Product Description:

APPLICATION:For the filtration of molten aluminum and non ferrous alloy.

Alumina Ceramic Foam Filters mainly for filtration of aluminum and alloys in foundries and cast houses .With the excellent
resistance to attack and corrosion from molten aluminum, the filter can effectively remove inclusions, reduce trapped gas
and provide laminar flow and then the filtered metal is significantly cleaner.Cleaner metal results in higher-quality castings,
less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

-Reduce scrap related to inclusions.
-Reduce costs related to inclusion defects.
-Increase productivity with higher extrusion or rolling speeds.
-Increase casting flexibility with easy alloy changes.
-No holding metal.

FEATURES:
*Superior dimensional tolerances
*Stable chemical composition
*Highest filtration efficiency
*Excellent strength
*Resistant to corrosion attack by molten aluminum and alloys
*Beveled edges and compressible gasket

Q:What is the reason that ceramic filter does not absorb mineral powder?
One is leakage, two is no liquid output or output weakness, pressure is too low, cleaning effect is not good, the pressure is too large, will cause damage to the filter plate and reduce the slurry concentration. The recoil pressure is regulated by the pump loop valve and the pressure regulating valve.
Q:The ceramic filter suddenly did not smoke, and later he was all right. What's the reason?
How old the general ceramic filter suction main reason mud cake thickness is not much of a ceramic filter plate is different, because the ceramic filter backwash water, vacuum suction and nitrate are through the distribution valve, are often the same boat". See your description, you do not know the 5 line is about "5 disc or sideways 5 rows of ceramic plates, that is completely not suction or suction effect is poor, I hope to help you:
Q:Ceramic filter fineness thin mud suction is not what to do more
Users such as pulp size is too small, too much mud, after analysis, the following methods of testing, the results have improved, it may wish to try the following methods, perhaps of help:The vacuum degree is about -0.08MPa.Adjust spindle speed and increase drying time.Ceramic filter plate with suitable pore size range.Ceramic filter plate brand on the market range, its quality is good or bad, the feed condition itself is not an ideal situation, such as ceramic filter plate with the aperture to the mine conditions do not match, it will exacerbate the effects of poor, life is short.It can shorten the combined cleaning cycle, strengthen the cleaning effect and prolong the cleaning time.
Q:Common troubles of ceramic filter
(1) low vacuum, can not meet the production requirements. The main reason is the vacuum pipeline leakage, vacuum pump circulating water is not enough, vacuum pump impeller wear and tear, distribution head wear, ceramic filter plate damage, filtrate tank drainage valve is not closed, pulp trough material level is lower;(2) low or fluctuating backwash water pressure. The main reason is the blockage or leakage of the backwash water pipe system and the distribution of head wear;(3) the liquid level of the filtrate tank is high. The main reason is that the circulating water pump impeller or pump shell wear, pressure is insufficient, so that the drain valve can not open or drain valve itself failure, and filter barrels and circulating water pipe between the leakage;
Q:How can I avoid the backwash pressure in the production of ceramic filter?
The backwashing system of ceramic filter is usually made up of water inlet, water inlet, pressure gauge, water filter and filtered water pressure gauge, and then connected to the inside of ceramic filter. Such as the discovery of ceramic filter recoil pressure became smaller or even no recoil pressure, you can carefully observe the surface of the ceramic filter plate is wet or ceramic filter plate wear without water injection at the discharge point, investigation and the reasons for the following aspects:Is the water inlet pressure or normal?How about the sealing performance of the water filter? Does the filter element need to be replaced?Is the recoil system piping (metal pipe, ceramic filter plate, connecting pipe, etc.) broken, leaking or dripping?Is the distributor valve properly installed and is it worn?Are there any cracks in the ceramic filter plate?Is the pressure gauge broken?The most likely reason is 1, 2, two, the best water should not be too dirty, filter should be replaced regularly. I hope the answer can help you.
Q:What about the leakage of the ceramic filter static and dynamic sealing points?
The filtrate pump works to drain or recycle the water that has been pumped out. 6 、 cleaning system work, cleaning system includes backwashing (water pump pressure or height difference pressure), acid liquid (metering pump, automatic acid injection), ultrasonic (ultrasonic work), etc.. 7 、 control system and other electrical systems. In addition, the filter cake which is absorbed and dried on the ceramic filter plate is unloaded automatically by the scraper and then falls on the belt conveyor, and is conveyed to the concentrate storage yard by a belt conveyor. Other questions about ceramic filter, welcome to chat with me or look at my head
Q:How should the static and dynamic sealing points of the ceramic filter be leaking?
When the ceramic filter works, the operation may be as follows: 1. The feed is injected and the pulp is injected into the tank of the ceramic filter. 2, mixing system, ceramic filter stirring rake back and forth mixing, driven by mixing reducer. 3, spindle rotation, material level reached a certain range, through the spindle speed machine to drive the ceramic filter disk rotation.
Q:Does the ceramic factory use hydrochloric acid?
Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.
Q:What are the functions of honeycomb ceramic filters?
High quality and high density straight hole mesh, the product has high heat resistance and impact resistance properties of cast high fever temperature, design straight hole to guarantee the balance between strength and flow, effectively remove impurities and slag particles, the mechanical properties of casting, the surface quality and the qualified rate of products is greatly improved.
Q:Can the plate filter press pass through the filter plate?
There are many types of pumps to be used, such as screw pumps, slag pumps, rotary pumps, piston pumps, and diaphragm pumps.
