ActiveDetermination of grindability index of coal―Hardgrove method
煤的可磨性指数测定方法 哈德格罗夫法
Application Summary AI generated
This standard specifies the method for determining the Hardgrove Grindability Index (HGI) of coal, which measures the relative ease of pulverizing coal. It is applied in the coal mining, power generation, and coke production industries to evaluate coal quality for mill design, grinding efficiency, and fuel preparation processes. The test is conducted under controlled laboratory conditions using a standardized Hardgrove machine to ensure consistent and comparable results across different coal samples.
