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.
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.
Vacuum: about -0.08MPaIf the vacuum required to consider other factors; such as the vacuum degree is not up to even only about -0.05MPa, it should be related to pipeline inspection of vacuum system leakage, vacuum pump damage, distribution valve failure, ceramic plate breakage, ceramic plate connecting pipe leakage may cause the vacuum is not up to, to achieve early detection and early treatment.
