APPEARANCE REQUIREMENTS:
-No cracking allowed across the full length of the edge
-Any fine cracks within the filter matrix may not be through-going
-Filters should be free from loose debris
- Q: Is the filter plate of the ceramic filter afraid of freezing?
- The filter plate of ceramic filter is afraid of frost and should be protected.
- Q: Influence factors of ceramic filter
- 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. Generally, the higher the temperature, the smaller the viscosity of the liquid, the more conducive to improve the filtration rate, reduce the cake or sediment water, while reducing the viscosity of the slurry, can improve the processing capacity.
- 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: Ceramic filter fineness thin mud suction is not what to do more
- Users such as pulp size is too small, too much mud, after analysis, the following methods of testing, the results have improved, it may wish to try the following methods, perhaps of help:The vacuum degree is about -0.08MPa.Adjust spindle speed and increase drying time.Ceramic filter plate with suitable pore size range.Ceramic filter plate brand on the market range, its quality is good or bad, the feed condition itself is not an ideal situation, such as ceramic filter plate with the aperture to the mine conditions do not match, it will exacerbate the effects of poor, life is short.It can shorten the combined cleaning cycle, strengthen the cleaning effect and prolong the cleaning time.
- Q: Microporous ceramic filter plate cleaning
- For the use of a long time, the method 1, the effect is still no significant improvement, that is how to plug the ceramic filter plate regeneration? The ceramic filter plate with uneven or non sucking slurry can be removed, and oxalic acid or other acid liquid with certain concentration and certain temperature can be taken together to dredge the microporous of the ceramic filter plate. (do not recommend sulphuric acid)
- Q: What is the reason that the ceramic filter does not absorb mineral powder?
- There may be a fault filtrate pump, diaphragm pump damage, pump mechanical seal failure, a leak, two is no output or output to the liquid, the pressure is too low, the cleaning effect is not good, the pressure is too large, will cause damage and reduce the concentration of slurry filter plate.
- 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: Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems
- Oxalic acid immersion:For the use of a long time, the method 1, the effect is still no significant improvement, that is how to plug the ceramic filter plate regeneration? The ceramic filter plate with uneven or non sucking slurry can be removed, and oxalic acid or other acid liquid with certain concentration and certain temperature can be taken together to dredge the microporous of the ceramic filter plate.
- Q: Excuse me, what's the reason that all ceramic filters do not attract ore?
- Whether the ore conditions are changed, such as pulp type, mud content, fineness, concentration, etc..
- Q: What is the backwashing pressure of the ceramic filter?
- Ceramic filter is a kind of solid-liquid separation, dehydration drying equipment, such as dehydration pulp, mortar. The backwash of ceramic filter is to flush the filter medium (ceramic filter plate) with clean water with a certain pressure.
