The air slide chute conveying system is an extreme form of airtight pneumatic conveying method, which uses low-pressure air to pass through the air slide fabrics to achieve the purpose of powder/particle conveying.
The compressed air disperses after passing through the air slide fabric and enters around the particles, which overcomes the resistance of the particles and air slide fabrics, so that the particles become to fluidization conditions like liquid, then flows by gravity in the tank.
Compared with some mechanical conveying systems, the air slide chute system with the properties of no rotating parts, no noise, convenient operation and management, light equipment weight, low energy consumption, simple structure, large conveying capacity, and easy to change the conveying direction. Very economical equipment for conveying powdery materials and granular bulk solids.

As the dust collection technology develops, more and more dust collecting methods are invented and improved, because of the advantages of high filter efficiency and stable lower dust emission, the bag style dust filters are the most popular dust filters nowadays, and the pulse jet bag filter house is the most popular bag filters due to the broad adaptability.

The reasons to choose the fiber glass filter bag with PTFE membrane treatment:
the high tensile strength:
The tensile strength of the fiber glass filter fabric is more than 4000N/50mm as usual, which is much higher than chemical fiber filter materials and the blended filter materials, which is very suitable for the long filter bags sewing.
Anti-corrosion
Fiber glass filter bag can keep a good performance in the circumstance of acid and alkali (except hydrofluoric acid and strong phosphoric acid).

The properties of the filter cloth with PTFE membrane laminated.
better filter efficiency
The PTFE membrane with a cross micro open size can filter very tiny dust (fume), especially good for ultra-fine dust collection, and lower emission.
lower resistance
The filter cloth with PTFE membrane which collects the dust is a kind of surface filtration, the surface is smooth which is very good for bag purging works, so it’s not easy to block or even filter the ultra-tiny dust and wet dust, so the average resistance is lower when compared to the normal filter materials.

The air pollutants from cement production and the relevant solutions.
The air pollutants from cement production mainly are dust and flue gas.
The dust mainly comes from the following procedures:
1. the raw materials preparation
A.CaCO3 crush.
B.Clay drying
C.Coal grinding and feeding.
D. Raw meals grinding.

Why some filter bags/ filter cartridges need water and oil repellent treatment?
We always receive questions from the end users of the dust collectors as that why the filter bags/filter cartridges need to make the finish treatment of water oil repellent.
The answer is that for some filtration circumstances, this treatment will improve the performance and prolong the service life of the dust filter bags/dust filter cartridges.
Generally speaking, following situation we consider it easy to dewing:

How to choose a suitable cartridge dust collector?
As usual, for choosing a suitable cartridge dust collector, we need the following information:
the dust air content information:
A. For what kind of processing? Such as polishing dust collection, welding fume removal, break mills dust filter, etc.
B. What’s the solid particle material? Such as steel powder, copper powder, aluminum powder, welding fume, fiber glass powder, sugar powder, etc.
C. What’s the size of the particles (microns)?
D. How many grams of the solid particles in dust air per CBM?
E. Any corrosive material included?

During routine maintenance of bag filters, problems of varying severity inevitably arise. As the filter bags are the core component of the system, their condition directly impacts the overall filtration performance. We have listed some typical problems encountered with filter bags below. If you experience any issues with your filter bags, please do not hesitate to contact Zonel Filtech; we will provide you with professional solutions!

As we know, to choose the suitable filter fabrics, we have to combine the solution data together with filter fabrics.
If the density of the filter cloth is too high, which may cause the output less and affect the capacity of the filter press, that may lead to not getting the filter cake with a certain moisture content at a certain time, some even can not get the cake and always be slurry state.
