- Q: What are the causes of the powder moisture in the ceramic filter?
- Generally, the ceramic filter is used to filter iron powder, and the water content of the filter cake is about 10%.
- 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: What's the reason for high water content in filtration copper concentrate?
- Ceramic filter plate1) the service life of the ceramic filter plate has arrived.2), ceramic filter plate uneven in quality on the market, the production capacity of some ceramic products difference (table mask size is too large or pore size uniformity is poor as a result of suction effect is poor, short life), but the price is low, but some users in order to reduce the operation cost of ceramic machine, tend to choose low price the ceramic plate, sometimes a ceramic machine ceramic filter plate with several may be different, so do not get the expected effect in normal use.In addition, the concentrator slurry, especially metal slurry, is very powerful on the wear of ceramic filter plate, the mechanical strength and wear resistance of ceramic filter plate requirements (corundum has high mechanical strength, good abrasion resistance, especially suitable for metal slurry dehydration).When selecting ceramic filter boards, these two points should be taken as a reference.
- 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.
- 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: How much is the accuracy of 50nm ceramic membrane filtration?
- It should be noted that due to wear, plugging and so on, the new and different degrees of ceramic film, the pore size will change. Micron scale ceramic membrane filtration accuracy is very good, nano scale aperture range of such a small ceramic film does not know in what way.
- Q: What is the reason that the ceramic filter does not absorb mineral powder?
- The recoil pressure is regulated by the pump loop valve and the pressure regulating valve. In order to avoid frequent fluctuations in pressure and pressure within a short period of time, a buffer cylinder with a stabilizing effect is provided in the backwash pipe.
- Q: How can I avoid the backwash pressure in the production of ceramic filter?
- Recoil of the ceramic filter is on the clean water under certain pressure, from the inside out flushing blockage blockage in the ceramic filter plate on the internal pore water pressure, the recoil is generally less than 0.12MPa, the pressure is too small or no recoil recoil effect is not good.
- 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: What are the functions of honeycomb ceramic filters?
- High quality and high density straight hole mesh, the product has high heat resistance and impact resistance properties of cast high fever temperature, design straight hole to guarantee the balance between strength and flow, effectively remove impurities and slag particles, the mechanical properties of casting, the surface quality and the qualified rate of products is greatly improved.
