近几年来,永磁圆筒磁选机在磁选厂得到了广泛应用,同时在处理氧化矿石的选矿厂用于予先把磁铁矿和假象、半假象赤铁矿物选成合格铁精矿也是有效的。我们自制了两台φ400×300毫米的锶铁氧体永磁圆筒磁选机,因磁块质量较差,加之磁块组装时未进行磁性检测,故总装后该机圆筒表面的场强仅达1000～1100奥斯特。后来,我们对其中的一台进行了提高场强的工作,即将原来的开放磁系变为闭合磁系,结果圆筒表面磁场强度由原来的1000～1100奥斯特提高到2600奥斯特。试验证明:改进
In recent years, the permanent magnetic separator magnetic separator has been widely used in magnetic separation plant, while dealing with the ore ore processing plant used for pre-magnetite and illusion, semi-artificial hematite hematite selected qualified iron Mine is also effective. We made two sets of φ400 × 300 mm strontium ferrite permanent magnetic separator, because of the poor quality of the magnet, coupled with the magnetic assembly did not make magnetic testing, so after the assembly of the aircraft surface strength of the cylinder Only up to 1000 ~ 1100 Auster. Later, one of our work was carried out to increase the field strength, that is, to turn the original open magnetic system into a closed magnetic system. As a result, the magnetic field strength on the cylindrical surface was raised from the original 1000 to 1100 Oersteds to 2600 Oersteds. Test proved: improvement
