Iron Ore Dressing Equipment Drum Vacuum Filter

GWT vacuum filter machines manufacturer price vacuum rotary drum filter is the solid-liquid separation
equipment driven by vacuum negative pressure with the advantages of high filtration efficiency, production
capacity, washing effect, low cake moisture, flexible operation, low maintenance cost and so on.
Especially for the magnetic minerals dehydration, this machine is 3 times bigger than other filter capacity.
Widely used in metallurgy, mining, chemical, paper, food, pharmaceutical, environmental protection and
other areas.

GWT series vacuum permanent magnet is a tube-type permanent magnet outside the filter vacuum filter,
mainly applied to coarse particles of magnetic materials dehydration.The best working conditions of this
series filter: pulp Solid particles coefficient than the magnetization of not less than 3000 × 10-6 (cm3 / g),
particle size is 0.15-0.80mm, feed concentrations of 60%.


PRINCIPLE: Filter mainly rely on the effect of open magnetic system which rowed by permanent magnet
internal the cylinder, to form filter cake. When the magnetic materials putted in to feedbox, the solid
particles of magnetic material absorbed to the cylinder filter repidly as magnetic cluster, under the
magnetic effects and their own gravity (At the moment, it can make use of amount of compressed air to
blast to help the mineral particles on the filter cake layering by granularity). 

Due to the upper material, the effect of layering the mineral among the filter cake by granularity is more
obviously, thick structure with great permeability along with the drive cylinder enter the dewatering zone.
On the effect of vacuum, the residual water among the filter cake through the filter, then pass the screening
room and the two heads of vacuum tube distribution road be singled out. Meterials that have been
dehydrated blowed down by the compressed air in unloading zone. Filter access to clean area after
discharge. Cleaning is the turn of the blast and water. Forced by the compressed air, the water was
blowed out of the cylinder so that established a better cleaning process. prevented the plug of filter pore,
and prepare good conditions for next dehydration of the materials.

 
The drum filter of external filtration are widely used in the department of oredressing,metallurgy,chemical
industry, and papermaking.It is mainly specilized in dehydrating for clean coal ,nonferrous metal
concentrate(copper,zinc,aluminium,and nickel..),and nonmetal concentrate(sulphur,phosphorus,talc,and
fluorite..) after flotation.And it is also applicated to solid-liquid separation of suspension which is difficult
to precipitation.
