What To Consider When Conveying Fly Ash

This makes fly ash a useful product in blended cement and hollow blocks as well as other building materials. Fly ash used to simply be released into the atmosphere, but new environmental standards now mean that emissions have to be captured and cleaned using air pollution control equipment. Four Considerations when Handling Fly Ash. Pneumatic ...
