1.Product Description of ceramic foam filter
Ceramic foam filter is a kind of effective molten metal filter. It’s three-dimensional connected mesh skeleton structure and high porosity makes it has many advantages,large surface area of slags collection,large inner surface area of filtering,Small flow resistance,good filtering effect,etc.
2. Functions of ceramic foam filter
decontaminate the melting metal liquid,Simplified gating system
Improve the metallurgical structure of the castings,Reduce imparities of the castings
Improve casting quality rate,Reduce casting internal re-oxidation defects
Reduce the surface defects after machining of the castings

- 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 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..
- 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: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's the acid of the ceramic filter plate?
- Ceramic filter automatic control system: control system through the metering pump will be concentrated nitric acid automatic mixing ceramic filter plate into nitrate after proportioning through the pipeline, so that it can be dissolved, dredge the blockage in the most microporous ceramic filter plate. This is the ceramic filter plate pickling, pickling, acid dosage should be sufficient as little pickling effect.
- Q:Ceramic filter cleaning, sulfuric acid cleaning
- Can be washed with chromic acid lotion. The effect is better
- Q:What is the working pressure of the ceramic filter?
- Generally speaking, there are two kinds of working pressure of ceramic filter: vacuum pressure and reverse flushing pressure.
- Q:The ceramic filter suddenly did not smoke, and later he was all right. What's the reason?
- How old the general ceramic filter suction main reason mud cake thickness is not much of a ceramic filter plate is different, because the ceramic filter backwash water, vacuum suction and nitrate are through the distribution valve, are often the same boat". See your description, you do not know the 5 line is about "5 disc or sideways 5 rows of ceramic plates, that is completely not suction or suction effect is poor, I hope to help you:
- Q:The working principle of ceramic filter
- Based on the work principle of ceramic filter function of the capillary, by using porous ceramic as filter media, a large number of small capillary action with solid-liquid separation equipment design principle using microporous ceramic disc filter in negative pressure, working conditions, characteristics of the microporous ceramic filter plate with its unique water impermeable, extraction of ceramic filter plate and external vacuum cavity the differential pressure tank suspension material under the action of negative pressure adsorption in the ceramic filter plate, solid material can not through the microporous ceramic filter plate is retained on the surface of the ceramic plate, and the liquid due to the hydrophilic effect of vacuum pressure difference and the ceramic filter plate is passed into the gas-liquid distribution device (vacuum barrel) efflux or recycling so as to achieve the purpose of solid-liquid separation.
- Q:How to determine the quality of ceramic fiber filter board simply?
- Ceramic fiber filter board, in fact, ceramic fiber board, also known as aluminum silicate, refractory fiberboard.
