0228 Bridge measures for polycarbonate powder

Easily solve powder bridges that cannot be resolved with knockers or vibrators!

We received a consultation from a machinery manufacturer who wants to ensure everything is perfect for an overseas project, and we have been adopted for this purpose. 【Overview】 ■ Hopper shape: Conical ■ Hopper diameter: 1600φ ■ Discharge diameter: 150φ ■ Powder type: Polycarbonate powder ■ Powder bulk density: 0.7 ■ Powder characteristics: Prone to bridging, has flushing properties Since this material also has flushing properties, we decided to minimize the air ON time as much as possible and reduce the total air consumption. Therefore, the number of blow discs was set to 8. (Using the same amount of air, aerating in different locations is more effective than aerating in the same spot.) Blow discs are low-cost, so installing a large number of them keeps expenses limited! * For more details, please refer to the catalog or feel free to contact us. * Our website features numerous case studies, which you can check via the link below.

0249 Bridge measures for synthetic resin powder with high moisture content

This is an introduction to case studies on bridge measures for synthetic resin powder with high moisture content.

In this case, the user created an acrylic scale-down size hopper and visually confirmed the fluidization of the powder using a Bro-Disk before applying it to the actual machine. Such cases are rare, but we are pleased that the internal flow of the powder in the hopper was visually confirmed, allowing the customer to understand the effectiveness of our bridge breaker, the Bro-Disk. [Consultation from a certain chemical manufacturer] It has been reported that issues with bridging in the existing plant have frequently occurred, causing troubles. This time, they contacted us regarding the expansion of the plant. (Target Hopper) Type: 2-axis screw feeder hopper Approximate dimensions: 2000×1200 (Material) Name: Synthetic resin powder Bulk density: 0.4-0.6 Particle size: Approximately 500μm Angle of repose: 70° (strong bridging) Moisture content: 30% (Specification air pressure) 0.4 MPa *For more details, please contact us or download the catalog.

0314 Bridge measures for needle-shaped crystal powder

Case of Brody disk adopted for the resolution of the bridge phenomenon in needle-shaped crystalline powder.

This is an example of a consultation from a manufacturing representative of an industrial materials manufacturer regarding the bridging phenomenon of the material "needle-like crystalline powder" in a hopper, and the inability to eliminate residuals at the four corners. This material is a new type, and it seems that existing bridging countermeasure equipment (such as knockers) did not work well. After receiving and reviewing the material sample and hopper drawings, I recommended the selection and arrangement of the blow disks and suggested conducting tests. Immediately, manual air control was tested, and good results were confirmed, leading to the implementation of automatic control through the introduction of a controller. [Overview of Usage Conditions] <Hopper Overview> ■ Dimensions: 1100×1100 <Blow Disk Arrangement and Operation> One blow disk is installed approximately 250 mm from the discharge section on each side, and another one is installed approximately 400 mm above this (closer to the corners). A total of eight blow disks are used, with four solenoid valves operating two disks each in sequence for aeration. *For more details, please refer to the PDF materials or feel free to contact us. *Our website features numerous implementation examples, which can be accessed via the link below.

0569 Measures for bridge issues with resin powder

Eliminating the bridge after adding water! A case where the problem was solved with a Brody disk.

This is an inquiry from a chemical plant regarding bridge-related issues, and it is a case where the problem was resolved using this equipment. 【Overview】 ■Trouble Details and Background 1. Bridges occasionally occur. 2. The frequency of the above is low, and when a bridge occurs, it is dealt with by poking it with a stick, etc. 3. Static electricity became severe, leading to the addition of water to the material. 4. Due to the bridge, it became impossible to discharge powder from the hopper. 5. The use of a blow disk resolved the bridge after adding water. ■Hopper Conditions - Dimensions: Approximately 3000×1500 - Discharge Section: Approximately 1500×350 - Discharge Device: Screw feeder ■Blow Disk Arrangement and Control - Installed in three tiers (upper, middle, lower) on the inclined part of the hopper (four sides). - A total of 36 blow disks are divided into nine locations with four each, activated with a time delay. *For more details, please refer to the PDF document or feel free to contact us.

0234 Bridge measures for fuel powder

Easily solve powder bridges that cannot be resolved with knockers or vibrators!

We have adopted a blow disk for the bridge prevention of the powder tank for fuel. It seems that the initially installed knocker was unable to improve the situation as the powder would compact, but the air aeration system has successfully resolved the issue in one go. 【Overview】 ■ Raw material name: Powder for fuel (for combustion) ■ Loose bulk density of raw material: 0.3 ■ Tapped bulk density of raw material: 0.5 ■ Angle of repose of raw material: 60° ■ Hopper shape dimensions: Conical hopper 1000×1000 ■ Hopper discharge section: 150A, with rotary valve Since the raw material has fluidization properties, there was a desire to minimize the amount of air used, resulting in the installation of eight units, which is more than the typical quantity. It is more effective to turn on multiple blow disks for short periods rather than keeping the blow disks in the same position on for a long time, in terms of air consumption. * For more details, please refer to the catalog or feel free to contact us. * Our website features numerous case studies, which can be accessed via the link below.

0284 Bridge measures for silica powder.

Introducing a case of a blow disc adopted by a powder equipment manufacturer.

This is a request from a powder handling equipment manufacturer. A bridging phenomenon occurred in the raw material feed hopper of the equipment delivered to the user, which was not initially anticipated. After installing a knocker, there was no improvement, and they inquired if there was anything that could be done. We proposed installing a total of four Brody disk standard types: one on each of the two sides and two on the remaining side with a relatively gentle slope, and they decided to implement this solution. As a result, the bridging issue was resolved easily without any particular troubles. 【Overview Conditions】 ■ Hopper Dimensions: 1500×800 ■ Discharge Port Dimensions: 125A ■ Material Name: Silica Powder ■ Average Particle Diameter: Approximately 300 microns ■ Bulk Density: About 0.25 * For more details, please refer to the PDF document or feel free to contact us. * Our website features numerous case studies, which can be accessed via the link below.
