Due to the frequent occurrence of the shelf-hanging phenomenon (bridging phenomenon) in the hopper, during the approximately 10-minute weighing time, personnel on-site were breaking the arch from the top of the hopper to discharge the material. Although it was only 10 minutes at a time, this happened about 20 times a day, making it very inefficient. However, after the installation of the bridge breaker, production has become more efficient. 【Hopper Overview】 ■ Hopper Dimensions: 1400×1400 ■ Discharge Outlet Dimensions: 300×300 【Specifications】 ■ Brodie Disk BD-15S-B: 8 units ■ Controller C-SV4: 1 unit *Our website features numerous implementation examples.

As a bridge countermeasure for the large silo of limestone powder, 32 units of the standard type of bridge and rat hole breaker, "Bro-Disk," model BD-15, have been installed. First, 8 units were installed at a position 450mm diagonally above the silo wall along the discharge outlet. The second row consists of another 8 units positioned 600mm above the first row, with the third and fourth rows arranged similarly. The aeration sequence was turned ON sequentially for every 8 units starting from the bottom row. 【Overview】 ■ Discharge outlet diameter: 450A ■ Hopper angle: approximately 60° 【Key Points of This Equipment】 ■ The elastic disk (silicone) is very important in terms of strength and durability, especially considering the risk of foreign material contamination.

This is a case where the shelf suspension and bridging phenomenon of raw materials frequently occurred in a vermiculite raw ore hopper (transport device). Although it is a square hopper, it has three sides that are narrowed, so we installed one "broad disk" on each side. One was placed near the discharge outlet on the central side, and the two on the side were installed 150mm above the one on the central side. As a result, the flow issues of the raw material particles were resolved, and the efficiency of the production site improved. 【Overview】 ■ Raw material size: several mm (scaly) ■ Moisture content: over 5% ■ Specific gravity: about 1g/cc ■ Hopper dimensions: 1000×1000 * For more details, please refer to the PDF document or feel free to contact us. * Our website features numerous implementation examples, which can be checked via the link below.

At the resin pipe manufacturing factory, the rat hole phenomenon caused by calcium carbonate with an average particle diameter of about 2μm occurred frequently. Air aeration using SUS plate processed products and air injection through pipes inserted from the top of the hopper did not improve the situation, but it was resolved with vibration and air injection using the "Blow Disk." This factory also helps with bridge blockage measures for other PVC resins. 【Overview】 ■ Hopper dimensions ・Diameter: 1400mm ・Lower outlet: 200A 【Key Points of This Equipment】 ■ The elastic disk (silicone) is very important in terms of strength and durability due to the risk of foreign matter contamination.

The bridge breaker is often used to prevent rat holes and bridges in bulk materials. There are cases where it is used for dewatered cake-like materials discharged from decanters or filter presses. This time, we received an inquiry to resolve the issue of "dewatered cakes frequently clogging in the vertical rounded chute." Dewatered cakes are considerably more challenging compared to bulk materials, and after explaining past successful cases, we proceeded with testing the "Brodie Disk," which yielded good results.
