Q:How should the static and dynamic sealing points of the ceramic filter be leaking?
When the main shaft is rotated, the filter cake is adsorbed on the surface of the ceramic filter plate and dehydrated by the vacuum generated by the vacuum pump.
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:Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems
Equipment comes with cleaning:Ceramic filter comes with a combined cleaning system, usually to ensure the normal backwash water pressure, combined cleaning (nitric acid + ultrasonic + backwash) time is sufficient, sufficient amount of nitric 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:What are the causes of the powder moisture in the ceramic filter?
The ore condition has changed, such as high concentration of material, fine grain size and increase of mud content.
Q:Why does not the iron filter of the ceramic filter work?
The ore condition has changed, such as high concentration of material, fine grain size and increase of mud content.
Q:Ceramic filter cleaning, sulfuric acid cleaning
Can be washed with chromic acid lotion. The effect is better
Q:Is the filter plate of the ceramic filter afraid of freezing?
The ceramic filter plate by table and the distribution of a large number of porous capillary ceramic filter, when working in the water slurry channel is used so the microporous ceramic filter plate internal residual has a lot of water, such as low temperature, the inside of the frozen water volume will swell, causing damage to the ceramic the inside of the microporous filter plate structure.
Q:Performance advantages of ceramic filter
The base is provided with a slime recovery rotor, the rotor consists of a shaft, multistage ceramic filter disc, stripper plate, multi section water connecting pipe, pipe support plate, negative pressure connecting component dynamic disk; the rotor is in the recovery of coal slime liquid tank; the ceramic filter disc by a plurality of ceramic microporous plate cavity, located on the same axis of a ceramic plate cavity communicated through the outlet connection pipe.
Q:How many degrees does the ceramic filter melt?
Alumina made from tabular corundum can be used over 1800 degrees!SiC if there is atmosphere, protection will be higher, there is no atmosphere protection, because the existence of oxidation, generally not more than 1600.Corundum, mullite, 1750 degrees small meaning.
