Frontiers Tracing the technological trajectory of coal slurry
Coal slurry pipeline transportation is an important way to realize green coal logistics. However, there are still challenges in understanding the cognitive aspects of coal slurry pipeline transportation technology development trajectory. This study attempts to trace and predict the technology trend from patent texts through the stochastic process mentation of anthracite coal, common coal, inferior coal and lignitous coal etc. Has not blocked, can eliminate impurity, has the advantages of simple structure, small in size, light weight, convenient maintenance etc. In each big, medium-sized power plant has been widely applied. 75.3 Screening and Crushing Coal Machinery 75.3.1 Crushing CoalChapter 75 Operation and Maintenance of Coal

Crushing Energy Efficiency North American Mining Magazine
Another option to help improve comminution efficiency is in-pit crushing and conveying. The advantage here is found in the transportation of ore between mine face and crusher. “Conveyors are more energy efficient that trucks,” explained TON Outotec’s Lynch-Watson and Alan Boylston, director, process engineering development, sales. 10Inventory. Life cycle inventory (LCI) is an important part of the LCA, and its precision and integrity affect the results of LCA. The inventory considered in the study is shown in Table 1.The data of environmental impact factors in each stage were from the environmental impact assessment report of Yimin opencast coal mine (HBMEP Life cycle assessment of opencast coal mine production: a
