The performance is not good. It is equivalent to the low-frequency version of the third generation desktop version (desktop) i5. The following figure is the official parameter screenshot (part). The 2013 model has four cores and four threads. Zhiqiang V2 is the second generation of Zhiqiang. It is the same generation as core III, and the frequency is only 2.5. It is not suitable to run the current popular games< br />
1. The relationship between pulp concentration change and ceramic machine output
1. The relationship between ceramic machine output and feed concentration is approximately parabolic. In general, the higher the feed concentration is, the greater the ceramic machine output is (but the water content of filter cake also increases slightly)
2. When the feed concentration is too high or the feed volume is too large (for example, the pulp concentration increases from 40% to more than 60%, and the supply exceeds the demand), the spindle speed and mixing speed can be adjusted quickly. At this time, the proction capacity of the ceramic machine may change from 40 t / h to 50 t / h. Although the proction is increased, the remaining slurry that cannot be adsorbed may flow out, and at the same time, There may be (large) particles deposited in the tank of the ceramic machine, causing deformation of the mixing device and vibration of the worktable. In this case, it is recommended to replace a new ceramic filter plate or add a new ceramic filter
Second, the influence of mud content on the filtering effect of ceramic filter
the more mud content, the worse the filtering effect of ceramic filter
the working part (filter medium) of the ceramic machine is the ceramic filter plate. The surface micropores (i.e. filtration precision) of the ceramic filter plate are generally several microns. The equipment needs to be cleaned (backwashing, nitric acid, ultrasonic) for about 1 hour after 8 hours of continuous operation. The particle size of sludge is smaller and easier to enter into the ceramic plate, and nitric acid has no effect on it. Therefore, the increase of mud content is more likely to block the ceramic plate, which not only affects the normal service life of the ceramic plate, but also affects the output of the ceramic filter

Due to the differences in the properties of the same material in various regions, the actual yield and moisture are subject to the test data
for example, when the feed concentration of iron concentrate is 60%, the output is 920kg / m2. H and the moisture content of filter cake is 9%
Description: if the size of iron concentrate pulp is - 200 mesh, accounting for 52%, when the feed concentration is 60%, the ceramic filter can proce 920kg concentrate per square meter per hour, and the water content of filter cake is 9%. Under this condition, if the equipment selection is 60 m2, the output of 60 M2 ceramic filter treating this kind of pulp per hour is 920 × 60 = 55200kg / set. H
There are many reasons for the increase of water content in filter cake of ceramic filter, as follows:
-
pulp characteristics: such as fine particle size and high mud content of treated minerals
-
change of ore feeding conditions: pulp concentration suddenly increases and mud content increases
-
Vacuum distortion: the vacuum system leaks, and the vacuum degree cannot reach the normal range
-
ceramic filter plate: the ceramic filter plate is damaged and leaking
-
cleaning: backwashing or combined cleaning is not up to standard
-
spindle running: the spindle speed is adjusted fast
-
clogging: ceramic filter plate is seriously blocked

