Grinding medium for copper-cobalt ore grinding
The invention discloses a grinding medium for copper-cobalt ore grinding, which is prepared by the following steps: 1) adding modified kaolin, argil, silicon dioxide, calcium oxide, zirconium silicate, silicon carbide, silicon nitride and white mica into a ball mill, ball-milling to 1500-1800 meshes, and discharging to obtain superfine powder; (2) extruding the mixed raw material in an extruder at 1300-1580 DEG C, and rapidly cooling and shaping the extruded mixed raw material under the impact of a high-pressure water gun to form a spherical particle grinding medium; (3) screening the grinding medium, crushing the medium larger than 5mm, screening again after crushing, and selecting particles smaller than 5mm in particle size as qualified particles; and 4) placing the grinding medium particles in a hydrochloric acid solution to remove impurities, then washing with clear water, and drying in a drying oven to obtain a finished product. The hardness, the mechanical strength, the corrosion resistance and the heat resistance of the grinding medium are improved, and meanwhile, according to the matched processing technology, a high-pressure water gun is adopted for rapidly cooling and forming raw materials in a molten state, so that the processing rate of the grinding medium is greatly increased.
本发明公开了一种用于铜钴磨矿的研磨介质，如下步骤：1)将改性高岭土、陶土、二氧化硅、氧化钙、硅酸锆、碳化硅、氮化硅以及白云母加入到球磨机中，球磨至1500‑1800目后，出料，得超微粉末；2)将混合原料置于1300‑1580℃挤出机中挤出，并与高压水枪的冲击下快速冷却定型成球状颗粒研磨介质；3)将研磨介质进行筛分，大于5毫米的介质进行破碎，破碎后再次过筛，选取粒径小于5毫米颗粒作为合格颗粒；4)将研磨介质颗粒置于盐酸溶液中去除杂质，然后用清水冲洗干净，于烘箱中烘干即为成品；这种研磨介质的硬度、机械强度及耐腐耐热性能得到提升，同时配套的加工工艺采用高压水枪对熔融状态的原料进行快速冷却成型，使得本研磨介质的加工速率大大提高。
