Get PriceHardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill.
Get PriceA lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction can take place at anywhere above 840°C (1544°F), but is generally considered to occur at 900°C(1655°F) (at which temperature the partial pressure of CO 2 is 1

Get PricePet coke is being used to co-fire lime regeneration kilns in pulp and paper mills. Mills can replace 85% to 90% of the oil or natural gas used to fire them. Pet coke's emissions characteristics are similar to Those of coal. The capital cost of a complete system typically can be recouped in 2 to 3 years.

Get PriceHardgrove Grindability Index Of Petcoke. The hardgrove grindability index (hgi) is a measure of coals 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.
Get PriceHardgrove 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.

Get PriceThe chemical composition of slag 1,7 can vary over a wide range depending on the nature of the ore, the composition of the limestone flux, the coke consumption and the kind of iron being made. It can also change over the years with alterations in the sources and types of ore being smelted. These variations affect the relative content of the four major constituents: lime, silica, alumina and
