Material: Cordierite, Mullite, Alundum mullite., Shape: Square and round., Application: Foundry, molten metal filtration. - details see: https://www.machineto.com/extruded-ceramic-filter-cordierite-mullite-alundum-mullite-10219506

Extruded ceramic filter is a fine strainer with straight hole structure, which provides a cost-efficient alternative to more effective ceramic foam filter.

We can produce different size of extruded ceramic filter; they have better handling properties than ceramic foam filters.

The advantages of extruded ceramic filter as follows:

Geometrical shape.

High dimensional accuracy.

Good mechanical and handling properties.

Maximum service temperature 1450°C, it is applied to grey iron, ductile iron and malleable iron. Grey iron requires cell diameters of less than or equal to 2 mm, spheroidal graphite iron requires cell diameters of 2 mm and greater.
