Coal Gangue Bricks Technology Africa

  • Coal Gangue |

    Abstract: The current statistics show coal gangue discharge is 100 million tons per year, and the accumulated discharge has been as high as 45 billion tons It comprises the largest portion of solid waste in our country Its storage not only requires valuable land resources, but also pollutes the air, water and soil of the storage sitesTools Share Abstract Nephelinebased waterpermeable bricks are prepared with coal gangue and aluminum hydroxide by raw material pretreating, mixing, isostatic molding, roasting, and selfcuring These bricks exhibit balance between their mechanical and waterpermeable propertiesNepheline‐based water‐permeable bricks from coalThe energy in coal gangue functions in the process of brick making to realize the save of raw coals In addition to the need of coal gangue to be crushed, the other production process is basically the same as that of clay bricks CaO in coal gangue is a harmful component in the sintering of prehensive utilization and environmental risks of coal
