Powder hopper

flexible

The Venting Surge Hopper is an angled, tapered connector with an internal partition that allows powder to flow in on one side and displaced air to flow up and out the other. Unlike steel hoppers where you have to open an inspection hatch to see if bridging is occurring inside, the transparency of the Seeflex 040E material gives visibility of product flow. Its flexible walls are malleable, meaning bridging can often be easily freed up simply by massaging the side of the hopper. The hopper is designed to fit into a special Surge Hopper Spigot (on the lower end) that features a weir plate to match the angle of the connector partition. Application As an intermediary hopper above a rotary valve or bag-loading head. Ideal for 'sticky' products that are prone to bridging. Processes that require regular cleaning. (fast and easy to remove and replace) Key Features Internal partition separates product & airflow Transparent to let you see if bridging occurs Easy to remove for cleaning processes Flexible walls allows easy freeing of bridging Physical properties Colour Transparent Construction/ Finish Gloss/Gloss Wall Thickness (+/- 10%) 0.9 mm / 1/32 inch (outer wall) Hardness (Shore A) 90 Tensile Strength (MPa) 40 Elongation (100%) 8 Elongation (300%) 15.6 Ultimate Elongation 593 Tear Strength – Die C (N) 67 100% Modulus (MPa) 8 Dust tight?
