  • DSS055: Coal Mill Safety In Cement Production Industries

    Nov 19, 2019· Vincent explained that the cement industry almost exclusively uses indirect (also known as storage) firing systems with an air swept mill. All air and material goes to a form of intermediate storage like a bag filter, and from the bag filter it mechanically or pneumatically goes to a silo, where it will be fed to the burners.Industries Fruitful,Fruitful provides sustainable productivity to the global mining and cement industries.
