This machine is a cylindrical external filter vacuum permanent magnet filter with upper feeding. The ferrite permanent magnet system is installed inside the barrel, which can prompt the magnetic particles to be adsorbed on the filter cloth surface quickly. Because the upper feeding, the concentrate filter cake according to intensity layered effect is more obvious. When the cake is formed when the magnetic concentrate particles, at the same time by gravity and magnetic force. The coarse concentrate ratio of fine particles to concentrate the cloth movement quickly, fine grain first contact cloth, so the filter cake permeability, and magnetic the pulp in the magnetic attraction of particles radially distributed in the surface of the cylinder, and the magnetic polarity change of magnetic stirring, it will become the favorable conditions of filter cake easy to dehydration, the cake thickness and permeability, significantly improve productivity.

Applicable scope
GYW series vacuum permanent magnetic filter is mainly suitable for dehydration of coarse particles of strong magnetic material. The best working conditions of the filter for solid particles in the pulp than the susceptibility of not less than 3000 x 10 cm, -6, 3/ g, 0.12-0.8mm particle size, the feed concentration is more than 60%.

Technical characteristics
Feeding, blowing, adsorption, cake, dehydration, unloading, cleaning and other parts of the continuous action completed.
Depending on the open magnetic system arranged in the cylinder with the permanent magnet of strontium ferrite and the upper feeding, the layering effect of the mineral particles in the filter cake is obvious, and the cake thickness is large and the air permeability is good.
The magnetic material is adsorbed on the filter cloth under the magnetic force and the gravity of the particle itself, and the adsorption speed is fast and the efficiency is high. Compared with the cylindrical vacuum filter with the same specifications, the production efficiency is increased by more than three times.
When the cylinder is transferred into the dehydration zone, the residual water in the filter cake is filtered through the filter cloth and filtered out through the two vacuum pipes in the filter chamber and the distributor head, and the moisture content of the cake is low
After the material is dehydrated, the compressed air is used to unload the material, and the discharging speed is fast.
The filter cloth is cleaned by blast and water alternately, and compressed air is forced to blow the water out of the cylinder to form a better cleaning process, which prevents the clogging of the filter cloth pores and provides good conditions for the dewatering of the materials
The operation performance is stable, the operation is simple, and the filter cloth replacement is convenient.
