Coal-based gangue resource utilization method based on gradient utilization concept
The invention belongs to the technical field of clean utilization of coal substances, and particularly relates to a coal-based gangue resource utilization method based on a gradient utilization concept, which comprises the following steps: crushing coal gangue; carrying out gradient classification on the crushed coal gangue product; testing the crushing value of the graded coal gangue product; carrying out secondary treatment on the crushed coal gangue with the crushing value smaller than the preset value, measuring the crushing value again, and carrying out circular treatment until the measured crushing value is not smaller than the preset value; the coal gangue broken stone with the crushing value not smaller than a preset value is screened; collecting and grinding the sieved coal gangue broken stones to prepare a cementing material or an admixture; and washing and drying the residual coal gangue broken stones as coarse and fine aggregates.
本公开属于煤物质清洁利用技术领域，具体涉及一种基于梯度利用理念的煤基矸石资源化利用方法，包括：对煤矸石进行破碎；对破碎后的煤矸石产物进行梯度分级；测试分级后的煤矸石产物的压碎值；将压碎值小于预设值的煤矸石碎石进行二次处理，再次测量压碎值，循环处理，直到所测量的压碎值不小于预设值为止；将压碎值不小于预设值的煤矸石碎石进行筛分；收集并粉磨所过筛的煤矸石碎石，制备胶凝材料或掺合料；冲洗并干燥所筛余的煤矸石碎石，用作粗细骨料。
