Product Description:

 Ceramic Foam Filter has the advantages of high porosity, good thermal shock resistance,high mechanical strength, large specific surface and stable chemical property. In addition, with the excellent function of filtering, residuum collection and absorption, it can remove the impurities of 1-10μm efficiently. The outstanding three dimensional structure can reduce the turbulence and extrude the air in mould filling, provide consistent and rapid metal flow, improve the casting quality prominently.Ceramic Foam Filter can also be applied in gas treatment at high temperature, carrier of catalyzer, solid thermal exchange and special filling for chemical industry.
With more than ten years of research and development, enriches its product scope with different series of foam filters such as Alumina, Silicon Carbide and Zirconia.
Alumina foam filter (JG-1): For molten metal filtering under the temperature of 1200
;
Silicon Carbide foam filter (JG-201, JG-202): For molten metal filtering under the temperature of 1550

Zirconia foam filter (JG-3): For molten metal filtering under temperature of 1700.

APPLICATION OF  CERAMIC FOAM FILTER
Selection of 
 ceramic foam filter
1) Selection of pore size is based on the weight and material of casting, regularly 10ppi for Stainless Steel; 10ppi for Ductile Iron; 20ppi for Grey Iron; 15ppi, 20ppi and 30ppi for non-ferrous alloy castings:
2) Foam filter size is decided by the sculpt, fusion and the characteristic of the ceramic foam filters.
3)'Ceramic foam filters should be fixed in the runner and ensure its uniform pressure.
4) Strictly control the pouring pressure and reduce the impact of hot molten metal.
5) Ceramic foam filters under ultra-high temperature are prohibited.
6) Strictly avoid using the ceramic foam filters to control the flow speed of molten metals

Attentions for store and application
Ceramic foam filters should be stored in dry environment to avoid moisture. Ceramic foam filters are fragile materials, rough handling in transportation is prohibited.  It is recommended to blow the scum with compressed air before using

The advantage of application ofceramic foam filter
1) Reduce the defective rate and improve the casting yield.
2) Reduce the machining allowances and improve machinability of casting.
3) Improve the mechanical property of casting
4) Simplify pouring systems and improve the utilization ratio of mould


TYPICAL INSTALLATION OF CERAMIC FOAM FILTERS

Based on the characteristic of casting and the filters' working condition, ceramic foam filters can be fixed in different parts of the pouring system

1、Installation in the pouring cup: Commonly for precision casting and the casting of iron model covers the granulated substance
2、Horizontal installation in vertical runner: For small part with few pouring molten iron, especially for casting system with a vertical runner located at mould center and multiple branches of horizontal runner
3、Horizontally installation in horizontal runner: It makes molten metal casting stable, avoiding directly impacting the filter. This will increase slag blocking ability and make installation convenient.
4、Vertically installation in horizontal runner: To increase molten metal flow speed and enhance the filling capacity. Since molten metal directly impacts the fillers, the impact resistance of filters should be considered

Q:Ceramic filter capacity.
60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.
Q:Microporous ceramic filter plate cleaning
Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.
Q:Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems
Equipment comes with cleaning:Ceramic filter comes with a combined cleaning system, usually to ensure the normal backwash water pressure, combined cleaning (nitric acid + ultrasonic + backwash) time is sufficient, sufficient amount of nitric acid.
Q:What about the leakage of the ceramic filter static and dynamic sealing points?
The filtrate pump works to drain or recycle the water that has been pumped out. 6 、 cleaning system work, cleaning system includes backwashing (water pump pressure or height difference pressure), acid liquid (metering pump, automatic acid injection), ultrasonic (ultrasonic work), etc.. 7 、 control system and other electrical systems. In addition, the filter cake which is absorbed and dried on the ceramic filter plate is unloaded automatically by the scraper and then falls on the belt conveyor, and is conveyed to the concentrate storage yard by a belt conveyor. Other questions about ceramic filter, welcome to chat with me or look at my head
Q:The vacuum of ceramic filter is not enough
The vacuum degree of ceramic filter is about -0.08MPa, if the ceramic filter is less than 0.06MPa, the vacuum is not enough. If the vacuum of ceramic filter is not enough, it will influence the suction effect of ceramic filter (mainly the thickness of filter cake and water content of filter cake).
Q:Why should filter core be used in backwash of ceramic filter?
The filter in the water filter of ceramic filter is used for filtering water.
Q:The ceramic filter plate is broken. What will happen to the vacuum pump?
That's a good question. I hope my answer will help you.Ceramic filter ceramic plate broken, nothing more than ceramic plate plug and ceramic plate rupture, you should be the problem of ceramic plate rupture.
Q:What is the backwashing pressure of the ceramic filter?
It should be said that the ceramic filter backwash, usually with a certain pressure of clean water to backwash.
Q:Ceramic filter fineness thin mud suction is not what to do more
With ceramic filter to treat pulp dehydration, the particle size is too large, the particles are easy to precipitate, the particle size is too small, too much mud, then the water content of the filter cake will increase, and the life of the ceramic filter plate will be reduced.
Q:The use of water glass as beneficiation agent, copper concentrate in the ceramic filter can not filter, how to do?
Water glass is a kind of adhesive of flotation reagent, after use may cause the pulp viscosity increased, leading to the adsorption resistance of slurry becomes large, when using ceramic filter filtration dewatering, vacuum suction surface of the microporous ceramic filter plate is smaller than the resistance, there may be a suction effect or even not suction. Some flocculant agents can lead to this phenomenon.
