Processing raw material and preparation method of fused magnesite
The invention discloses a processing raw material of fused magnesite, and a preparation method thereof. The fused magnesite comprises the following raw materials in parts by weight: 40-50 parts of flotation powder with a particle size of less than or equal to 2 mm, 20-30 parts of magnesite powder with a particle size of less than or equal to 15 mm, 20-30 parts of fused magnesium smelting auxiliarymaterials with a particle size of less than or equal to 10 mm, 10-15 parts of light calcined magnesia powder with a particle size of less than or equal to 1 mm and 10-15 parts of water. Compared withthe prior art, the method of the invention has the beneficial effects that the balling rate and the strength of finished balls can be effectively improved without adding a chemical binding agent, theproblems that the production cost is increased due to addition of the chemical binding agent and the binding agent pollutes the environment in the fused magnesia smelting process are solved, and theproblem that electric energy is wasted due to the fact that the compactor and the ball press wait for no-load operation of mixed materials because the mixing time and the pressing time are not matchedin the ball pressing process is solved.
一种电熔镁砂的加工原料及其制备方法，包括下列重量份数的原料：粒径≤2mm的浮选粉40‑50份、粒径≤15mm的菱镁矿粉20‑30份、粒径≤10mm的电熔镁熔炼辅料20‑30份、粒径≤1mm的轻烧氧化镁粉10‑15份、水10‑15份。与现有技术相比，本发明的有益效果是：本发明不需要添加化学结合剂，即可有效提高成球率及成品球强度，避免由于添加化学结合剂所增加的生产成本问题以及在电熔镁砂熔炼过程中结合剂的污染环境问题。另外，本发明解决了压球过程混拌时间与压制时间不匹配造成压密机、压球机等待混拌物料空载运行浪费电能的问题。
