Cement plant coal mill dust collector anti-static dust collector filter bag
Our company absorbs and digests foreign technology, and develops and produces
anti-static needle felt dust collector filter bags according to the needs of domestic
BF gas coal mill dust collection and cement mill dust collection and other industries.
In addition to the process of producing ordinary needled felt, the production of antistatic
filter cloth also requires the incorporation of conductive fiber yarn in the warp of ther
base cloth for the production of needled felt or the mixing of conductive fiber and other
conductive materials in the chemical fiber.
After the concentration of general industrial dust reaches a certain degree (that is, the
explosion limit), such as electrostatic discharge sparks or external ignition and other
factors, it is easy to lead to explosion and fire. For example, face dust, chemical dust,
coal dust, etc. have the possibility of explosion in case of electrostatic discharge. In the
field of bag dust removal, if these dust need to be collected by cloth bags, it is required
that the filter material made of dust bags has anti-static properties.
