What are the requirements for selecting filter fabric bags in cement factories?

Firstly, high-temperature resistant filter bags

During the cement production process, the temperature is very high, and it is necessary to choose high-temperature resistant filter bags. Generally speaking, the high-temperature resistance of filter fabric bags is related to the temperature of the place of use. According to data, under normal circumstances, the temperature during cement production is approximately 150 ℃ -200 ℃. Therefore, it is necessary to choose the best filtering material to ensure that the filter bag can withstand the high temperature environment that has been present throughout the cement production process.

Secondly, higher filtration efficiency

The dust collection equipment mainly filters the dust generated during the cement production process through filter bags, so the filter fabric bags in cement plants need to have excellent filtering performance. In the cement production process, dust particles are often very small, and it is necessary to choose filter bags with small pore sizes and strong filtering ability to ensure the filtration efficiency of dust particles.

Thirdly, corrosion-resistant filter bags

In the process of cement production, dust is often accompanied by harmful gases such as SO2 and Cl2, which can corrode and damage the filter bag. Therefore, in the cement production process, cement factories need to choose dust collection filter bags with good corrosion resistance to ensure their long-term stable operation.

Fourth, high strength and wear resistance

Due to the presence of high hardness substances such as stress and basalt in the dust particles generated during the cement production process, these substances can cause significant friction and impact on the dust removal bag. Therefore, it is necessary to choose dust removal bags with high strength and wear resistance to ensure the long-term stable operation of the dust removal equipment.

In summary, the selection of filter bags by cement plants must consider many factors, including high temperature resistance, filtration efficiency, corrosion resistance, strength, wear resistance, etc. Therefore, for cement plants, choosing the best dust collection bag is very important. Only by selecting the cement filter bag that is suitable for them, using and maintaining it reasonably, can the long-term stable operation of the dust removal equipment be guaranteed.
