A dry magnetic separation equipment for the pre-selection of coarse-grained strong magnetic minerals. 【Processing capacity】: 100t/h-350t/h 【Scope of application】: It is used for dry pre-selection of magnetite before grinding, and the selected particle size is below 300mm. Usually, the tail can be thrown in an appropriate amount to improve the grinding grade to above the geological grade.
The magnetic system of Xinhai strong magnetic drum adopts NdFeB magnets with high magnetic energy product and high coercivity, with high magnetic field strength and large working depth;
The demagnetization rate of the magnetic field strength in 8 years does not exceed 5%;
The magnetic system package is made of non-magnetic stainless steel to ensure that the magnet does not fall off;
The cylinder body of the strong magnetic drum is made of non-magnetic stainless steel and covered with wear-resistant rubber, and the service life of the cylinder body is significantly improved;
The permanent magnet drum can be used as both a driving drum and a driven drum.
The materials are uniformly fed to the belt. When materials go through the permanent magnetic drum, the non-magnetic and low-magnetic particles will leave the belt surface because of the centrifugal force and gravitation. Meanwhile, strong-magnetic particles are absorbed to the belt by the magnetic force and then fall into the magnetic trough when the belt leaves the magnetic pulley.

In an iron concentrate beneficiation plant, the lean iron ore is subjected to magnetic separation after coarse crushing and secondary crushing. In order to restore the grade, save energy and increase production, a permanent magnet drum magnetic separator is selected to reduce the load of the next process. Two-stage magnetic separation is arranged, the magnetic field strength is large, the magnetic separation effect is very obvious, and the production efficiency is improved; at the same time, it can also be used for the treatment of tailings, which is conducive to the reuse of equipment, saves costs, and improves the quality.
