Construction and Sorting Principle of SHP Type Wet Magnetic Field Magnetic Separator

SHP type wet high intensity magnetic separator known as Double intensity magnetic separator, imitation information foreign Jones (Jones) magnetic machine trial obtained by magnetic separation equipment.
The figure below shows the structure of the SHP-1000 wet magnetic separator. Two U -shaped magnetic coils 2 are mounted on the steel frame 1 , and the exciting coil 3 is placed on the horizontal portion of the magnetic yoke, and forced cooling is performed by an axial flow fan. The upper and lower sorting discs 5 and 6 are mounted on the vertical central axis 10 , and the disc rotates between two opposing magnetic poles, and a large closed magnetic field is formed by the U -shaped magnetic poles and the upper and lower two sorting discs. The road, while the upper and lower sorting disks are the main circuits in the magnetic circuit. There are 17 sorting chambers on the periphery of the disc, and a multi-layer magnetic cleat is installed in the chamber to become an inductive magnetic pole. The collecting pipe 8 is arranged on the disc, and the ore collecting trough 9 is arranged on the lower part, and the corresponding part of the collecting pipe is provided with a feeding nozzle.

    Sorting process: The slurry is fed into the sorting chamber from the feeding point at the magnetic field inlet, and then enters the magnetic field and passes through the gap of the tooth plate. The non-magnetic ore particles are not attracted by the tooth plate and fall into the tailings trough, weak magnetic minerals. It is adsorbed around the tip of the high magnetic force, and is transferred with the ring about 60 ° , where the magnetic force is low, and it is flushed into the concentrate tank by high pressure water, and the magnetic properties can be extracted between the concentrate and the tailings. The product. The magnetic separator has four feeding points, which can be independently sorted. Therefore, different processes of different samples can be tested simultaneously on a single machine.
The structure of the device is relatively simple, easy to manufacture, high magnetic field strength, and the maximum field strength of the gap between the indoor tooth plates can be up to 1280 kA/m, and the operation is stable and adaptable. It can handle fine disseminated weak magnetic hematite, hematite iron ore and exposing the like. In some of China's factories and mines have been used, such as Dabaoshan, Jiuquan Iron and Steel Company beneficiation plant. The WISCO Daye Iron Ore Concentrator has a good selection effect.
The main problem in use: there is still clogging phenomenon, the fine-grain class selection effect of less than 0.037 mm is not good; in addition, the unit machine weight processing capacity is small, and the noise of the cooling phoenix machine is large.
The operating factors of this magnetic separator include: magnetic field strength, rotational speed of the sorting disc, ore supply and ore concentration.
