size reduction in iron

Ultrasmall iron nanoparticles Effect of size reduction on

Stable iron nanoparticles have been synthesised by the decomposition of {Fe(N[Si(CH3)3]2)2}2 under dihydrogen pressure. Those conditions lead to a system of monodisperse and metallic nanoparticles which diameter is less than 2nm and stabilized by HN[Si(CH3)3]2. The magnetization is found to be MS=1.92Bat., i.e., 10% lower than the bulk value.

Iron processing Britannica

As mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size.

Process engineering Particle size reduction techniques

Size reducing equipment relies on compression or impact. Compression is applied via moving jaws, rolls or a gyratory cone. The maximum discharge size is set by the clearance, which is adjustable. Impact based equipment commonly uses hammers or media. The pros and cons of several types of size reduction equipment are shown in the table.
