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?

What filter bags is suitable for asphalt mixing stations for dust/fume collection? For keeping the road building works continuous, the asphalt temperature always kept at a higher side, so how to choose the filter bag for the asphalt concrete mixer is very crucial.

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.

The end users sometimes are confused on the air/cloth ratio design from the filter bag dust collector manufacturers, because the same operation condition offered to different dust collector manufacturers the air/cloth ratio may different,

Generally, the flue gas need to be filtered from thermal power plants which is mean the flue gas exhaust from their boilers (can be coal fired, oil fired, bio-mass fuel fired boilers and so on).

In the current economic situation, all industries around the world facing the big challenge that saving energy and reducing emissions, the cement industry as one of the main dust air sources always on the way to finding better filtration solutions, which is helpful for us to get a good environment, also can collect much cement dust and save much cost.
