The Hardgrove Grindability Index HGI is a measure of coal’s resistance to crushing Grinding studies and the resulting HGI allow many different types of coal users to evaluate how coals will perform in their mills allowing them to estimate grinding power requirements and throughput capacities
Hardgrove Grindability Index analysis is the ASTM method of determining the hardness of coal when pulverized for steam generation or size reduction Grindabilities typically range on coal from 35 – 110 Harder and less grindable coal rates a smaller HGI index number
Other index known as Hardgrove Index is also used to scale grindability of materials particularly coal Hardgrove index is commonly used to determine power requirements of vertical coal mills Relation between BWI and Hardgrove Index can be described by the following equation BWI 435HGI 091 GRINDING MILLS
Jan 01 2013 · As of 2009 world cement output was estimated at 304 billion tonnes metric tons 6 China represents 561 of the world’s output while the USA represents 20 7 Fuel used by the US cement industry is 60 coal 13 petroleum coke and 3 natural gas 8 According to the US Energy Information Administration EIA the manufacture of cement
11 This test method covers the determination of the hardgrove grindability index HGI of those petroleum cokes that contain no dedusting additive The procedure for this test method is the same as in Test Method ns of this test method contain the significance and use of the HGI of petroleum coke preliminary sample preparation procedures and procedure and precision and bias data
Coal fineness has a direct relationship with its reactivity Hence in the cement plant a special significance has been given to the milling behavior of coal It has been observed that low volatile matter in coal can be co mpensated by finer grinding It is also desirable that coal must have a high Hardgrove Grindability Index
May 01 2013 · Hardgrove grindability index HGI • It can be used by industry to determine powerconsumption during the grinding process• • combustion in a boiler to generate power• pulverized coal injection in a cement kiln tomake cement clinker• pulverized coal injection in a blast furnaceto assist economic iron making• entrained
Large amounts of energy are required to produce cement It takes about 200 kg of coal to produce one tonne of cement and about 300400 kg of cement is needed to produce one cubic metre of concrete Coal combustion products CCPs such as Fly Ash also play an important role in cement manufacture and in the construction industry generally
Jan 10 2008 · Energy Source for Cement Kilns KIS KISPL meets coal quality specification for Cement Production JANUARY 10 2008 NEW DELHI The two basic processes in cement production are the wet and dry processes which are named after the manner in which the raw mix is introduced into the kiln In the wet process the mix is introduced into the kiln as a slurry with 2040 moisture
