磁力脱水槽在国内磁选厂中已成为广泛使用的主要设备,在磁选中发挥了很大的作用。目前各选矿厂所使用的型式虽有所不同,但就结构来说是大同小异的,磁路原理也是一致的。各厂所用脱水槽的磁场强度一般为150至200奥斯特,部分的可达到300至500奥斯特,总的来说都是比较低,而影响了脱水槽的选别效果。近年来很多单位对提高现有脱水槽的磁场强度进行了不少研究,取得了一些效果,但不够显著。我们根据现场所用脱水槽的型式,对小型磁力脱水槽进行了一些研究和测定,研究结果表明,只要对现有脱水槽的中央磁极(现场称给水筒)稍作改进,在其他条件完
Magnetic dehydration tank in the domestic magnetic separation plant has become widely used as the main equipment in the magnetic separation has played a significant role. At present, the types of ore dressing plant used are different, but the structure is more or less the same, the magnetic circuit principle is the same. Dehydration tank used by the factory magnetic field strength is generally 150 to 200 Oersted, some can reach 300 to 500 Oersted, in general, are relatively low, which affected the dehydration tank sorting effect. In recent years, many units to improve the existing dehydration tank magnetic field strength of a lot of research, and achieved some results, but not significant enough. According to the type of dewatering tank used in the field, some researches and measurements have been made on the miniature dewatering tank. The results show that as long as the central magnetic pole of the existing dewatering tank (called the water tank) is slightly improved,
