1.Production of ceramic foam filter
Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.
2. Functions of ceramic foam filter
1). Thermal and chemical stability in high temperature,avoiding the chemical reaction with the filtered molten metal;
2). High porosity and good mechanical strength in high temperature due to its pure ceramic composite;
3). Low head loss,easy operation,energy-saving;
4). Making metal liquid flowing at stable speed and avoiding the sputtering and backset,thus increasing the surface quality of the cast part,preventing the pore disfigurement and finally lower down the unqualified rate;
5). Various sizes,shapes,apertures are available for kinds of foundry technique.

- Q: Working principle, ultrasonic trouble and troubleshooting of ceramic filter
- The shape and mechanism of the ceramic filter are similar to those of the disc vacuum filter, but the filter media are different. The filter medium of ceramic filter is the ceramic filter plate, it can produce the micro capillary effect and capillary force in micropores is higher than the general vacuum applied force, so that the pores keep full of liquid state, so no matter what the circumstances, the air does not pass through the ceramic filter plate, so that the ceramic filter solid-liquid separation of low energy consumption, and high vacuum.
- Q: What's the reason for high water content in filtration copper concentrate?
- Vacuum: about -0.08MPaIf the vacuum required to consider other factors; such as the vacuum degree is not up to even only about -0.05MPa, it should be related to pipeline inspection of vacuum system leakage, vacuum pump damage, distribution valve failure, ceramic plate breakage, ceramic plate connecting pipe leakage may cause the vacuum is not up to, to achieve early detection and early treatment.
- Q: Can the plate filter press pass through the filter plate?
- Specific, it is necessary to choose the filter characteristics according to different materials. Plate and frame filter press: plate and frame filter press is an industrial realization of solid, liquid separation, plate and frame filter press is suspension, liquid-solid, liquid two phase, applied to chemical, ceramics, oil
- Q: Common troubles of ceramic filter
- (1) low vacuum, can not meet the production requirements. The main reason is the vacuum pipeline leakage, vacuum pump circulating water is not enough, vacuum pump impeller wear and tear, distribution head wear, ceramic filter plate damage, filtrate tank drainage valve is not closed, pulp trough material level is lower;(2) low or fluctuating backwash water pressure. The main reason is the blockage or leakage of the backwash water pipe system and the distribution of head wear;(3) the liquid level of the filtrate tank is high. The main reason is that the circulating water pump impeller or pump shell wear, pressure is insufficient, so that the drain valve can not open or drain valve itself failure, and filter barrels and circulating water pipe between the leakage;
- Q: Ceramic filter capacity.
- You ask too general, to say processing capacity (ie capacity), at least to provide material conditions, such as: material name, concentration, particle size distribution. In addition, the basic conditions of equipment operation should be taken into account.
- 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: The vacuum of ceramic filter is not enough
- Maybe the vacuum meter is broken. It doesn't show or show the data is different from the actual data.It could be the source of the vacuum, the vacuum pump failure.Pipeline leakage: vacuum system connecting pipes (metal pipes or rubber pipes) corrosion, aging and water leakage.Distributor head leakage: wear or poor sealing.Leakage of ceramic plate: rupture of ceramic plate.Other reasons.
- 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.
- Q: Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
- First, the fineness of the material, resulting in the filter board filter cake moistureTwo, the vacuum can not reach, in the circumstances, whether the vacuum pipe leak
- Q: What is the reason that the whole ceramic filter does not attract ore?
- Vacuum system failure, no vacuum or vacuum can not meet the requirements. Should check the vacuum pump and vacuum piping, distribution head, ceramic plate, such as failure or leakage.Whether the ore conditions are changed, such as pulp type, mud content, fineness, concentration, etc..
