JB/T16641999
This standard is a revision of JB1664-75 "Permanent magnetic dewatering tank". Compared with JB1664-75, the main technical content of this standard is the addition of "top magnetic system" in the magnetic system type, and the expression method is given to distinguish "tower type magnetic system". This standard replaces JB1664-75 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Standardization of Mining Machinery. The responsible drafting unit of this standard: Shenyang Mineral Processing Machinery Research Institute. The main drafters of this standard are Li Wenqi, Wang Yanhua, Li Jun, Liu Yuheng and Huang Jialin. 1 ScopewwW.bzxz.Net
