2.5.7 Coal Grindability Test (HGI) The Hardgrove Grindability Index (HGI) is a measure of ease for coal pulverisation. The coal in pulverised form is used for firing boilers and furnaces. A 50 g sample of coal, which has been prepared (1.18 mm), is kept in a grinding mill having eight steel balls running in circular path as grinding media.

Having developed the sharpness parameter, De Pellegrin et al.

6. Malleable iron is a ductile form of cast iron that is produced by heat-treating white iron. 7. The principal difference between malleable and gray iron is ductility. Malleable iron is significantly more ductile because the temper carbon nodules do not present a continuous fracture path like that presented by the graphite in gray iron.

These three laws may all be derived from the basic differential equation: (5.2) d E d L = − CL p which states that the energy d E required to effect a small change d L in the size of unit mass of material is a simple power function of the size. If p = − 2, then integration gives: E = C 1 L 2 − 1 L 1

The Iron Age, which can be dated as beginning around 1200 B.C., followed the beginning of the Bronze Age by some 1300 years. The reason for the delay was the absence of methods for achieving the high temperatures needed to melt and to refine iron ore. Most metalworking was done by hand until the 13th century.

The rare earths share many common properties this makes them difficult to separate or even distinguish from each other. There are very small differences in solubility and complex formation between the rare earths. The rare earth metals naturally occur together in minerals. Rare earths are found with non metals, usually in the 3+ oxidation state.
