Method for preparing ceramsite sand based on blast furnace slag and iron tailings
The invention discloses a method for preparing ceramsite sand based on blast furnace slag and iron tailings. The method specifically comprises the steps of S1, material preparation, S2, grinding, S3, mixing, S4, granulation, S5, drying, S6, sintering and S7, screening and grading (according to the particle size) after discharging from a furnace and packaging. The ceramsite sand is produced by utilizing industrial wastes, namely the blast furnace slag and the iron tailings, waste utilization of the blast furnace slag and the iron tailings is realized, and the ceramsite sand produced by adopting the method can also be used as a petroleum fracturing propping agent and has the characteristic of lower production cost.
本发明公开了一种基于高炉渣和铁尾矿制备陶粒砂的方法，具体包括S1备料，S2研磨，S3混合，S4造粒，S5烘干，S6烧结，S7出炉后筛选分级（按照颗粒大小）包装。通过利用工业废弃物高炉渣和铁尾矿，生产制造出陶粒砂，实现了高炉渣和铁尾矿的废物利用，采用本方法生产制造的陶粒砂亦可作为石油压裂支撑剂，具有生产成本更低的特点。
