1.Product Information
The magnetic rod filter(Magnetic grid) is a device or equipment processed and manufactured with a magnetic rod as the core part, a drawer type iron remover, and a slurry iron remover. The simplest is a single-layer grid, which consists of four magnetic rods, a stainless-steel shell and a bracket. At the same time, it can be divided into single layer, double layer, and multilayer. Usually square and round, if necessary, the shape can be customized according to customer drawings.
In order to facilitate cleaning, the product also has an easy-to-clean version, and the magnetic rod can be drawn out to facilitate cleaning of the stainless-steel housing. In order to reach the best condition again.
In addition, magnetic filter equipment with automatic devices can be designed according to the available needs to increase the filtering effect and reduce manual operations.

Cleaning method
Once the magnetic or weak magnetic substance is adsorbed on the strong magnetic rod, it is usually more difficult to remove, so the easy-to-clean design is a best practice in the industry.
The easy-to-clean design is to add a jacket to the outside of the magnetic rod. After the magnetic rod is extracted, the magnetism on the jacket disappears and the adsorbed foreign matter will fall off automatically. As shown below.

Ferromagnetic material: It is a metal that greatly enhances the original material, mainly iron (Fe), cobalt (co), nickel (Ni)
Paramagnetic substances: Metals that increase the original substance to a small extent, mainly (lithium (Li), sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), strontium (Sr), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), etc.
Diamagnetic material: Under the action of a magnetic field, it produces an additional magnetic field opposite to the external magnetic field, which can be understood as weakening the original magnetic field. Copper (Cu), silver (Ag), gold (Au), cadmium (Cd), and mercury (Hg) in metals are all diamagnetic substances.
