alternative raw materials for pelletization. In the present paper, the pelletization process of fescue, alfalfa, sorghum, triticale, miscanthus and willow is studied to determine if results obtained in a single pellet press (SPP) can be extrapolated to larger scale pellet mills.
