0300 Aluminum hydroxide rat hole countermeasures

0300 Aluminum hydroxide rat hole countermeasures

Introducing a case of the Brodisk adopted by the engineering department of a chemical company.

This is a project from the engineering department of a chemical company. They are loading products from a bulk bag into a hopper, but the discharge from the hopper is unstable... It has become a rat hole, and they have tried using air knockers and vibrators, but with no effect... They mentioned that they usually tap it down with a bar. We proposed a solution using a controller with four solenoid valves, sequentially turning on the air to two blow discs at four locations. They decided to implement the "blow discs," and the results were as expected, very good. [Overview] ■ Material: Aluminum hydroxide powder ■ Hopper diameter: 1300φ ■ Discharge diameter: 150A * For more details, please refer to the PDF document or feel free to contact us. * Our website features numerous case studies. You can check them out via the link below.

0142 Aluminum hydroxide rat hole measures

0142 Aluminum hydroxide rat hole measures

Smoothly solve issues like the rat hole phenomenon with limited costs!

Here is an example of measures taken against rat hole phenomena in aluminum hydroxide. During the trial operation of new equipment, the air knocker could not resolve the rat hole phenomenon of the powder, so a blow disk was additionally introduced. The problem was smoothly resolved at a limited cost. 【Hopper Overview】 ■ 1000φ eccentric hopper ■ Outlet diameter: 150A 【Powder Overview】 ■ Aluminum hydroxide ■ Bulk density: 0.3–0.5 ■ Particle size: average particle diameter of about 1 micron 【Key Points of This Equipment】 ■ The elastic disk (silicone) is very important in terms of strength and durability due to the risk of foreign matter contamination. The silicone disk of this equipment is exceptionally strong and durable. You will understand once you use it! ■ Control (how to aerate?) is important! We provide guidance on what should be done. A dedicated controller is also available. *For more details, please refer to the PDF document or feel free to contact us. *Our website contains numerous implementation examples, which can be checked via the link below.

0330 Immediate delivery for rat hole measures using cellulose!

Introducing a case study on the implementation of Brodisk for rat hole prevention.

We would like to introduce a project delivered to a machinery manufacturer. "During the load operation after the completion of the equipment, a rat hole occurred," which led to the urgent adoption of our solution. There were only a few days left until the machinery manufacturer was scheduled to ship this equipment, so we promptly delivered the blow disk for retesting. The results were favorable, and we received positive feedback that they could ship with confidence. 【Overview】 ■ Hopper diameter: Approximately 600φ ■ Discharge diameter: Approximately 70φ ■ Raw material: Cellulose (bulk density: approximately 0.2) ■ Equipment configuration: Two blow disks on the upper level and two blow disk minis on the lower level (near the discharge area) *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous case studies.

0461 Measures against rat holes caused by food-derived fine powders

0461 Measures against rat holes caused by food-derived fine powders

The rat hole and bridge phenomenon have ceased to occur, and we are operating smoothly!

As a countermeasure against rat holes, we installed vibrators and knockers, but we received a consultation regarding a case where a bridge formed, causing the material to become more compacted due to degassing. First, we received a few hundred cc of hopper drawings and material samples from the customer. After reviewing them, we determined that there were no significant risks and provided guidance on the applicable models and layout. The rat holes and bridging phenomena ceased to occur, and operations have been running smoothly. [Case Overview] ■ Subject: Unknown name (similar properties to powdered milk) ■ Hopper Diameter: 1200φ ■ Discharge Section: 250×250 *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.

0509 Measures against rat holes in dehydrated cakes

0509 Measures against rat holes in dehydrated cakes

Confirmed effectiveness with manual air injection! The test results are good, and this is a case where it was adopted along with the controller.

At the chemical manufacturer's plant, the dewatered cake is stored in a hopper before being supplied to the drying equipment. However, a rat hole forms in this hopper, which is why they adopted our bridge breaker. After reviewing the hopper drawings and samples, we provided examples of the equipment layout and control. For the layout, we proposed a total of 7 Brody disks (standard type): 3 disks on the central inclined surface of the three surfaces, and 2 disks each on the remaining two adjacent surfaces. Since the user wanted to test the equipment, we lent them these 7 disks, and they confirmed the effectiveness through manual air injection. The test results were favorable, and they have since adopted the equipment along with a controller for automatic control. [Case Summary] ■ Target: Unknown name (although it is a dewatered cake, it appears powdery) ■ Hopper Overview: Approximately 2000×1200 with three inclined surfaces (one surface is vertical) ■ Discharge: Dual-axis feeder *For more details, please refer to the PDF document or feel free to contact us.
