Magnetic Drum Separator

Magnetic drum separators are primarily designed and manufactured as low field intensity separators. They have an open magnetic system with the magnetic poles located in one plain. (magnetic drum separators)low field intensity separators are employed for separating iron particles from bulk material whenever foreign iron disturbs the subsequent process sequences. It is also used for removing or enriching strongly magnetic content of dry minerals.

Working of permanent magnet drum separator:
After the ore slurry tank into the tank after the water pipe water to the mine under the influence of mineral particles into the tank was loose state of a mine. The role of the magnetic field, magnetic mineral particles to the magnetic pole movement magnetic agglomeration occurs, and be attracted to the cylinder. (magnetic drum separators) the polarity of the magnetic poles along the alternating direction of cylinder rotation, and at work be fixed, due to alternating magnetic pole magnetic stirring produced the phenomenon of non-magnetic minerals in the turning off, and eventually the suction surface of the cylinder is a concentrate. (magnetic drum separators)concentrate along the edge of magnetic cylinder to the weakest at the magnetic system, mineral water spray in the unloading effect of flushing water was discharged into the concentrate tank, if it is full magnetic magnetic roller, brush roll unloading ore is carried out with . Non-magnetic or weakly magnetic minerals are left with the pulp slurry in the discharge groove, that is tailings.

Permanent magnet drum separator structure:
Permanent magnet drum separator mainly by the cylinder, roller, brush roller, magnetic system, tank, transmission parts 6 parts. (magnetic drum separators) cylinder by a 2-3mm stainless steel plate welded into the tube, end caps for the aluminum casting or workpiece, connected with stainless steel screws and barrel. Motor or directly through the reducer promise speed motor, drive cylinder, magnetic roller and the brush roll for rotational movement. Magnetic system is an open magnetic system, mounted on the cylinder and exposed full magnetic. (magnetic drum separators) magnets with stainless steel bolts installed in the magnetic yoke of the floor, out of cylinder yoke shaft, the shaft has shui arm fixed. Pulled the magnetic system can be adjusted shui arm angle adjustment lever can be fixed after appropriate. Tank work area with stainless steel plate, frame and other parts of the tank with ordinary steel welding.

Permanent magnetic drum separator
Permanent drum type magnetic separator is most useful non electric separator for separating tramp iron from non magnetic material processed in bulk quantity for the purity of end products, recovery of metal having commercial value and protection of processing plant and machinery. These are widely used in all the processing industry for separation of iron contamination from mineral, chemicals, food, flour plastics, grains, sand, cement, fertilizers, abrasives, glass, slag, ores, rock, refractor and any other products.

Size range
The permanent drum separators are available in standard drum diameters of 300mm, 400 mm. Drum width range from 300mm to 1200mm. Other sizes can be made as special to your requirement. The larger the diameter and width of the drum the greater is the volume of material which can be handled.

Salient features:-

• Drum consists of high energy rare earth neodymium permanent magnets.
• Strong & rugged construction. Automatic separator of iron impurities.
• Completely enclosed design to avoid dusting and pollution.

Working principle & magnetic system
The  permanent  magnetic  drum  consists  of  stationery  permanent  magnetic assembly having uniform and everlasting magnetic field across the entire width of the drum, which is effective over approximately half the drum circumference. Drum shell made of non magnetic stainless steel revolves around the magnetic field. As the material feed evenly from the chute falls over the drum, powerful-magnetic, field attracts and holds ferrous particles to the revolving shell. As the revolving shell carriers the iron particles through the stationery magnetic field, the non magnetic material falls freely from the shell while ferrous particles are firmly held till carried beyond divider and out of magnetic field. The strength of the permanent magnetic drum is guaranteed to be grater than corresponding electromagnetic drum.

Closed type drum separator  
The totally enclosed type drum comes complete with a chute type feeder, hopper, adjustable feed regulation gate, magnetic drum and geared motor drive in a ready for use condition. Inlet and outlet openings are flanged for ease of connection to customers duck work. Double or triple totally enclosed machines can also be supplied if required by clients.

Wet drum separator
Star trace's wet permanent magnetic separators are offered in size of dia 1200mm (48`) and 916mm (36`) ion lengths of up to 3000mm (10`). Three basic separator designs are available for copping, roughing and finishing / cleaning applications. Each type can be supplied in single drum or multiple drum stages of taconite or magnetic and also for recovery for magnetic medium in dense media plants.

The stationery magnet yoke is an assembly of rare earth neodymium permanent mmagnets. The rotating drum is available with optional rubber or stainless steel covers. The magnetic flux pattern will match the tank configuration for optimum performance.
