Product Description:

Extruded ceramic filter

Application: Grey iron, ductile iron, aluminum alloy and other non-ferrous alloys.

NINGXIN ECF filter can effectively remove inclusions and eliminate turbulence in the metal stream. Mullite-based ceramic material with a dense network of perfectly cells to withstand thermal shock and extreme pouring temperatures.The cellular design also provides an engineered balance between flow rate and strength.Our extruded ceramic filters have excellent properties of good thermal stability, high specific surface area and resistance to acid and alkali. They are applicable to wide and extensive foundry filtration applications and processes.

Product features:
-Decrease the impurity of molten metal
-Deduce the turbulence of molten metal
-Improve the castings mechanical properties
-Decrease machining cost and improve the cutting characteristics
-Improve casting quality and yield

Q:Ceramic filter capacity.
60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.
Q:Does the ceramic factory use hydrochloric acid?
In order to avoid the possibility of plugging, ceramic filter plates with suitable aperture range of different manufacturers can be selected.
Q:Principle of chemical engineering drum vacuum filter, the faster the speed, the less the amount of filtrate obtained per turn, the more the amount of filtrate obtained per unit time?
The faster the speed is, the shorter the time required for each turn, i.e., the shorter the filtration time, the less the filtrate will be
Q:Microporous ceramic filter plate cleaning
Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.
Q:The vacuum degree of the ceramic filter is normal and the cake water is large?
The concentration, particle size and mud content of the raw materials are not suitable for or due to changes, which are no longer suitable for dehydration using ceramic filters
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:The vacuum degree of the ceramic filter is normal and the cake water is large
The concentration, particle size and mud content of the raw materials are not suitable for or due to changes, which are no longer suitable for dehydration using ceramic filters
Q:Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
The incoming mud content, fine particle size, pulp itself is not suitable for the use of ceramic filter dehydration, if the use of ceramic filter dehydration in this case, will accelerate the blockage of ceramic filter plate, blocking the situation after the second reference description.
Q:What is the backwashing pressure of the ceramic filter?
The working process of ceramic filter is: suction - drying - unloading - backwash - suction - drying - unloading - backwash...... In circulation, suction, the drying process is to make the slurry liquid by vacuum suction and capillary effect (usually water) through the filter media from the left, the filter cake on the filter medium (the two processes like syringe pumping), and then through the scraper discharge, after unloading, ceramic filter machine is complete a cycle in the absorption slurry, drying process, some fine particles may enter the filter medium or stacked on the surface (a lot of pipeline internal filtration medium ceramic filter plate), these small particles blockage will make the filter medium permeability and filtering effect of the loss from the poor, in order to reduce the possibility of blockage ceramic filter, will enter the backwash (this process is like a water jet injector). Ceramic filter backwash is through the pressure of water, these small particles plug discharge ceramic filter board.
Q:The use of water glass as beneficiation agent, copper concentrate in the ceramic filter can not filter, how to do?
Water glass is a kind of adhesive of flotation reagent, after use may cause the pulp viscosity increased, leading to the adsorption resistance of slurry becomes large, when using ceramic filter filtration dewatering, vacuum suction surface of the microporous ceramic filter plate is smaller than the resistance, there may be a suction effect or even not suction. Some flocculant agents can lead to this phenomenon.
