Description

Magnetic Filters

Magnetic filter is composed of the filter body and the magnetic bars, it is connecting inlet and outlet production pipes through flange, threaded or clamp type connections.

Magnetic filters are designed to filter and remove ferrous contamination or fine iron impurities/tramps from different viscosity level liquid, slurry, air conveying pipeline powder, gas and other materials. Magnetic filter is an ideal magnetic system for preserving product purity by removing small contaminants and providing magnetic protection for processing equipments of liquid lines.

Working principle of Magnetic Filters:

In the special process of production, the ferrous material passing by the magnetic bar, under the attraction of rods, all those impurity ferrous material will be absorbed on the rods, so as to ensure safety of the equipments and products.

4. Applications Of Magnetic Filters

 

Magnetic filter is mainly used to remove metals such as impure magnetic powder, granular in chocolate, water, honey, juice, slurry or something like liquid. It is widely used in ceramics, electricity, mining, plastics, chemicals, rubber, food, environmental, pigments, dyes, electronics, metallurgy, etc.

 

5. How to clean the magnetic filters:

Frequency of cleaning of magnetic filters: it depends on iron impurities contents and treated liquid flow or materials flow per hour. Normally the thickness of powdery iron impurity absorbed onto the surface of magnetic bars should not exceed 10mm. To main the best working performance, magnetic bars shall be cleaned regularly and timely.

Magnetic filters cleaning method:

-Open the fixing screw of magnetic core/bar/rod

-Take out the bars

-Clean the impurities adsorbed on the iron rod surface

-After cleaning, put the magnetic bars into body, fix it. To avoid material or liquid leakage during magnetic filters working caused of sealing ring dislocation, please check and confirm the O-ring (sealing ring) is completely stuck in the sealing gasket groove.

-When cleaning the iron impurities on the surface of magnetic bars, you can use thick cotton gloves, towels, trays and other tools. When it is necessary, you can use clean magnetic bars with clear water.
