The chemical manufacturer was having trouble with bridging of flake wax, but by adopting the BroaDisk, they were able to easily resolve the discharge issues from the hopper. A controller with four built-in solenoid valves is used for the eight installed BroaDisks. The BroaDisks are turned on sequentially in pairs at four locations. The ON time, OFF time (between ONs), and interval time are set according to the characteristics of the powder (particle size, particle size distribution, particle shape, angle of repose, moisture content, adhesiveness, flowability, etc.), hopper conditions, and powder discharge/supply speed, as the situation regarding powder blockage and bridging rat holes varies. When multiple BroaDisks are installed, it is more effective to turn them on sequentially at multiple locations, as in this case, rather than turning them all on simultaneously. In the case of aeration for powder hoppers like the BroaDisk, it is not necessary to constantly flow air.

Regarding the introduction of the Broa Disk to the large silo, we received a request from the sawmill to send the silo's drawings and to propose the installation locations and quantities. Based on the shape of the silo and the contents (wood powder, no samples were sent from the customer), we proposed the installation locations and quantities based on past experience. The proposal was to install 5 units on one side, totaling 20 units. However, this customer was already using Broa Disks, and it was noted that even with a small number of installations, they were achieving significant effects. As a result of our consultation, it was decided to install 3 units on one side, totaling 12 units. The results have been very favorable and are operating without any issues, as expected by the customer (the site representative). [Overview] ■ Contents: Wood powder ■ Silo size: Approximately 2500×2500 ■ Broa Disk arrangement: 3 units installed on one side, totaling 12 units * For more details, please refer to the PDF materials or feel free to contact us. * Our website features numerous case studies, which can be checked via the link below.

The raw materials are transported by air to the raw material hopper of the bulk bag filling device, and from the hopper, the materials are fed to the bulk bag using a table feeder and a screw feeder. In cases where the materials are being cut out, the raw materials became biased in one direction within the hopper, leading to unstable discharge of the materials. By installing four blow disks and using a controller with four solenoid valves, we solved the problem by sequentially aerating one location at a time. 【Overview】 ■ Hopper dimensions: 1400×1400 ■ Powder type: Fertilizer (final product) <Reference values for aeration sequence and time> ■ Solenoid valve 1: 3 seconds ON / several seconds OFF ■ Solenoid valve 2: 3 seconds ON / several seconds OFF ■ Solenoid valve 3: 3 seconds ON / several seconds OFF ■ Solenoid valve 4: 3 seconds ON / several seconds OFF After the above, set an interval time (several tens of seconds to several minutes) Repeat the above * For more details, please refer to the PDF document or feel free to contact us. * Our website features numerous case studies.

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.

We will introduce a case that resolved rat holes and bridging phenomena in a 1200φ conical hopper. The equipment configuration consisted of a 1200φ hopper, a slide gate valve, a weight-type belt feeder, and an extruder. In terms of the hopper size, it would be okay with four blow discs, but since it would create rat holes up to the upper part of the hopper, we installed a total of eight discs by mounting four in two tiers. Using the C-SV4 controller (which has four built-in solenoid valves), we sequentially turned on the air in four locations, two blow discs at a time. *For more details, please refer to the PDF document or feel free to contact us. *Our company website features numerous implementation examples, which you can check via the link below.

As a countermeasure for the bridging issue in the hopper of the powder activated carbon quantitative supply device, we have adopted the "Blow Disk Standard Type BD-15S-B."

We would like to introduce a case where a BroaDisk Mini was installed to facilitate the discharge of chemical powder from a mobile container with casters. Since it is a mobile container, the air piping was connected with easily detachable couplers. The air source and controller were branched into three directions, leading to three BroaDisks. Previously, when there were discharge issues, it was common to hit the container with a hammer, but with the installation of the BroaDisk Mini, discharge has become smooth without any problems. Consequently, there have been no deformations of the hopper or cracks in the welds. 【Overview】 ■ Material Characteristics: The powder is very fine and has poor flowability; it solidifies when gripped in the palm of the hand. ■ Hopper Diameter: 450φ ■ Discharge Outlet: 200A * 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.
