It is suitable to choose the pulverized coal with close grindability index when adopting mixing injection. 采用混合煤喷吹时,宜选用可磨性指数相近的媒。
The grindability of coal is an important parameter in pulverized coal utilization, and the HGI ( Hardgrove Grindability Index) is relevant to the coal pulverization and the particle size distribution. 可磨性是煤加工利用过程中的一个重要指标,可磨性指数与煤的破碎机理、煤粒破碎后的粒度分布均有关系。
The correlation between proximate analysis of coal and hardgrove grindability index ( HGI) was studied in this paper. 采用多元统计方法对煤质特性与可磨性HGI的相关性进行了研究。
The grindability of ball milling of phosphate ore bearing rare earths was determined by using a simplified test method of determing approximate work index. The work index of the ore was about 16.16kWh/t. 采用测定近似功指数的简化试验方法,对贵州织金新华磷块岩矿床下矿层含稀土磷矿石的球磨可磨性进行了测定,得到该矿石的功指数约为16.16kWh/t。

The analysis indicates that the most important coal quality factor, that effects the pulverizing system's operational safety, the mill's output and its operational economy is the coal's grindability index. 分析表明:对制粉系统运行安全性、磨煤出力和经济性影响最大的煤质因素是可磨性指数和原煤水分。
The results show that the carbon content, the moisture content by air drying, the grindability index, and the surface area by Mercury Porosimeter are the main factors influencing the slurryability of CWS. 结果表明,与煤成浆性有关的主要煤质因素为煤的碳质量分数、空气平衡水分、可磨性指数以及压汞仪所测煤的比表面积,复相关系数达0.988;
The mill dynamic model was established and its online modification for fuel command gain and inertia was performed with coal-fired calorific value and grindability index. 建立了制粉动态模型,并利用燃煤发热量和可磨性指数对制粉动态模型的燃料指令增益和制粉惯性进行在线修正。
