试验室XCQS-Ф50型磁选管技术参数
Technical Parameters of Laboratory Magnetic Tube

XCQS74-Ф50、XCQS73-Ф50型磁选管即戴维斯分析管，适用于矿山、冶金、地质等实验室。是选矿过程中，用来测定强磁性矿石中强磁性成分含量的一种设备。

磁选管是在C型电磁铁的两极端之间，装有玻璃管作往复移动和摆动。被分选的试料在通过磁场区时，磁性部分即附管壁附近。非磁性部分在机械运动中被水冲刷而排出。本产品由原地矿部唯一指定企业生产，执行行业标准。

XCQS74-Ф50、XCQS73-Ф50 Magnetic Tube or Davis Analyzing Tube is applicable  in labs.of mine, metallurgical, geological and other industries. It is designed to determine magnetic content in strong magnetic mineral in the mineral processing operation.

Magnetic Tube is C Type electromagnet fitted with glass tube between pole ends to reciprocately move and swing. When the test materials to be separated pass through magnetic fields, the magnetic portion will be absorbed near the tube walls and the non- magnetic portion will be washed down by water in the mechanical movement and discharged . The product is produced by the only enterprise designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

XCQS74-Ф50 magnetic tube lies between the two ends of electromagnet. It is equipped with glass tube to reciprocate and swing. When the sorted samples pass the magnetic field, the magnetic parts get close to the tube wall. The non magnetic parts are discharged after washed away by water during mechanical movement.
