Model: the CTB-718, the cylinder diameter: 750mm, cylinder length: 1800mm, cylindrical surface of the magnetic induction intensity :155-380mt, speed: 35r/min processing capacity :20-45t / h, 72m3 / h, the motor power : 3KW 
 Permanent magnet drum magnetic separator for wet separation of fine particles of magnetic minerals, minerals are to be elected than the susceptibility is generally not less than 3000 × 10 ˉ 6 cm and 3 cm / g. Belong to this type of mineral magnetite, pyrrhotite iron ore or magnetizing roasting of hematite, limonite, siderite, etc.. 
 Pulp to the mining area to mine box into the separator tank, loose state to enter through the magnetic field, which magnetic strong mineral particles in the role of the magnetic field, adsorption on a cylindrical surface, the cylinder rotation process magnetic mineral particles in a chain, flip, and inclusions in the magnetic mineral part of the pulse quarry particles and sediment erosion by water discharge, magnetic mineral particles with the cylinder rotation, was taken out of the mine district water into the clear mines non-magnetic minerals to get rid of, the role of the tank slurry flow discharge from the tailings slot, thus completing the separation process. 
 The main structure: cylindrical permanent magnet, gear, tank, rack, adjusting device of the magnetic system to mine box concentrates box, the downstream trough and tailings regulating valve.
