We would like to introduce a case where we supplied our "Brodisk Mini" to a powder quantitative supply equipment manufacturer due to concerns about bridging with polymer coagulants. After reviewing the hopper diagram and discussing the properties of the contents, we determined that there were no particular issues. The manufacturer requested to loan this product to obtain user consent for the adoption of the Brodisk, and after the loan, we received consent from the end user, leading to its adoption. Since its introduction, it has been operating smoothly without any problems. 【Overview】 ■ Target Equipment: Polymer Coagulant Dissolution Device ■ Hopper Diameter: 380φ * For more details, please refer to the PDF document or feel free to contact us. * Our website features numerous case studies.

This is an introduction to a case study implemented as a countermeasure for the issue where "wood powder" accumulates on the walls of the dust collector hopper and occasionally falls in clumps, causing the discharge rotary valve to stop. A total of 12 standard blow disks, three on each side, were installed. By using a controller with six solenoid valves, the blow disks are divided into six locations and sequentially air-jet two at a time, effectively resolving this issue. This product ejects air in a 360° direction along the inner wall of the hopper from the periphery of the elastic disks set on the inner surface of the hopper, thereby easily eliminating the accumulation of wood powder on the hopper walls in this case.

Here is an introduction to a case study on bridge prevention using a relatively small hopper. The material is said to be an elastomer powder, and from what I saw of the sample, it contained a significant amount of powder. Since a test was requested, we lent the necessary quantity of our equipment for the experiment. The results were as expected, and the bridge was resolved immediately. In this case, we installed one Brodie disk (BD-15) on each of the three inclined surfaces, for a total of three. The three disks are turned ON and OFF simultaneously using the controller (C-SV1). [Hopper Conditions] ■ Size: 200×500 ■ Shape: Three inclined surfaces, one vertical ■ Discharge: 40φ from the lower end of the vertical surface *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous case studies.

Regarding the new material, we consulted about bridge measures as we are newly manufacturing the hopper. This is a case where we were contacted because they want to adopt our equipment, as the material is finer than conventional materials and the hopper discharge diameter is also small. For a hopper with a diameter of about 600mm, it is common to install 2 to 3 blow discs (standard type: BD-15), but in this case, in addition to 2 standard types, we installed 2 "blow disc minis" nearby due to the relatively small discharge diameter of 80mm. After installation, we received feedback that "no troubles have occurred at all, and it is operating smoothly." 【Overview】 ■ Hopper diameter: 600mm ■ Hopper discharge diameter: 80mm ■ Material name: Talc ■ Material particle size: D50 of single-digit microns ■ Material apparent specific gravity: approximately 0.3 for loose, 0.5 for compact ■ Material angle of repose: about 40° *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous case studies.

This is an inquiry we received from a repeat customer regarding bridging issues with film grinding products. Film grinding products can be troublesome, and since we were unable to see a sample this time, we suggested considering four Brodie disks (BD-15), which are somewhat over-spec for an 800mm hopper, along with a controller (with four built-in solenoid valves). Ultimately, they decided to use three Brodie disks and a controller (with one built-in solenoid valve), which seemed to carry some risk, but it worked out well. From the perspective of preventing bridging, a larger discharge diameter is always better.

This is a case adopted by a factory primarily engaged in the manufacturing of refractory materials. The hopper in question has a sufficiently large discharge area, and while bridging does not occur, there was an issue with residual material in the four corners due to its square shape. Based on past experience, we advised installing the equipment closer to each corner, and it was set up accordingly. After implementation, the user has reported that they are now able to discharge the entire amount. 【Overview】 ■ Target hopper: Weighing hopper ■ Hopper shape size: Square, 1000×1000 ■ Hopper discharge area size: 300×300 ■ Target material: Mixtures including calcium hydroxide *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous case studies.

This is a case where a Brodie disk was installed in the hopper of a powder processing test device at a chemical company. The material being processed was quite fine and had poor flowability, and the discharge from the hopper was through a butterfly valve, which contributed to bridging issues. The discharge diameter was relatively small, making it crucial to address this area first. Therefore, two Brodie disk minis were installed in this vicinity. Additionally, two Brodie disks were installed above, resolving the problem. However, later on, the processed materials varied greatly, and some of them had a low specific gravity and were prone to scattering. To suppress dust dispersion, a controller with four solenoid valves was introduced.

We would like to introduce a case where our "Brodisk" was delivered to a manufacturer that produces powder-related equipment. This was a project for a new customer, who requested, "The material frequently causes rat holes, so we would like you to take sufficient measures." To ensure thoroughness, we installed a total of 8 units in 2 tiers, with 4 units for this hopper. During the on-site trial operation, there were no troubles at all, and we received positive feedback. Since our product is an economical device, increasing the number of installations does not significantly impact the total cost. In this case, the controller remains the same whether 4 or 8 units are installed, so the cost difference between 4 and 8 units is not substantial. Therefore, it is very rational.

We would like to introduce a case where we adopted a solution to improve the issue of unstable discharge from the screw at the bottom of a gently sloped hopper. Since it is a conical hopper, it is common to install one standard Brody disk "BD-15" on each side for a hopper of this size (a total of four). Additionally, the installation locations are centered on the left and right of each side. However, in this case, the number of installations remains the same (four), but the installation locations have been moved closer to the corners of the hopper. By doing this, it is possible to reduce the risk of material remaining in the four corners of the hopper.

