[Data] Ensuring safety through the redundant structure of 2-channel systems.

The HBB (Hydraulic Shut-off & Tank Return Valve) from ROSS is designed to handle not only a single failure (such as a failure of one side of the valve body) but also...

Scene content: A solenoid valve (power control element) was installed to ensure safety through a redundant structure and cross-checking (mutual monitoring) in the two channels. Even in a situation where one valve body was broken and could not shut off the hydraulic pressure, the other valve body operated normally to shut off the hydraulic pressure and return it to the tank, allowing the operator to safely complete the mold exchange.

New Material Clogging Complete Solution Method "AirSweep"

Using compressed air, completely solve bridging and rat-holing issues in hoppers! More than half of the companies in the S&P 500 have adopted AirSweep!

Many manufacturers store and retrieve various substances in containers such as hoppers, but due to the shape of the hopper and the properties of the materials, a clogging issue known as bridging occurs near the outlet. Currently, equipment such as air knockers and air vibrators are used to strike or shake the hopper, but while the noise is loud, the effectiveness is limited, resulting in operators having to regularly (or when a clog occurs) go to the site and hit the hopper with hammers or sticks. AirSweep is a completely new proposal that uses compressed air to fully resolve issues like bridging and rat-holing. Examples of resolved materials: aluminum, coal, copper, diatomaceous earth, gypsum, iron ore, limestone, magnetite, phosphates, shale, soda ash, activated carbon, adipic acid, aluminum chloride, boric acid, chlorine, herbicides, hydrated lime, iron oxide, polyacrylamide, titanium dioxide, zinc, animal feed, brewing grains, cocoa, coffee, corn, wheat, hops, salt, edamame, spices, sugar, starch, acetate, cement, chalk, cork, detergents, fertilizers, fly ash, pharmaceuticals, plastics, polymer resins, wax flakes, wood chips, etc.

New Powder Clogging Solution "AIRSWEEP"

Using compressed air or gas at 0.5 to 0.7 MPa! It can solve clogging issues that could not be resolved with a knocker or vibrator.

"AIRSWEEP" is a new method for resolving powder blockages that allows for complete control of the first-in, first-out flow. With a kit available, it can be easily installed from the outside of the container. It lifts the powder along the walls of the container using compressed air. A typical system consists of an AirSweep nozzle, solenoid valve, controller, and air tank, with a compressed air (gas) usage of only 0.28m3/min. 【Features】 ■ Easy installation from the outside of the container with a kit available ■ Specially shaped nozzle (patented) ■ Composed of AirSweep nozzle, solenoid valve, controller, air tank, etc. ■ Compressed air (gas) usage of only 0.28m3/min in a typical system ■ Uses compressed air or gas at 0.5 to 0.7Mpa *For more details, please refer to the PDF document or feel free to contact us.

[A case study] AIRSWEEP received a perfect score of 10 out of 10.

Guaranteeing a continuous flow! Here is an introduction to a case where we prevented the product from solidifying.

Many materials used in the food processing industry have high oil and moisture content, making them prone to bridging, sticking to walls, and clogging. The company uses a vacuum conveying system that processes materials at a speed of 6,000 pounds per hour. When materials clog, it wastes time, labor, and materials. Therefore, they introduced six "AirSweep VA-06" units. These products are arranged in pairs at the top, middle, and bottom of the hopper to ensure a continuous flow and prevent the product from solidifying. *For more details, please refer to the PDF document or feel free to contact us.*

[Example] Fly ash dispersion rate at night from 0% to 100%

Production increased by 60%! We were able to gain time to perform other tasks.

To manufacture high-quality cement, ready-mix concrete plants often mix fly ash into their products. A concrete company in Pennsylvania had six ready-mix concrete plants but was struggling with bridging issues of fly ash in the containers. Therefore, they installed four "AirSweep units" in one of the fly ash storage containers at the plant. After installation, the fly ash moved very smoothly from the container to the ready-mix trucks, resulting in a 60% increase in production. *For more details, please refer to the PDF document or feel free to contact us.*

[Case Study] One AirSweep solves the problem of sand flow.

The truck was loaded without delays or additional work! An example of starting the move as scheduled.

At the Service Concrete company's ready-mix concrete plant, wet sand was sticking to the container and causing bridging at the top of the pants-leg type outlet, resulting in significant delays in batching and filling transport mixing trucks. To address this, an efficient and effective system was designed, consisting of one "VA-51 AirSweep" directly above the pants-leg outlet, along with an "MCA-45T solenoid valve" and a "CBO 1-12 control box." As a result, it became possible to instantly flow sand as needed. Trucks are filled without delays or additional work and can start moving as scheduled. *For more details, please refer to the PDF materials or feel free to contact us.*

[Case] Resolved a flow issue with old materials from 4 years ago in just 2 weeks.

Maintaining a smooth flow of adhesive asphalt! Continuing the manufacturing process.

Asphalt is made up of aggregates, sand, and asphalt cement, and these materials tend to become compacted and clumped together in silos. In the asphalt product factory in Mexico, despite the installation of electric vibrators, workers continued to have to hit the silos with hammers or climb into the silos to clean them. Therefore, the "AirSweep Model VA-51 Unit" was introduced. As a result, time, energy, and money were saved from maintenance costs, and losses from downtime were reduced. Additionally, workers were able to work safely and focus on their primary tasks. *For more details, please refer to the PDF materials or feel free to contact us.*

"Air Sweep" for material and powder clogging prevention in hopper silos.

Eliminate manual removal work and address labor accident measures. Solve powder clogging that cannot be resolved with knockers or vibrators. *Video and explanatory materials available.

This solution allows for the bursting of compressed air or inert gas at regular intervals, enabling the compressed air (or inert gas) to penetrate between the container walls and the material, lifting the material away from the walls and stirring it, thereby eliminating ridges and rat holes. By flowing compressed air (or inert gas) along the walls of the container and blowing away the material adhered to the walls, it contributes to the internal cleaning of the container and prevents material contamination between batches. ★We offer improvement proposals!★ If you provide the following information, we will submit a "Proposal for Improvement" summarizing product selection and effective installation methods for containers. Please feel free to contact us! L Material name L Container drawing (hand-drawn or punch drawing is acceptable) L Pressure of available air (gas) 【Features】 ■ Powerful bursts to disperse materials ■ Sends shock waves along the inner walls of the hopper ■ Lifts and activates stalled materials ■ Breaks the friction between the material and the hopper wall ■ Pulses with a pre-set sequence *For more details, please refer to the PDF document or feel free to contact us.
