Innovative silo reclaim system and convey unit for Fresh Cement - Bangladesh

Van Aalst supplied an innovative reclaim and conveying system that includes 3 aerated reclaim floors for 3 flat bottom silos and a convey unit for Fresh Cement, Bangladesh.

Innovation is always at the forefront within Van Aalst. This project is a beautiful example of how innovation drives us forward. Our client Fresh Cement wanted to convey fly ash from multiple storage silos to 5 different mills and a silo spread around their cement plant. Van Aalst came up with an innovative solution to fullfill Fresh Cement's in-plant dry bulk transfer requirements.

Reclaim and conveying system design for Fresh Cement

The 3 silos are fitted with aerated reclaim floors designed by Van Aalst. The reclaim floor fluidizes the fly ash for smooth reclaim with minimal energy demand. The 3 silos are connected to 2 suction bins by air slides. A convey unit uses a vacuum conveying process to transfer the fly ash from the suction bins to the filter receiver on the convey unit. From the filter receiver 2 transfer kettles are filled. The convey unit pneumatically conveys the fly ash from the transfer kettles to several mills and a silo around the cement plant using a dense phase positive pressure system.