other questions about ceramic filter are welcome to chat with me or see my picture
I don't know if "thin material" means that the concentration of slurry in the tank of ceramic filter is thin, or the slurry absorption cake of ceramic filter plate is thin and the water content is high
if it means that the slurry concentration in the tank of the ceramic filter is thin, it has nothing to do with the ceramic filter itself. We can find a way to increase the slurry concentration before entering the tank of the ceramic filter, so as to improve the dehydration efficiency of the ceramic filter
if what you mean by "thin material" is that the ceramic filter plate is thin and has high water content when the ceramic filter sucks slurry, then it is the reason of the ceramic filter itself, which can be considered from the following aspects:
< UL >is this always the case or just happened recently? If it has always been the case, it may be because the slurry selected by your company is not suitable for the ceramic filter (such as high mud content, low water content, high water content) The particle size is small, the ceramic filter plate selection is not consistent, etc.) or the ceramic filter is not qualified
if there is such abnormality in the near future, it may be e to the change of feeding conditions, the operation parameters of ceramic filter or the failure of cleaning. It can check whether the vacuum system (the general range of vacuum degree is - 0.09 ～ - 0.075mpa), backwashing system (generally refers to the backwashing water pressure after filtration is 0.07 ～ 0.12mpa), pickling system (the amount of nitric acid needs to reach the standard) and ultrasonic system are normal
the vacuum failure may be vacuum pump failure, vacuum pipeline leakage, ceramic filter plate rupture or connection leakage, and the backwashing system is generally lack of water pressure before filtration, filter element blockage, etc
insufficient vacuum will lead to poor pulp suction effect or even no pulp suction; If the cleaning is not up to the standard, the clogging of ceramic filter plate will be accelerated. Even if the vacuum of the clogged ceramic filter plate is normal, the slurry absorption effect will be poor or even not, such as thin cake and high water content
ceramic filter plate plugging scrap
the ceramic filter plate has a service life of about one year under normal circumstances. If the pulp contains a large amount of mud, fine particle size or contains components that are easy to precipitate, and the cleaning is not up to standard, its service life will be reced. When the ceramic filter plate is close to scrap, its slurry absorption effect will become worse
I hope my answer can help youGenerally speaking, under ideal condition, the moisture content of filter cake treated by ceramic filter is about 10%. The processing capacity of ceramic filter is affected by the operation status of the equipment itself and the external ore feeding conditions. The problems found by users should be comprehensively considered and analyzed. If you have answered similar questions before, please refer to them, hoping to help you:
< UL >ceramic filter's own reasons
the ceramic filter is dehydrated and dried by vacuum suction acting on the ceramic filter plate. The ceramic filter plate needs to be cleaned and has a long life. If the user finds that the slurry absorption effect is poor or even does not absorb slurry, he should first consider these three aspects:
-
ceramic filter plate
ceramic filter plate is the most likely two factors, They are rupture and hole plugging: rupture will lead to vacuum distortion and poor cleaning; If it is suspected that the ceramic filter plate is blocked, the cleaning can be strengthened moderately (such as shortening the cleaning cycle, prolonging the cleaning time, increasing the amount of nitric acid, etc.). If the effect is still not improved after strengthening the cleaning, it is necessary to strengthen the cleaning, It should be considered that its service life is approaching, and it should be scrapped in time and replaced with a new ceramic filter plate (when replacing the new plate, it is better to replace the old and new plates or plates from different manufacturers on the same line)
-
vacuum system failure
the vacuum degree of ceramic filter is generally about -0.085mpa. If the vacuum is abnormal, it can not provide normal vacuum suction, and the slurry suction effect is poor or even not
in case of abnormal vacuum, we should insist on whether the vacuum pump is faulty, whether the vacuum connecting pipe is leaking, how the friction plate sealing performance of the distribution valve is, whether the rubber pipe connecting the outlet of the ceramic filter plate is aging or falling off, whether the ceramic filter plate is broken, etc
-
cleaning
the cleaning of ceramic filter is divided into two parts: backwash water cleaning (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the blocked particles out of the ceramic filter plate
the backwash water can be cleaned directly by visual inspection of the water pressure after filtering of the water filter, which is generally between 0.08-0.12mpa. If it is lower than 0.05Mpa, the flushing effect is poor or even has no flushing effect, resulting in the accumulation of blockage and eventually the scrapping of the ceramic filter plate. The stable backwashing water pressure can be provided by changing the filter element in time and ensuring the pre filtration water pressure
combined cleaning is to use ultrasonic vibration, nitric acid dissolution and other methods to remove the blockage that can not be removed by backwashing to the maximum extent. Generally, ceramic filtration should be shut down for cleaning for 1 hour every 8 hours of continuous operation. If the old plate is used or the slurry absorption effect is poor, the cleaning can be moderately strengthened (such as shortening the cleaning cycle, extending the cleaning time, increasing the amount of nitric acid, etc.)
Other reasons such as 1, 2 and 3 are normal, but the filtrate can not be discharged normally, the spindle speed is too fast, even the ceramic filter itself manufacturing defects, the user's own modification of the equipment, etc., may lead to abnormal operation of the equipmentwe focus on ceramic filter board for many years, welcome more exchanges

external reasons
the change of ore feeding conditions, such as the slime size becoming smaller, the mud content increasing, the concentration becoming thinner, and even improper operation, may lead to the change of ore feeding conditions. If the user finds that the fault cannot be solved by himself, he should contact the manufacturer in time for help
