Research on a Coal Gangue Identification Device
Applied Mechanics and Materials, 2013The paper designed a coal gangue identification device. It firstly proposed to use the guide groove to guide, grayscale sensor to recognize and the corresponding mechanical actuators to realize automatic separation of coal and waste rocks. Compared with other separation device, it firstly put forward solutions to realize the linear arrangement of ...

Identification and Activation of Coal Gangue and Performance of Limestone Calcined Gangue Cement
2020Gangue, a typical waste associated with the coal mining process in northern China, was characterized before and after thermal treatment by XRF, XRD, TGA-DSC, and SEM. The pozzolanic reactivity of calcined gangue with different calcined temperature was tested by standard mortar strength and R3 calorimetry test.
