DUST ENCAPSULATION SANDVIK dust-sealing system We provide a complete range of modular dust-sealing components that can be fitted to feeders, screens and conveyors. Our new screens can be ordered for this system. Our dust sealing cloths WE4000 (Dustflex™) are made of a soft and pliable grade of black rubber with extremely good flexibility and are able to absorb the stresses in a moving seal. Reinforced PVC fabrics should only be used in static (stationary) seals for dust proofing conveyors, etc. It is very important to select the correct grade of cloth or fabric for a particular installation. The WE4000 cloths are fixed in position with the grip strip WE7000 on snap-on profiles, that are mounted on the equipment to be encapsulated.
