Ceramsite proppant added with magnetite and preparation method of ceramsite proppant
The invention discloses a magnetite-added ceramsite proppant and a preparation method thereof, and relates to the technical field of ceramsite proppant preparation, the magnetite-added ceramsite proppant comprises the following raw materials by weight: 20%-40% of calcined bauxite A, 30%-50% of calcined bauxite B, 0%-10% of white crucible soil, 10%-30% of gangue, and 3%-5% of magnetite. According to the invention, high-grade magnetite is added to replace expensive manganese powder, so that the purpose of reducing the cost of raw materials is achieved, ground calcined clinker is added to the formula, so that the purpose of artificially introducing mullite seed crystals and a glass phase is achieved, mullite crystals can be increased and the firing temperature range can be widened during secondary firing, and the production cost is reduced. Therefore, the purpose of improving the yield is achieved, and the yield reaches 96% or above.
本发明公开了一种添加磁铁矿的陶粒支撑剂及其制备方法，涉及陶粒支撑剂制备技术领域，所使用原料按重量百分占比计包括熟铝矾土A 20％‑40％、熟铝矾土B 30％‑50％、白坩土0％‑10％、矸石10％‑30％、磁铁矿3％‑5％。本发明通过在配料中加入高品位的磁铁矿替代价格高昂的锰粉，从而达到降低原料成本的目的，通过将磨细后的煅烧熟料加入配方中，达到人为引进莫来晶种和玻璃相的目的，在二次烧成中既可使莫来晶体增加又能增宽烧成温度范围，进而达到了提高成品率的目的，令成品率达到96％以上。
