Cement plants develop sustainable concepts for conveyor belt
transfer points
Cement and gypsum plants have significant problems with dust and material loss at conveyor belt transfers. Conventional side seals are often inefficient, as friction leads to heavy wear and insufficient sealing. The non-contact AirScrape®, on the other hand, floats just above the belt without direct contact. The resulting Venturi effect guides dust and fine particles back into the material flow. In addition, the DustScrape system allows excess air to escape in a controlled manner through a special filter cloth so that the material remains in the transfer area and clean air escapes.
Immediately after installation, up to 98 % of dust emissions and material losses can be reduced. In addition, belt damage, maintenance costs and downtimes are significantly reduced. The innovative DustScrape filter system not only promises a drastic reduction in dust emissions, but also significant cost savings and improved working conditions.
The DustScrape system is characterised by its ability to almost completely eliminate dust emissions at transfer points for fine bulk materials. In closed transfer areas where high pressure can build up, the system provides effective pressure relief and prevents the formation of dust clouds.
Another notable benefit of the DustScrape system is the ability to improve the efficiency of existing active dust extraction systems. The combination with the AirScrape and the targeted air supply increases the overall efficiency by at least 50 %. This leads to further energy savings and lower maintenance costs.
