The use of ceramic filter can separate the molten aluminum with its metallic impurities from solid particulate material, mainly particles which are caught up in the scrap metal.
The ceramic foam filter uses a highly porous material as an intermediate for liquid aluminum to pass through the pores, trapping solid particles on the other side of the medium to achieve the separation goal.
Use of Ceramic Foam Filter
A ceramic foam filter is a technique that uses porous materials (such as filter materials such as filter cloth) to separate solids from liquids.
Under the influence of the pressure difference on both sides of the filter medium, the liquid passes through the filter medium and becomes a filter.
Filter out any particulate matter remaining on the filter material, such as filter cake.
Filtration can produce a filter cake with lower water content and a filter without particulate matter.
Filtration cannot be classified by particle size compared to other solid-liquid separation methods, but it uses less energy.
Since the pores of the filter media are easily clogged with fine solids, the filtration method is more suitable for filling joints with larger solids or less solids.
In surface filtration, filter cloth, filter plates, porous materials, and powder are mainly used as filter materials, and solid particles are suspended and accumulated on the surface of the filter materials.
The pore size of the filter material is not necessarily less than the supported particle size.
At the beginning of the filtration operation, a small number of fine particles can pass through the medium and mix with the Ceramic Foam Filter China, and at the same time, the particles become clogged in the mesh, gradually forming a truly effective filtration medium.
Surface filtration is suitable for items with high particulate content, for example over 1%.
Due to clogging, the filtration resistance increases sharply. The resistance of the filter cake is much higher than the resistance of the filter medium, which decisively affects the filtering capacity.
