0245 Installation to the hopper of the metal powder screw feeder.

Introducing a case of installation in a hopper of a screw feeder for metal powder.

In the metal powder hopper, we installed a conical shape inside to reduce the powder pressure to prevent bridging, but it did not improve. We received an inquiry about trying a Brodie disk. The customer expressed a desire to borrow it, stating, "I would like to avoid installing it suddenly (as it requires drilling a hole in the hopper), and first, I want to check the actual item." Therefore, we attached the Brodie disk to a resin plate that simulated the hopper wall and sent it. The customer connected the air and confirmed the air discharge. After embedding it in the powder inside the hopper and confirming the air discharge in that state, they decided to adopt it. Since then, they have evaluated that it is operating stably. 【Overview】 ■ Material: Metal powder (particle size: unknown) ■ Bulk density: Approximately 2.5 ■ Hopper size: 1300×2000 * For more details, please refer to the catalog or feel free to contact us. * Our website features numerous examples of implementations.

0322 At the fertilizer manufacturing plant

Introducing a case study of the "Brodisk" adopted by a fertilizer manufacturing facility.

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.

Concerns were raised about potential blockages at the discharge section of a newly constructed cement silo, leading to the introduction of our Brody Disk. As there were significant concerns from the user regarding the new plant installation, we lent them a sample of our equipment. After the plant began operation, they reported that the initial concerns were completely unfounded and provided high praise for its performance. 【Overview】 ■ Silo Diameter: 2500φ ■ Discharge Section: 250φ×2 Ports 【Key Points of Our Equipment】 ■ The elastic disk (silicone) is crucial in terms of the risk of foreign matter contamination, so strength and durability are very important. Our silicone disk is exceptionally strong and durable. Once you use it, you will understand! ■ Control (how to aerate?) is important! We provide guidance on what should be done. We also have a dedicated controller available. *For more details, please refer to the PDF materials or feel free to contact us. *Our website features numerous case studies.

Resolving the bridge of resin powder (water-added)

An example of installing a Brody disk to solve the problem of the bridge phenomenon occurring when water is added to resin powder.

This is an example we received from a manufacturer of labor-saving machinery. We were consulted because "the customer (in the chemical industry) started adding water to resin powder, and a bridging phenomenon that had not occurred before began to happen in the delivered equipment." The key point this time is that while the flowability of the resin powder before water addition is relatively good, the angle of repose increases due to the addition of water, and there is a possibility of increasing the amount of water added in the future. In this case, considering that the discharge diameter of the hopper is somewhat small at 100A and the worsening of the angle of repose due to increased water addition, we added four mini blow discs (BD-08) just above the 100A discharge section in addition to the four previously mentioned blow discs. After implementation, we followed up and there have been no troubles; it is operating smoothly. 【Overview】 ■ Product Name: Resin Powder ■ Particle Size: 10 to 1000 μm ■ Hopper Shape: Cone 1000φ ■ Discharge Diameter: 100A *For more details, please refer to the PDF materials or feel free to contact us. *Our website features many examples of implementations.

0397 Prevention of bridge formation of dust containing glass fibers

Prevention of dust containing glass fibers! An example of applying a blow disk to the hopper section of a dust collector.

This is a case where a blow disk was adopted for application to new equipment. The application location is the dust collector hopper section. Since the blow disk injects air along the inner surface of the hopper, it is generally the case that the effectiveness does not change significantly even if the installation position is slightly off. The key point this time is that due to the properties of the target material, the air pressure used is high, the air ON time is short, and air aeration is performed in a pulsed manner. [Overview] ■ Hopper approximate dimensions: 2000×2000 (discharge section 200×200) ■ Blow disk arrangement - 3 units per 4 sides, with 1 unit on the lower level and 2 units on the upper level per side (However, only 2 units are installed on one side due to the inspection port) - Both lower and upper levels are positioned quite low, near the discharge port * For more details, please refer to the PDF document or feel free to contact us. * Our website features numerous implementation examples. You can check them from the link below.

0401 Improvement measures for existing users (calcium hydroxide)

After the implementation of the improvement measures, we have received feedback that there are no longer any rat holes at all!

This is a case inquiry from a user who has already installed a Brodisk. Although they purchased and installed the Brodisk as a measure against rat holes, they consulted us because they observed that the rat holes had not been resolved upon visual inspection of the inside of the hopper during maintenance. As a countermeasure, we advised them to increase the number of Brodisk installations, reconsider the placement, use a controller with four solenoid valves, and review the air piping (such as tube diameter conditions), which they implemented. After implementing this improvement plan, the user reported that there were no rat holes at all. [Overview of Usage Conditions] (Placement overview and control after improvement) ■ Hopper dimensions: 1500×1500 ■ Approximate dimensions of hopper discharge area: 300×300 ■ Placement overview: 2 units on one side, totaling 8 units installed ■ Control: Air is turned on sequentially in pairs with a time delay using a controller that incorporates four solenoid valves. *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.

0404 Measures against rat holes in catalyst raw materials

A case where Brodisk was adopted repeatedly for the expansion of the line.

This is a repeat project that we have been hired for. This project was previously adopted a few years ago, and we received feedback from the user that "extremely good results were obtained." This time, we are being hired again for the expansion of a similar line. In this case, we were informed about the properties of the material measured with a powder tester. We would appreciate it if you could provide such data, but even if only the material sample and hopper diagram are provided, we can inform the customer about the optimal arrangement of our equipment based on that information. Please feel free to contact us. [Overview] ■ Trouble Situation - Rat hole in an 1800φ conical hopper - Discharge diameter is 200A, with a typical rat hole forming directly above the discharge section. ■ Material - Name: Confidential (catalyst raw material) - Particle size: Several micrometers - Angle of repose: Approximately 50° - Bulk density: Loose approximately 0.3 / Dense approximately 0.6 *For more details, please refer to the PDF document or feel free to contact us. *We have many examples published on our website. You can check them via the link below.
