It was installed in the hopper section of the dust collector for the pulverized products from the jet mill. The particle size of the pulverized products from the ultra-fine grinder is very small, and therefore the flowability is poor, making continuous discharge from the hopper difficult, but we were able to resolve the issue. Basically, this hopper does not store the pulverized products, and it was considered to act as a bridge just above the discharge section, so we installed four standard devices in this area. Additionally, there is a knocker that was originally installed at the top, which is also operated to remove any material adhering to the wall. 【Overview】 ■ Material: Electronic functional materials (average particle size: several microns) ■ Bag filter hopper discharge diameter: 125A * For more details, please refer to the PDF document or feel free to contact us. * Our website features numerous examples of implementations, which can be checked via the link below.

At the wood biomass-related facility, we resolved the bridging issue occurring at the top of the discharge screw feeder of the wood powder silo by introducing aeration and vibration bridge breakers as proposed by our company. It seems that the customer frequently experienced bridging since the initial installation of the equipment, and only the amount necessary for discharge was fed in to minimize the occurrence of bridging. However, even so, bridging phenomena occurred with a certain frequency, and when it got clogged, it was addressed by poking it from above with a stick. The introduction of the blow disk improved the discharge troubles and freed the operators from the dangerous task of addressing the issue from the top of the silo. 【Overview Conditions】 ■ About the Silo - Approximately 5000mm (depth) × approximately 3000mm (width), with a bifurcated lower part each having a discharge screw. ■ Location of Bridging Occurrence - Between 500-1000mm above the screw. ■ Material - Wood powder, 5mm mesh screened product, moisture content 30-50% (varies by season). * For more details, please refer to the PDF materials or feel free to contact us. * Our website features numerous implementation examples, which can be checked via the link below.

To improve the outflow and discharge issues from the hopper of fine acrylic resin powder, a blow disk has been installed. The powder has a low apparent specific gravity and small particle size, and before the countermeasure with the blow disk, it seemed to be clogging above the discharge rotary valve. After the countermeasure, it has stabilized and is now discharging properly. If you provide us with details about the powder (name, particle size, and other characteristics) and the hopper dimensions, we can guide you on the appropriate models and operating methods.

Jet milling - Elimination of toner fine powder residue in the dust collector hopper section of the toner manufacturing plant through air classification. Due to the very fine dust generated by fine milling and fine classification, the air knocker was not effectively preventing retention. Although it is a large hopper, eight blow discs were installed relatively close to the discharge section, and it is operating smoothly. The blow discs solve the rat hole and bridging phenomena in various powders and bulk silos and hoppers. They are easy to install and economical. 【Key Points of This Equipment】 ■ The elastic disc (silicone) is very important in terms of strength and durability, especially considering the risk of foreign matter contamination.
