Method for preparing ceramsite from coal-based solid waste
The invention discloses a method for preparing ceramsite by using coal-based solid waste, which comprises the following steps: classifying according to different plasticity of coal-based solid waste raw materials to obtain ceramsite raw materials; and after drying the ceramsite raw material, arranging an auxiliary combustion area in an interval of 800-1000 DEG C for decarburization, and roasting in an interval of 1000-1200 DEG C. The coal-based solid waste is efficiently utilized, an optimized roasting method is adopted, the full-solid waste ceramsite product is prepared, and the mechanical property of the product is excellent; and the process is simple, is suitable for industrial popularization and application, can be used as a building lightweight aggregate or a building gravel material, and has excellent environmental benefits, economic benefits and social benefits. The method is suitable for the field of coal-based solid waste utilization.
本发明公开了一种利用煤基固废制备陶粒的方法，所述方法包括：根据煤基固废原料塑性的不同进行分类，得到陶粒生料；将所述陶粒生料干燥后，在800‑1000℃区间内设置辅助燃烧区进行脱碳，在1000‑1200℃区间内进行焙烧。本发明针对煤基固废进行高效利用，采用优化的焙烧方法，实现全固废陶粒产品制备，产品力学性能优良；且工艺简单，适合工业化推广应用，可作为建筑轻集料或建筑砂石料，具有优异环境效益、经济效益和社会效益。本发明适用于煤基固废利用领域。
