长期以来,人们一直在努力寻求降低湿式介质研磨设备高能耗的方法。笔者从一篇专业论文中注意到,在湿式研磨粉碎过程中使用化学添加剂来改善物料的特性,便能提高物料的可粉碎性。为此,笔者作了广泛调查研究,以磁性氧化铁(又称四氧化三铁,以颜料和擦光剂原料为物料,配以不同的添加剂进行试验。结果证明,使用氧化钙为添加剂,物料的粉碎效果明显改善。电子扫描显微照片表明,在氧化钙添加剂作用下,磁性氧化铁表面蜂窝结构组织骤增,因而变得松脆,易于粉碎。
For a long time, people have been trying to find ways to reduce the energy consumption of wet media grinding equipment. The author from a professional paper noted that the use of chemical additives in the wet grinding and grinding process to improve the properties of the material, can improve the crushability of the material. To this end, I made a wide range of investigations and studies to magnetic iron oxide (also known as ferric oxide, pigments and polishing materials raw materials, with different additives tested.The results show that the use of calcium oxide as an additive, materials Of the grinding effect was significantly improved.Electron scanning micrographs show that in the calcium oxide additives, the magnetic iron oxide surface of the honeycomb structure of the sudden increase, which became brittle, easy to crush.
