0575 Alloy powder + resin powder bridge elimination

0575 Alloy powder + resin powder bridge elimination

Only when it gets clogged, manually turn on the air! An example of its use as a bridge countermeasure.

We would like to introduce a case where measures against bridging in the powder material hopper of a press machine are being utilized. There was a concern that the press material (alloy powder + resin powder) could bridge and not fall even when hammering. To address this, we installed one standard Brody disk (BD-15S-B) on the central face of the three inclined surfaces. The user initially consulted us about wanting to try the installation, so after discussing the installation location, we lent them the equipment. The results were favorable, and they have adopted it. [Case Overview] ■ Hopper Overview - Size: 400×400 - Shape: 3 inclined surfaces (1 vertical) - Discharge section: Φ100 flexible *For more details, please refer to the PDF document or feel free to contact us.

0588 Preventing rat holes in the baking soda silo

Examples of resolving issues such as "rat holes occurring" and "nozzles getting clogged"!

Due to frequent troubles with aeration in the existing silo, we consulted and introduced the "Brodie Disk." The contents are sodium bicarbonate, and aeration was being done with nozzles to prevent bridging. However, issues such as "rat holes forming" and "nozzles clogging" occurred, and these problems have been resolved with this equipment. The Brodie Disk is easy to install and economical, but placement is important, so please do not hesitate to contact us. We also offer free rentals of this equipment. 【Overview】 ■ Silo Diameter: φ1800 ■ Discharge Diameter: 200A ■ Target Material: Fine Powder Sodium Bicarbonate 【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. The silicone disk of this 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. A dedicated controller is also available. *For more details, please refer to the PDF materials or feel free to contact us.

0717 Delivery of Brodisk (Brodisk Mini) for the food industry.

0717 Delivery of Brodisk (Brodisk Mini) for the food industry.

The metal detection compatible Brody Disk (mini), widely used in the food industry, has been adopted in the cosmetics industry!

We would like to introduce a case where a model with metal powder mixed into the elastic disk (the air discharge part of the blow disk) was used, so that if the elastic disk were to accidentally break and mix into the powder, it could be detected by metal detectors or X-ray inspection machines. While it is mostly used in the food industry, this time it was adopted by a customer in the cosmetics sector. Since the discharge diameter is quite small, it is very important to implement blockage measures just above this point. We installed two Blow Disk Minis at this location and two more Blow Disk Minis 50mm above this point. A total of four Blow Disk Minis are controlled simultaneously using the C-SV1 controller, which has four solenoid valves, to turn the air ON and OFF. 【Case Overview】 ■ Hopper Diameter: Ø350 ■ Discharge Section: 2S ■ Target Material: Cosmetic raw materials (very fine / particle size undisclosed, name undisclosed) *For more details, please download the PDF or feel free to contact us.

0722 Measures to prevent clogging of powder with high moisture content

0722 Measures to prevent clogging of powder with high moisture content

The purpose is to solve the clogging and blockage of powder through air aeration on the inner wall of the hopper and the vibration of elastic disks (rubber disks).

We would like to introduce a case where a chemical manufacturer adopted the "Brodisk." They had installed knockers as a countermeasure for bridging, but it was not very effective, and they were dealing with the issue through manual hammering. After years of hammering, the hopper became uneven, and they decided to update this part and introduced our product. The results have been good, and it is operating smoothly. 【Case Overview】 ■ Hopper Diameter: Ø600 ■ Discharge Diameter: Ø150 ■ Four Brodisks were installed at a position 250mm from the discharge section ■ Control is set to simultaneously turn the air ON/OFF for the four Brodisks *For more details, please download the PDF or feel free to contact us.

0531 Prevention of adhesion of urethane pellets

0531 Prevention of adhesion of urethane pellets

To prevent adhesion, it is effective to spray air at high pressure! Here are examples of the installation of blow discs.

We received a new inquiry from a rubber product manufacturer who adopted our equipment a long time ago. In the previous project, they used the Brodie Disk Mini to prevent fine powder bridging, and it was well received. Although quite some time has passed since then, it seems they have been using the elastic disks (silicone disks) stably without any degradation or damage. This time, they consulted us because the material tends to stick to the inner surface of the hopper, and they wanted to find a solution. The effectiveness of our equipment depends on the degree of sticking (adhesion), so we first installed one Brodie Disk (standard type) on just one surface, which yielded very good results. Based on the test results, it was decided to install them on each surface. 【Overview】 ■ Material: Urethane pellets ■ Hopper dimensions: 450×450 ■ Discharge section dimensions: 100×100 ■ Transport: Blower ■ Control: To prevent adhesion, it is effective to inject air at high pressure, so the operating air pressure is set higher, and four Brodie Disks are activated one by one with a time delay. *For more details, please refer to the PDF document or feel free to contact us.

Elimination of residue in the hopper of LDPE crushed material.

Elimination of residue in the hopper of LDPE crushed material.

Cost-focused control! Introducing a case that eliminated rat-hole residuals.

After installing a magnet bar to remove metal foreign objects, material began to remain in a rat hole shape at the upper part. We received an inquiry about wanting to address this with a blow disk. We installed four blow disks (standard type BD-15) at the same height on the upper half of the conical section, which resolved the rat hole-shaped residue that was occurring from the conical section to the cylindrical section. There is also the option of turning on the blow disks one by one with a time delay, but since this case is not highly complex, we are focusing on cost-effective control. 【Case Overview】 ■ Residue Situation - Rat holes occurred from the upper half of the conical section of the magnet bar installed in the lower half of the conical section of an Φ800 hopper to the cylindrical section. - The target material is low-density polyethylene granulate. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Preventing Bridging of High Moisture Content Granules

[Case Study] Preventing Bridging of High Moisture Content Granules

Prevent bridging of granules with high moisture content! Introducing case studies from powder handling professionals!

The high moisture content of the granulated material caused bridging at the hopper outlet, but the installation of the Brody Disk and Brody Disk Mini resolved the issue. Initially, you were using an overseas vibrator (air ball type), which was effective but occasionally caused bridging, leading you to contact us. 【Overview】 (Usage Conditions) ○ About the Hopper → Top: 800φ, Outlet: 80φ, Angle of repose: approximately 60° ○ Raw Material → Particle size: approximately 5φ, Moisture content: over 20% ○ Installation Position and Model → The risk of blockage is highest just above the outlet, so two Brody Disk Minis were installed in this location (75mm above the hopper wall from the outlet). → Due to the hopper's radius in this location, a Brody Disk cannot be installed; only Brody Disk Minis can be used. → It is preferable to install close to the outlet, so Brody Disk Minis were chosen. → Two Brody Disks were installed approximately 150mm above the Brody Disk Minis along the hopper wall. *For more details, please contact us or download the catalog to view.
