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.

basic information

【Product Specifications】 ■ Brody Disk BD-15S-B, 8 pieces ■ Controller C-SV4, 1 unit 【Key Points of This Equipment】 ■ The elastic disk (silicone) is very important in terms of strength and durability due to the risk of foreign material contamination. Our silicone disks have excellent strength and durability. You will understand once you use it! ■ 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. TEL: 06-6777-2777
