0090 Extrusion molding machine solves the bridge in the quantitative feeder hopper.

0090 Extrusion molding machine solves the bridge in the quantitative feeder hopper.

This is an introduction to a case study on bridge prevention measures for the hopper of a volumetric feeder in an extrusion molding machine.

We installed a Brody Disk Mini in the upper hopper of the twin-screw feeder because the powdered mixing materials occasionally formed bridges. This prevented the occurrence of bridges and blockages, allowing for a smooth flow of powdered materials and stable continuous extrusion molding. Methods to prevent rat holes and arching phenomena in bulk materials include air aeration using air nozzles and impact methods using air knockers or electromagnetic knockers. However, our equipment enhances the fluidization of powdered materials through the following combined effects: - Air flows along the inner wall of the hopper from all around the rubber disk. - The rubber disk vibrates, transmitting that vibration to the bulk materials. While it is not guaranteed that this will work 100% for all materials and conditions, there have been many cases where it has provided a "one-shot solution" in situations that could not be resolved by other methods, and the cost is minimal. If you are facing issues with bulk materials, please consult us. We have published numerous case studies on our website, which you can check via the link below.

0119 Bridge measures for PVA crushed products

0119 Bridge measures for PVA crushed products

Solve the bridge of PVA crushed products with a Brody disk!

We would like to introduce a case study on bridge prevention measures for PVA (polyvinyl alcohol) pulverized products. As a solution for bridging issues with PVA pulverized products, we easily resolved the problem by installing a powder feeder (volumetric feeder, table-type feeder) in the hopper. Our blow disk can be installed simply by making a hole of the specified size in the hopper. No welding or special requirements are necessary. Additionally, it is a low-cost solution. 【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 disk is exceptionally strong and durable. Once you use it, you will understand! ■ Control (how to aerate?) is crucial! We provide guidance on what to do. A dedicated controller is also available. *For more details, please refer to the PDF materials or feel free to contact us. *We have many examples posted on our website, which you can check via the link below.

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.

Elimination of remaining carbon black emissions.

Elimination of remaining carbon black emissions.

There are many varieties of materials, and we received high praise from the customer for solving everything!

We would like to introduce a case where the issue of residual discharge occurring in the weighing hopper was resolved using a "Blow Disk." A customer consulted us, stating that there was a significant amount of residue adhering in the carbon black weighing hopper, and although they attempted to address it with a knocker and a vibrator, it was unsuccessful. They inquired whether the Blow Disk could help. We lent our product to the customer, who installed it in a dummy hopper and confirmed the air injection and vibration. After reviewing the hopper design, we provided recommendations for the appropriate model and configuration. As a result of the implementation, the residual amount was reduced to about 500g. The customer praised us highly, noting that there are many types of materials, and we were able to resolve the issue for all of them.

0214 Preventing Blocking of Wet Powder

0214 Preventing Blocking of Wet Powder

Introducing examples of preventing resin powder blocking inside the hopper.

We addressed an issue at a resin manufacturing company where "the resin powder was blocking in the hopper, making it impossible to extract with the twin-screw feeder." In this case, the raw material had a high moisture content, so the operating pressure was also set higher (resulting in increased air consumption). Additionally, due to the installation of multiple units (20 units), we used a controller with 10 solenoid valves to sequentially turn on the air for two units at a time. 【Flow of Problem Resolution】 1. Upon examining the raw material, we determined from experience that it was quite troublesome. → We proposed a close installation of multiple units. 2. We lent a demo unit, which was installed by the user in their existing hopper for testing. → It was found that there were areas where blocking was not resolved when the distance from the unit increased. 3. We added a "blow disk" to the initial proposal based on the user's requests. 4. The above plan was implemented. → The issue was resolved. For more details, please refer to the catalog or feel free to contact us. *Our website features numerous case studies. You can check them through the link below.
