BFM Global has partnered with rotary valve manufacturers, including Airlock India and Gericke RotaVal, to develop an alternative to traditional vented surge hoppers made from steel.
"We've combined the benefits of our transparent and flexible Seeflex 040E material with the BFM fitting snap-fit system into a uniquely-shaped hopper with built-in product and airflow separation," says BFM’s technical lead, Matthew Bailey. “The Venting Surge hopper has an internal partition that allows powder to flow down one side of the partition and displaced air to flow up and out the other. It snap-fits into a custom-made spigot that has a matching separation plate.”
