Crushing properties of coal . There is a close relation between HGI and the coal quality, aswell as the power consumed in grinding. Accordingly, the HGI values of coal samples Coal Structure and properties of coal Britannica,An important property of coal is its reflectivity (or reflectance )—i.e., its ability to reflect light. Reflectivity is measured by shining a beam of monochromatic light (with a wavelength of 546 nanometres) on a polished surface of the vitrinite macerals in a coal sample and measuring the percentage of the light reflected with a photometer.Crushing Properties of Coal 2. Binary Coal Blends,The Hardgrove grindability index HGI is closely related to the power consumed in crushing coal and may be used to optimize crushing in the coalpreparation shops at coke plants, as shown in [1–7].The factors affecting HGI for Ukrainian and imported coal were studied in .The results showed that HGI depends on the carbon content and

Study on the variation law of geometric and surface

The variation of particle properties and surface physicochemical properties during coal crushing was studied. The geometric properties of coal particles were explored by analyzing the particleResearch on Energy Dissipation Laws of Coal Crushing ,Dynamic crushing characteristics of coals are closely related with energy absorption and release of coals under certain strain rate. Hence, it is necessary to investigate energy dissipation laws of coal crushing under the impact loads with different strain rates.
