Product Description:

APPLICATION:For the filtration of molten aluminum and non ferrous alloy.

Alumina Ceramic Foam Filters mainly for filtration of aluminum and alloys in foundries and cast houses .With the excellent
resistance to attack and corrosion from molten aluminum, the filter can effectively remove inclusions, reduce trapped gas
and provide laminar flow and then the filtered metal is significantly cleaner.Cleaner metal results in higher-quality castings,
less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

-Reduce scrap related to inclusions.
-Reduce costs related to inclusion defects.
-Increase productivity with higher extrusion or rolling speeds.
-Increase casting flexibility with easy alloy changes.
-No holding metal.

*Superior dimensional tolerances
*Stable chemical composition
*Highest filtration efficiency
*Excellent strength
*Resistant to corrosion attack by molten aluminum and alloys
*Beveled edges and compressible gasket

Q:What is the reason that ceramic filter does not absorb mineral powder?
One is leakage, two is no liquid output or output weakness, pressure is too low, cleaning effect is not good, the pressure is too large, will cause damage to the filter plate and reduce the slurry concentration. The recoil pressure is regulated by the pump loop valve and the pressure regulating valve.
Q:Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
Beneficiation of ceramic filter, the technical parameters are normal, but the water will fill in groove is what reason
Q:What is the working pressure of the ceramic filter?
Vacuum pressure or suction is the vacuum of the equipment, the size of the vacuum directly affects the effect of ceramic filter board suction (yield and water content). The vacuum system of ceramic filter consists of vacuum pumps, tanks, distribution device, ceramic filter plate and a connecting pipe is composed of ceramic filter, the vacuum pump is generally 2BV series water circulation pump, the vacuum pump vacuum limit is -0.097MPa, using a vacuum pump for a long time or vacuum system has poor sealing performance may cause a certain degree of vacuum distortion, so the ceramic filter vacuum is generally difficult to achieve in the -0.097MPa, -0.08 ~ 0.097MPa, which indicates that the vacuum degree is good, such as the vacuum degree is not up to -0.07MPa or less, the vacuum system may be an exception.
Q:What are the materials that make up the ceramic mold?
At present, the commercialized porous ceramic membranes are mainly composed of 3 types: flat plate, tubular and multi channel. Flat film is mainly used for small-scale industrial production and laboratory research. The tubular membrane is combined with rice to form a heat exchanger similar to a column tube heat exchanger, which can increase the loading capacity of the membrane, but is gradually withdrawn from industrial application due to its strength problem. The size of the applied ceramic membrane usually adopts a multi channel configuration, that is, a plurality of channels are distributed on a circular cross-section, and the number of general channels is 7, 19 and 37. The main business of the inorganic ceramic membrane preparation technology: using solid particle sintering preparation carrier and microfiltration membrane by sol-gel method in the preparation of ultrafiltration membrane: glass membrane by phase separation method: using special technology (such as chemical vapor deposition, electroless plating, etc.) the preparation of microporous membrane or dense membrane. Its basic theory involves colloid and surface chemistry, material chemistry, solid state ion science, material processing and so on.
Q:What are the poor filtration effects of vacuum disc filters?
The spindle speed is slow, the formation time of growth in the area of vacuum filter cake, production capacity increased gradually, but because the unit time of grout thickness and spindle speed slow is proportional to, so the ceramic filter capacity in a range of showing the highest.On the other hand, as the spindle speed slows down, the thickness of the slurry is thickened, and the moisture of the concentrate is also affected. For viscous material, ceramic filter with ceramic plate to work as filter media, when the cake is formed gradually into the porous filter medium filter cake itself, and the cake is not easy to form a viscous material, forming a dry cake appearance does not slow, the spindle speed is easy to reduce the water content of concentrate. Similarly, the spindle speed is accelerated, the cake formation time in the vacuum zone is shortened, and the slurry thickness is reduced, and the material can be improved for the easy molding material. But the spindle speed is too fast to be cleaned after each cycle of the ceramic plate. As for the viscous material, the cake is difficult to form after the spindle speed increases, and it will affect the capacity. Therefore, the use of ceramic filter should focus on the inherent nature of the concentrate to explore the best spindle speed.
Q:The vacuum degree of the ceramic filter is normal and the cake water is large?
The vacuum degree of the ceramic filter is normal at about -0.08MPa. Under normal circumstances, the water content of the filter cake treated with a ceramic filter is about 10%, and the moisture content of the tail filter cake is about 15%. The water content of the filter cake increases with the increase of water content in the ceramic filter.
Q:Ceramic filter cleaning, sulfuric acid cleaning
Can be washed with chromic acid lotion. The effect is better
Q:What's the reason for high water content in filtration copper concentrate?
Can the cleaning of ceramic plate meet the requirement?Such as cleaning of ceramic plate is not up to the requirements, plugging holes will increase the risk of ceramic plate, ceramic plate plug serious suction effect will become worse (filter cake moisture content increased, cake thickness reduction), cleaning of ceramic plate refers to washing and cleaning.Backwash to ensure that the water filter filter water pressure in the 0.1MPa or so, at least not less than 0.07MPa or less, it is necessary to consider before the filter water pressure is low or water filter element needs to be replaced.Joint cleaning to ensure that the ultrasonic can be no trouble, every time cleaning the amount of nitric acid up to standard. If the filtration effect is not ideal, the cleaning cycle can be washed from 45--60 every 8 hours, changed to 6--7 hours and cleaned for more than 1 hours.
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 use of water glass as beneficiation agent, copper concentrate in the ceramic filter can not filter, how to do?
Of course, there may be equipment operating parameters can not meet the requirements, ceramic filter board has blocked hole close to scrap.Ceramic filter in use in the process of problems, should promptly contact manufacturers, seek help.
