0151 Rat Hole Measures - Chemical Material Manufacturer

Easily resolve troubles! We will propose installation examples and operating conditions that match the customer's requirements.

We would like to introduce a case of rat hole prevention at a chemical materials manufacturer. Normally, the powder does not pose significant issues and can be discharged from the hopper, but when it contains 3% moisture, its flowability deteriorates significantly. Traditionally, only vibrators were used, and for materials with high moisture content, in addition to the vibrations from the vibrator, air purging from a quick-connect fitting was employed. However, this did not completely eliminate the rat hole issue, leading to the introduction of our equipment, which easily resolved the challenge. [Overview] ■ Hopper Size: 1500×1500 ■ Installation Position: 2 units installed on each side (total of 8 units) * For details, please feel free to contact us. * For more information, 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.

0348 Shortening the discharge time of corn feed.

For solving problems such as rat hole bridges! Introducing case studies of Brodisk implementation.

There have been instances of rat holes occurring in the feed silo, and we have received inquiries about not being able to discharge within the specified time... We want to do something about it... As usual, we reviewed the silo diagram and proposed the arrangement of the blow disk, which was promptly implemented. After the installation of the equipment, we were able to discharge approximately 4 tons in a stable manner within about 10 minutes. There were constraints on the compressor capacity, but the customer adjusted the air pressure, air ON time, and air OFF time in various ways to find the minimum air consumption conditions. [Overview] ■ Material: Corn (powder + grains approximately 5mm) *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.

Elimination of the bridge in elastomer crushed products (powder).

You can set the air ON/OFF time at will! Introducing case studies of Brodisk deliveries!

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.

Elimination of the bridge caused by the repurposing of the feed tank.

Introducing a case study on the implementation of a Brody disk for silo bridge prevention.

This is a case study on bridge issues in feed silos. We received an inquiry stating that a silo for crushed feed rice had started to experience bridging when repurposed for other feed types. The details of the new material are unclear, but previously, discharge was facilitated by vibrating plates. Based on related information, we provided guidance on the placement of our equipment, which was subsequently adopted. After the installation of our equipment, it has been evaluated that bridging no longer occurs. [Overview] ■ Silo diameter: 2500φ ■ Discharge diameter: 500φ (further narrowed below this) ■ Hopper section slope: 45° *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous case studies.

0370 Promotion of the outflow of titanium dioxide mixture

An example of installing a larger number of broad disks/broad disk minis to mitigate risks.

This is a consultation request from an engineering company. Due to the discharge diameter being 3S and relatively small, we installed two Bro-Disk Minis at different heights in this area, and four Bro-Disks on the circumference above, for a total of eight units. A key point this time is that the Bro-Disk Minis installed below have a lower air flow compared to the Bro-Disks, so we have conducted two consecutive air ON operations. After delivery, we received feedback stating, "The Bro-Disk Minis installed near the discharge area were absolutely necessary." [Overview] ■ Hopper diameter: 600φ ■ Discharge diameter: 3S *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 through the link below.

0376 Prevention of clogging in powdered activated carbon

Introducing a case where a blow disk was installed in the powder activated carbon feeding hopper with two lines.

This is a case adopted by a facility primarily producing functional resin products. There are two lines with hoppers, and one line has a significantly small discharge diameter from the hopper, which increased the risk of bridging. After hearing the details, we provided a countermeasure proposal, which was immediately implemented. Since the installation of this equipment, we have received feedback that bridging and blockages have not occurred. 【Overview of Bro-Disk Arrangement】 ■ Line 1 - Four Bro-Disks arranged on the circumference 200-300mm above the discharge section ■ Line 2 - Four Bro-Disks arranged on the circumference 200-300mm above the discharge section - Four Mini Bro-Disks arranged on the circumference 100-200mm above the discharge section *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous implementation examples, which can be accessed via the link below.

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. You can check them from the link below.

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.
