The most widely used parameter to 1) measure ore grindability is the Bond work index (Wi). This measures the resistance of materials to breakage. The Bond standard grindability test has been described in detail by Deister (1987) and Levin (1989) who proposed method to determine the grindability of fine materials (Wills, 2006). ... 4750, and the ...

Hardgrove Grindability Index is a measure of how easy raw coal can be milled. Coals with low HGI require more energy to pulverise and tend to produce coarser particles, which take longer to burn out in the boiler. High moisture coals require higher air inlet temperatures for drying. Combustion stability. Coal combustion is a two-stage process.

ECONOMIC FEASIBILITY AND TECHNICAL CONSIDERATIONS OF OIL-TO-COAL CONVERSIONS by D. F. DUNPHY, Manager Plant Improvement Engineering Department
To determine the rank of coal, laboratory tests such as proximate analysis (moisture, volatile matter, fixed carbon and ash), ultimate analysis (elemental composition of organic fraction on weight percent basis; carbon, hydrogen, oxygen, nitrogen and sulfur), heating value, hard groove grindability index (HGI) and petrographic analysis were carried out.
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured. The grindability is useful in evaluating power requirements for grinding.
Bond's work index one of the most acceptable approach to calculate the grindability index. Who is Reginald Clinker? he was a inventor. ... How to find magnesia in clinker .
A PCI product's Hardgrove Grindability Index (HGI) and its ash fusion temperature are two other parameters on which it is judged. The use of PCI goes beyond serving as a replacement for coke to ensure cost-efficient hot iron production.
To get this measure, the coke must be tested for moisture content (see same). ... Hargrove Grindability Index (HGI) ... understood, the coke from some crudes forms into small, tight, non attached clusters that look like pellets, marbles or BB's. Get Price
