Advanced Coal Science Coal – How It Is Formed. Coal is made from Peat that has been compressed and then subjected to high temperature ( + 100° Celcius) for a few million years to drive off moisture, methane and carbon dioxide bearing molecules.
specification of grindability by Hardgrove are applied more frequently. Hardgrove grindability index (HGI) is determining factor of energy consumption during grinding. The HGI value is used for more detailed coal specification and is significant also for the design of capacity of particularization equipment and grinding circuits.
Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic luster.It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92% ...

May 01, 2013· The Hard grove method ismostly used to determine the grindability ofcoal, but also in determining grindability ofother raw materials. Bond's method is used toevaluate the rock grindability. 4. HARDGROVEGRINDABILITY INDEX (HGI)• The Hardgrove Grindability index is designed todetermine the ease with which coal can bepulverized.•
3.1 This test method develops a measurement of grinding or pulverizing characteristics that can be used to evaluate the yield, or energy input, or both, required in a grinding or pulverizing process, which can impact a wide variety of processes, including combustion, coke-making, liquefaction, and gasification.
Anthracite coal, mined from the planet's oldest geological formations, has spent the longest time underground. The coal has been subjected to the most pressure and heat, making it the most compressed and hardest coal available. Hard coal contains greater potential to produce heat energy than softer, geologically "newer" coal.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
