Coal, coke
The design of the dust collectors is not easy due to the high concentration of dust which may cause the explosion. The environment is usually ATEX rate classified.
Application fields
-
material conveying (dedusting of transfer points)
-
material loading (truck or railcar loading)
-
railcars unloading (bunker dedusting)
-
silo dedusting
-
coke industry (crushers, sorters)
The primary task of each dust collector is the dust extraction at the source. The typical example is the installation of P-type dust filter directly on the conveyor belt with the dust returning back into the material flow.
Vertical installation is the most common. However, in case of the limited space, the horizontal design of the dust collector could be used.
The dust collectors for the dedusting of the explosive dust are usually equipped with the pressure resistant filter housing and antistatic filter elements. Additionally, the dust filters may have also the explosion membranes. On the air ducts, the relief valve is installed.
Recommended types
Cartridge filter type P
This robust dust filter has from 9 up to 25 pcs of filter cartridge (filter area 17-99 m2, air volume up to 6.500 m3/h).
The most typical installation is directly on the conveyor cover with the dust returning back into the product flow.
Cartridge filter type M
This dust collector is used as a central dust filter for the dedusting, for example, railcar unloading or loading of the product on trucks / railcars.