This is a case where there was a large amount of retention and a long retention time in the dust collector hopper, leading to the occurrence of bridging. In the case of a dust collector hopper of approximately 2000 square units, it is common to install 8 "blow disks," but since there are cases where retention is allowed up to about 2/3 of the hopper capacity, 12 disks were installed instead. After implementation, there were no occurrences of bridging, and the time required for discharge was also reduced. 【Overview】 ■ Hopper size: 2000×2000 ■ Discharge outlet: 250 square units ■ Target material: Water treatment chemicals ■ A total of 3 disks were installed: 1 near the discharge outlet on each side and 2 above that ■ A controller with 6 solenoid valves was used to sequentially turn on air in time intervals, with 2 blow disks at 6 locations *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.

We would like to introduce a case where a blow disk was adopted to address the poor discharge of collected dust. There were no issues during continuous discharge from the dust collector's hopper, but when dust was stored over the weekend, it became very difficult to discharge even with the vibrator running at the beginning of the week. Therefore, the blow disk was adopted. After the introduction of this equipment, it has been evaluated that smooth discharge is possible even after several days of storage. 【Overview of the Material】 ■ Dust collected from electric furnaces ・Bulk density: 0.8 ・Angle of repose: 50° ・Main component: Iron oxide *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.

We would like to introduce a case where our recycling plant (test plant) was used. This time, considering the possibility that the material properties may change in the test plant and that the hopper has a gentle slope, we recommended the BD-20 type, which has a larger air volume compared to the standard BD-15 type, and it was implemented. 【Overview of Usage Conditions】 ■ Target Material - Gypsum board crushed product (no paper content) - Average particle diameter of about 100μm (wide particle size distribution) - Bulk specific gravity of 0.6 ■ Hopper - Capacity of 4m3 - Diameter of 1800φ - Discharge diameter of 200φ - Cone section slope of 45° *For more details, please refer to the PDF materials or feel free to contact us. *Our website features numerous implementation examples.

In the case of the bulk bag receiving hopper, the discharge outlet was relatively small, and bridging occurred frequently due to the input conditions, which is why this equipment was installed. After installation, the user has reported that there have been no troubles at all. We believe that the placement of the bridge breaker is very important. We are open to consultations regarding placement plans that suit the user's conditions, so please feel free to contact us. 【Usage Conditions】 ■ Hopper Size: 1800×2000 ■ Hopper Discharge Outlet: 150×150 ■ Raw Material Name: Calcium Carbonate *For more details, please refer to the PDF document or feel free to contact us. *Our website features many implementation examples.

Here is a case study from a waste treatment facility in a certain city. "We received a consultation stating that in the storage tank for sewage sludge incineration ash, when the storage volume increases, it becomes impossible to extract using the feeder. It seems to be compacted at the bottom of the hopper." Since we had various experiences with sewage sludge incineration ash, we proposed a solution using a blow disk after reviewing the sludge sample, including layout plans. It was adopted promptly, and the trouble was resolved quickly. This equipment performs aeration inside the hopper (along the inner wall of the hopper), so depending on the conditions, it is very effective in addressing compaction caused by increased storage volume and longer storage time. [Overview] ■ Hopper Size - Approximately 3000 × 3000 ■ Blow Disk Arrangement, etc. - One unit just above the outlet on each side, plus two more above, totaling 12 units installed on four sides. - The controller, which incorporates six solenoid valves, sequentially supplies air to two blow disks at six locations with a time difference. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case that was brought to us by the maintenance representative of a fertilizer manufacturing facility. They are experiencing blockages in the hopper section of their manufacturing plant's dust collector and are troubled by this issue. Although bridging phenomena are occurring in other equipment as well, they have damaged the hopper due to measures such as hammering. Therefore, they requested a solution that would not cause damage to the hopper this time. The equipment is designed to utilize air injection from all around the silicone disk installed on the inner surface of the hopper, along with the effects of the vibration of the silicone disk during air ejection. Since it involves air injection and the vibration of the silicone rubber disk, it will not damage the hopper itself. [Overview] ■ Dust collector hopper dimensions: Approximately 1600×2200 ■ Number of blow disks installed: 12 * This time, 12 disks were installed to reduce the risk of residue remaining in the four corners of the hopper. * For more details, please refer to the PDF document or feel free to contact us. * Our website contains numerous examples of implementations, which can be checked via the link below.

This is an inquiry regarding a case where 'the pellets are bridging solidly just above the discharge valve, and it is difficult to resolve this with hammering from outside the hopper.' We had previous experience dealing with similar-sized materials, so we were able to provide information on layout and operating methods based on that. However, the material this time has quite a bit of stickiness on the surface. There was some risk involved, but we were able to achieve good results. [Overview] ■ Hopper Size: 1000φ ■ Discharge Outlet Diameter: 150A ■ Target Material: Pellets approximately 3mm x 3mm x 5mm ■ Other: This time, the air pressure was set higher, and the air ON time was set shorter. ■ All materials and processing are produced domestically. *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous implementation examples.

Diatomaceous earth is clogging in the hopper and silo, and we received a consultation saying, "We want to do something about it since people are constantly involved." After explaining the features of our equipment, we provided several samples for them to take home. They tried it out in a small hopper from their idle equipment at the customer's factory, and of course, the results were good! They have introduced it into multiple tanks, including square and round hoppers. The blow disk is easy to install (especially no welding is required) and is low-cost, making it reasonable to install many units. [Key Points of Our Equipment] ■ The elastic disk (silicone) is very important in terms of strength and durability, especially considering the risk of foreign matter contamination. The silicone disk of our equipment is exceptionally strong and durable. Once you use it, you will understand! ■ Control (how to aerate?) is crucial! We provide guidance on what should be done. We also have a dedicated controller prepared. *For more details, please refer to the PDF materials or feel free to contact us. *We have published numerous implementation examples on our company website.
