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.

basic information

【Powder Type】 - EVA resin - Graphite - Ammonium phosphate-based materials - Mixed raw materials of clay minerals 【Hopper Dimensions】 Top: 250×250 Discharge section: 30×30 【Product Specifications】 Blow disk: BD-08S-W, 4 pieces Controller: C-SV1 (standard specification), 1 unit 【Key Points of This Equipment】 ■ The elastic disk (silicone) is very important in terms of the risk of foreign material contamination, as strength and durability are crucial. The silicone disk of this equipment is exceptionally strong and durable. Once you use it, you will understand! ■ Control (how to aerate?) is important! We provide guidance on what should be done. A dedicated controller is also available. *For more details, please feel free to contact us. TEL: 06-6777-2777
