What are the materials of coal machine filter cartridges

The materials of coal machine filter mainly include the following:
Stainless steel coal machine filter element
Stainless steel sintered mesh and sintered felt: These are the main materials for stainless steel coal machine filter elements. Stainless steel sintered mesh and sintered felt have the advantages of corrosion resistance, high temperature resistance, and high strength, and are suitable for harsh underground working conditions.
Stainless steel skeleton: The skeleton part of the filter element is often made of stainless steel to enhance the structural strength and pressure bearing capacity of the filter element. Some filter cartridges may also adopt an inner and outer double-layer skeleton design, and set up a central structural support rod to withstand greater pressure differences.

Fiberglass coal machine filter element
Fiberglass, as a supporting material, can enhance the filtering effect and pressure bearing capacity of the filter element. Meanwhile, glass fiber also has certain corrosion resistance and high temperature resistance.
Other composite material coal machine filter elements
According to specific application requirements and working conditions, coal machine filter cartridges may also be made of other composite materials to meet specific filtration and performance requirements.

In summary, there are various material choices for coal machine filter cartridges, mainly determined by the type of coal machine, operating conditions, and filtration requirements. In practical applications, it is necessary to choose according to specific circumstances to ensure that the performance and lifespan of the filter element meet the requirements for use. At the same time, it is also necessary to pay attention to the maintenance and replacement of the filter element to ensure the normal operation and filtration effect of the coal machine.
