0502 Prevention of Iron Oxide Powder Bridging

0502 Prevention of Iron Oxide Powder Bridging

The discharge diameter is φ1000, and since the circumference is large, the blow disks are installed in two tiers with a slight height adjustment for the four pieces!

We would like to introduce an inquiry we received from a customer stating, "We would like to install a blow disk in conjunction with the modification of the discharge section of the existing silo." The silo has a diameter of φ2000, and a vibro activator was used for discharge. However, due to certain circumstances, the customer requested to remove this discharge device and place our blow disk above it. Since the discharge diameter is φ1000 and the circumference is large, it was decided to install 8 blow disks (in practice, 4 disks will be placed in two tiers with slightly different heights). 【Case Overview】 ■ Name: Iron Oxide ■ Bulk Density: 1.2 ■ Angle of Repose: 50° ■ Adhesiveness: Yes 【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. Our silicone disks are exceptionally strong and durable. Once you use them, you will understand! ■ Control (how to aerate?) is crucial! We provide guidance on what should be done. We also have a dedicated controller ready. *For more details, please refer to the PDF document or feel free to contact us.

0543 Special Case with Ceramic Powder

0543 Special Case with Ceramic Powder

A special case where a rubber sheet with a diameter of approximately 180 mm is installed between the Brody disk and the inner surface of the hopper!

A customer who installed the Brodisk a few years ago has decided to adopt it again. The material is the same powder as last time. Upon checking the condition of the previous installation, it was found that the inner wall of the hopper around the Brodisk elastic disk had worn down, resulting in a mirror-like polished state. As a countermeasure for this issue, we have decided to install a rubber sheet approximately φ180 between the Brodisk and the inner surface of the hopper. While the inner surface of the hopper is as mentioned above, there were no issues with the elastic disk of the Brodisk or the shaft. 【Product Specifications】 ■ Brodisk: BD-15S-B x 4 ■ Controller: C-SV4 x 1 *For more details, please refer to the PDF document or feel free to contact us.

0559 Attached to the hopper for resin grinding material.

0559 Attached to the hopper for resin grinding material.

We want to implement cost-effective measures due to rising costs! We will guide you on a rational arrangement of broad disks and introduce case studies of their implementation.

We would like to introduce a case regarding the installation of a "hopper for resin grinding materials" handled by Minagi Co., Ltd. The hopper for relay use comes with an agitator to prevent bridging; however, its position is not ideal, leading to the occurrence of bridging. Changing the position and shape would incur high costs, so we were consulted on how to address this issue cost-effectively. After reviewing the detailed drawings of the hopper, we provided guidance on a rational arrangement of the blow disks that would not interfere with the existing agitator. We lent out the blow disks for testing, and upon successful trials, they were implemented. [Case Summary] ■ Issue - Changing the position and shape of the agitator would incur high costs, so a cost-effective solution was sought. ■ Result - Provided guidance on a rational arrangement of blow disks, lent out blow disks, and after successful testing, they were implemented. *For more details, please refer to the PDF materials or feel free to contact us.

0571 Solve the discharge problem from the vacuum truck tank (such as quicklime, etc.)

0571 Solve the discharge problem from the vacuum truck tank (such as quicklime, etc.)

We recommend adopting models with a large air volume! A case where the problem was solved by a blow disc.

This is an example of a problem solved using a blow disk, based on consultations from operators using special vehicles. The vacuum vehicle discharges what it has suctioned into a flexible container, but due to the degree of tank dumping, there were cases where the powder did not fall. By installing a blow disk in the accumulation area, the problem was resolved. Since the materials being suctioned can vary, including hydrated lime and cement, we recommended adopting a model with a higher air volume. 【Case Overview】 ■ Issue - There were cases where the powder did not fall when discharging what was suctioned into the flexible container. ■ Result - Adopted the BD-20, which has a higher air volume than the standard BD-15 (due to the variety of materials including hydrated lime and cement). - Installed a blow disk in the accumulation area, resolving the issue. *For more details, please refer to the PDF document or feel free to contact us.
