The cement filter bag is a crucial component for dust filtration in the cement production process. It is usually made of materials such as polyester and polytetrafluoroethylene (PTFE). It features high-efficiency filtration and can intercept more than 99% of the dust, ensuring environmentally friendly emissions. It also has excellent chemical stability, resistance to high temperatures, and hydrolysis resistance. Appropriate cement filter bags can be selected according to the process requirements of different stages in cement production, so as to achieve efficient filtration and ensure the stable operation of the production system.
01. Turning stitches
Sufficient stitching to prevent locking and avoid thread breakage.
02. Different Thicknesses
Filter materials of various specifications, materials and thicknesses.
03. Diverse Material Selections
Materials with different properties can be selected according to the working conditions.
04. Mechanized cutting
The cutter distance is adjusted without error, which determines the standard of the bag diameter.

Flue Gas Temperature: In high-temperature working conditions such as at the tail of a cement kiln, the flue gas temperature is usually between 150℃ and 260℃. Filter bag materials with high-temperature resistance, such as P84 and aramid, need to be selected. For processes like cement grinding where the temperature is between 100℃ and 150℃, polyester filter bags can be used.
Filtration Precision: In the processes with extremely high requirements for dust emissions, filter bags with micro-porous membrane coating technology can be adopted, which can improve the dust filtration precision to below 1 micron.
Procurement Cost: The prices of filter bags vary greatly depending on different materials and performances. For example, PTFE filter bags are relatively expensive, while polyester filter bags are comparatively cheaper. On the premise of meeting production requirements, appropriate filter bags can be selected according to the budget.
