In general, under ideal conditions, the filter cake moisture of lead concentrate processed by ceramic filter is about 10%. The processing capacity of the ceramic filter is affected by the operating condition of the equipment itself and the external mining conditions, and the user should consider the problem comprehensively. I have answered similar questions before, please refer to, I hope it can help you:
Ceramic filter itself.
Ceramic filter depends on the vacuum suction on the ceramic filter plate to achieve the purpose of cake dehydration and drying, ceramic filter plate needs to be cleaned and has a life, if the user finds that the suction effect is poor or even does not suck, it should first consider these three aspects:
Ceramic filter plate
The two most likely factors of the ceramic filter plate are rupture and plugging: rupture will lead to vacuum distortion and poor cleaning; Plugging will lead to poor suction effect of the filter plate or even no suction, such as suspected ceramic filter plate plugging, you can moderately strengthen cleaning (such as shortening the cleaning cycle, extending the cleaning time, increasing the amount of nitric acid, etc.), such as strengthening the cleaning effect is still not improved, It should be considered that its life should be scrapped in time and replaced with a new ceramic filter plate (when replacing the new board, the new and old or different manufacturers of the board should not be installed on the same line, it is best to replace the whole set).
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 there will be poor suction effect or even no suction.
If the vacuum is abnormal, you should insist on whether the vacuum pump is faulty, whether the vacuum connection pipeline leaks water, how the sealing performance of the friction plate of the distribution valve is, whether the rubber pipe connected to the water outlet of the ceramic filter plate is aging or falling off, and whether the ceramic filter plate is broken.
cleaning
The cleaning of the ceramic filter is divided into two parts: backwash cleaning (also useful gas) and joint cleaning, the purpose of cleaning is to discharge the blocked particles from the ceramic filter plate.
Backwash water cleaning directly visual water filter after the water pressure can be, generally between 0.08-0.12mpa, if less than 0.05MPa, the washing effect is poor or even no washing effect, resulting in the accumulation of blockage and eventually lead to the ceramic filter plate plugging hole scrap. Timely replacement of the filter element and ensure the pre-filter water pressure can provide stable backwash water pressure.
Joint cleaning is the use of ultrasonic vibration, nitric acid dissolution and other methods to maximize the removal of backwashing can not be washed off the blockage, the general ceramic filter for each continuous 8 hours of work should stop cleaning for 1 hour, such as the use of old plates or poor suction effect, can moderately strengthen the cleaning (such as shortening the cleaning cycle, extending the cleaning time, increasing the amount of nitric acid, etc.).
Other reasons
If 1,2,3 are normal, but the filtrate can not be discharged normally, the spindle speed is too fast or even the ceramic filter itself manufacturing defects, the user's own modification of the equipment, etc., may lead to abnormal operation of the equipment.
We focus on ceramic filter plate for many years, welcome more exchanges.
external reason
Changes in feeding conditions: such as finer slurry size, higher mud content, thinner concentration, etc., and even improper operation may lead to. Users find that the fault cannot be solved by themselves should contact the manufacturer for help in time.
