1. The GYW vacuum permanent magnet filter is the external filtering drum permanent magnetic vacuum filter for the upper feeding. It's applicable to magnetic materials of coarse particles dehydration
2. The best working condition of the filter is
The specific susceptibility of solid particles in the pulp is not less than 3000×0.000001cm3/g.
The particle size is 0.12-0.8mm.
The feed concentration is greater than or equal to 60%.
working principle:
When the vacuum filter vacuum suction pressure caused by power as a filter, a combination of the body dispensing head, actuator, discharge mechanism is made, many of axially spaced apart filter chamber, filter work on the body, speed motor-driven rotating body, the filter can be immersed in the slurry, the interior is vacuum evacuated to a negative pressure in the slurry liquid into the filter cavity through the filter cloth become filtrate from the plane through the dispensing head, cloth material attached to the outside of the solid on the cloth became cake. The dispensing head one week into the filter dry filter zones, dewatering zone, unloading zone cloth washing area. Dispensing head control each filter chamber during rotation of the body through these areas in turn, form a filter cake, suck out the water, cake discharge, cleaning cloth and other processes.

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.
Selection Criteria
In broad terms drum filters are suitable to the following process requirements:
Slurries with solids that do not tend to settle rapidly and will remain in a uniform suspension under gentle agitation.
Cakes when a single washing stage is sufficient to remove residual contaminants from the cake or yield maximum recovery of filtrate.
Cakes which do not require long drying times to reach asymptotic moisture values.
Filtrates that generally do not require a sharp separation between the mother and wash filtrates. Some complex valves, however, enable atmospheric purging of the sectors and internal piping to facilitate a sharp separation of filtrates.
Filtrates that are acceptable with a low quantity of fines that pass trough the filter cloth in the first few seconds of cake formation. Broadly, and depending on particle size and cloth permeability, the filtrate may contain 1000 to 5000 ppm insolubles.
For very corrosive applications plastic drum filters are available with up to 10-15 m2 filtration area.
