Ceramic Foam Filter for Alumina Making Industry

Composite of Ceramic Foam Filter for Alumina Making Industry

Ceramic Foam Filter is developed as a new type molten metal filters to decrease casting flaw in recent years. Foamed ceramics have the characters of light weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance and high temperature stability in molten metal. With the distributing pores net structure, they are able to increase the surface areas, and absorb the sinter, the liquid metal becomes more pure, waster quality problems such as sand pore and air pore are much less and the cast quality becomes much better.

Advantages of Ceramic Foam Filter for Alumina Making Industry:

Precise Dimension Tolerance

High Mechanical Strength

Chemical Stability and Corrosion-resistance for molten aluminum.

Phosphate-free, No Pollution for Environment

Purifying Liquid Aluminum, Improving Quality

Reduce Defects

Reduce Cost

Increase Yield Rate

Easy to Use

Size from 40-600mm available.

Q9:Can U accept the detective of the third-party verification company ?

A:YES! We can accept the detective from any third-party verification company including the SGS, BV and so on.

Q:Can the plate filter press pass through the filter plate?: There are many types of pumps to be used, such as screw pumps, slag pumps, rotary pumps, piston pumps, and diaphragm pumps.

Q:Can the ceramic plate filter the hot air?: The cleaning of the ceramic filter is divided into two parts: reverse flushing (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the particles from the hole to the ceramic filter board. Anti flushing and cleaning water filter after direct visual pressure can, generally between 0.08--0.12MPa, such as less than 0.05MPa, while the poor flushing effect without even washing effect, resulting in blocking accumulation eventually led to the ceramic filter plate hole plugging scrap. Replacing the filter element in time and ensuring the water pressure before filtration can provide stable backwashing water pressure. Combined cleaning by ultrasonic vibration, nitrate dissolution method for maximum remove blockage of backwash rushed out, the general ceramic filter every 8 hours of continuous work should stop cleaning 1 hours, such as the use of the old plate or the suction effect is poor, can strengthen cleaning (such as shorten the cleaning period, prolong the period of cleaning, increase the amount of nitric acid etc.). Other reasons such as 1,2,3 are normal, but can not be discharged from the spindle speed too fast, even the ceramic filter itself manufacturing defects, the user equipment modification and so on, are likely to lead to abnormal operation of equipment. We specialize in ceramic filter boards for many years and welcome exchanges.

Q:Ceramic filter cleaning, sulfuric acid cleaning: Ceramic filter medium is ceramic, ceramic generally resistant to strong acid, alkali, cleaning, it is best to use nitric acid, hydrochloric acid next, not recommended to use sulfuric acid.

Q:Common troubles of ceramic filter: Ultrasonic cleaning, ceramic filter plate cleaning is not clean. The main reason is that the power box is faulty, the power supply is burned out, the line is aging, the energy head is burned out, the ultrasonic box is broken down, and the water level in the pulp tank is too low;

Q:How much is the accuracy of 50nm ceramic membrane filtration?: 50nm refers to the nominal pore size, but it does not mean that the holes in the ceramic membrane are 50nm, but the approximate number of holes. The size of the pores may be between 40~60 and 45 to 55nm. Generally introduced, annotated range, you can also own to detect.

Q:What is the working pressure of the ceramic filter?: The backwash pressure is the size of the backwash of the ceramic filter during recoil stage, and the recoil pressure is generally less than 0.12MPa. The greater the pressure, the better the recoil effect, the better the service life and the suction effect of the ceramic filter plate, and the worse the service life and the suction effect of the ceramic filter board. The backwash pressure of the ceramic filter shall be no less than 0.07MPa.

Q:The ceramic filter plate is broken. What will happen to the vacuum pump?: If it is found that the ceramic plate is broken, it should stop in time to replace the broken ceramic plate. Ceramic filter is produced by vacuum suction vacuum pump to the pulp in the water through the ceramic plate away, the surface aperture ceramic plate for several microns, so it can intercept the cake on the ceramic plate on the surface, if the ceramic plate is broken, a hole is a few millimeters, when the vacuum suction pump when they go together along with the pulp pump.

Q:Performance advantages of ceramic filter: The base is provided with a slime recovery rotor, the rotor consists of a shaft, multistage ceramic filter disc, stripper plate, multi section water connecting pipe, pipe support plate, negative pressure connecting component dynamic disk; the rotor is in the recovery of coal slime liquid tank; the ceramic filter disc by a plurality of ceramic microporous plate cavity, located on the same axis of a ceramic plate cavity communicated through the outlet connection pipe.

Q:What is the filtration accuracy of 50nm ceramic membrane?: 50nm refers to the nominal pore size, but it does not mean that the holes in the ceramic membrane are 50nm, but the approximate number of holes. The size of the pores may be between 40~60 and 45 to 55nm. Generally introduced, annotated range, you can also own to detect.

Q:What are the reasons for the program alarm of ceramic filter?: If you say "lean" is the ceramic filter suction when the ceramic filter plate into a cake of thin, high water content, is the ceramic filter for their own reasons, can from the following aspects: the investigation considering this phenomenon is always so recently or just happened, if you have been so, probably because your selection is not suitable for pulp the ceramic filter (such as mud content, fine grain size, ceramic filter plate selection such as inconsistent or unqualified ceramic filter). If this anomaly has occurred recently, it is possible to change the ore condition, and the operation parameters of ceramic filters or the cleaning are not up to standard. You can check the vacuum system (vacuum generally ranges from -0.09 to -0.075MPa), backwashing system (generally refers to the filtered water recoil 0.07 ~ 0.12MPa), acid (HNO3 system standards), ultrasonic system is normal.
