G index coal
The general “freshness” or weathering index of the samples was also differences were observed between the H/C ratios, except for coal G#5 which had a The Caking Index, G, has been widely popularized and applied in coal geological exploration, production and utilization departments in China. This index was established after improving the Roga Index, an international method used for determining the caking power of bituminous coal. G CAKING INDEX TEST This test was developed in China and is performed in accordance with GB/T 5447 and ISO 15585 standards. It is used as a primary met coal evaluation tool by Chinese coke producers. In this test, 1g of minus 0.2mm coal is mixed with 5g anthracite and placed in a crucible. A 100-115g steel weight is placed on top of Hardgrove 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. 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. According to GB5447–85, a closely compacted mixture of 1 g of test coal (< 0.2 mm) and 5 g of standard anthracite is carbonised for 15 min at 850°C in a covered porcelain crucible. The residue obtained ( M ) is then subjected to a series of two drum tests, each at 50 rpm for 5 min. the coal caking ability to combine inertinite matter, including Roga Index (G. I.). Regarding parameter FSI, maximum fluidity, maximum dilation are preferred in North America, while caking index, maximum plastic layer thickness, and maximum dilation are normally used in the Chinese system.

FACTOR BOX AND FaCS METHODOLOGY MSCI FaCS is a standard method (MSCI FaCS Methodology) for evaluating and reporting the Factor characteristics of equity portfolios. MSCI FaCS consists of Factor Groups (e.g. Value, Size, Momentum, Quality, Yield, and Volatility) that have been It is distinguished by the strong low-density coke produced when the coal is heated in a low oxygen (O2) environment or in absence of air to reduce mineral impurities (e.g. less sulphur, phosphorus). On heating, the coal softens, and volatile components evaporate and escape through pores in the mass. COALspot.com keeps you connected across the coal world.
