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: The ultrasonic wave of ceramic filter is not good. What's going on?
- The earliest filtration was mostly gravity filtration, which was followed by pressure filtration to increase the rate of filtration, followed by vacuum filtration. The drum vacuum filter invented in the early twentieth Century realized the continuous operation of the filter. Since then, various types of continuous filters have appeared. Intermittent operating filters (such as plate and frame press filters) are developed for automatic operation, and the filtration area is becoming larger and larger. In order to obtain the filter residue with low moisture content, the mechanical press filter has been developed.
- Q: How many degrees does the ceramic filter melt?
- You should say clearly what ceramic you useHowever, as a melting furnace or filter medium, alumina products are the most versatile, but also silicon carbide, corundum, mullite, spinel and so on. They use very high temperatures.
- Q: What's the reason for high water content in filtration copper concentrate?
- Can the cleaning of ceramic plate meet the requirement?Such as cleaning of ceramic plate is not up to the requirements, plugging holes will increase the risk of ceramic plate, ceramic plate plug serious suction effect will become worse (filter cake moisture content increased, cake thickness reduction), cleaning of ceramic plate refers to washing and cleaning.Backwash to ensure that the water filter filter water pressure in the 0.1MPa or so, at least not less than 0.07MPa or less, it is necessary to consider before the filter water pressure is low or water filter element needs to be replaced.Joint cleaning to ensure that the ultrasonic can be no trouble, every time cleaning the amount of nitric acid up to standard. If the filtration effect is not ideal, the cleaning cycle can be washed from 45--60 every 8 hours, changed to 6--7 hours and cleaned for more than 1 hours.
- Q: The use of water glass as beneficiation agent, copper concentrate in the ceramic filter can not filter, how to do?
- As everyone knows, ceramic filter medium is a ceramic filter plate, microporous ceramic filter plate with a lot of distribution from the outside to the inside capillary effect, its mechanism is based on the capillary effect of microporous ceramic filter, filtration, the filtrate (generally refers to water) through these pores under the action of the vacuum suction pump, filter cake is trapped on the surface of the ceramic filter plate.
- Q: The vacuum degree of the ceramic filter is normal and the cake water is large
- The concentration, particle size and mud content of the raw materials are not suitable for or due to changes, which are no longer suitable for dehydration using ceramic filters
- 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: 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: Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems
- Selection of new ceramic filter plate:Because of the different size and characteristics of the pulp, different users need ceramic filter plates with different pore sizes (i.e., the average range of their surface pore size). In order to avoid the possibility of plugging, ceramic filter plates with suitable aperture range of different manufacturers can be selected.
- Q: What's the acid of the ceramic filter plate?
- General ceramic filter running for eight hours or so, you need to stop for joint cleaning, general cleaning at an hour or so. When washing together, there is acid washing, usually concentrated nitric acid. The purpose is to dissolve the pores in the ceramic filter plate through nitric acid.
- Q: Ceramic filter suddenly do not smoke, a little later on their own good, what reason?
- The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.
