[Information] Tips for "Establishing Safety" through Machinery. What is the Safety Category?

Introduction to "safety categories" related to machine control systems and machine safety management.

This document introduces the management of machine safety along with the "safety categories," which are closely related to the machine control system. Safety categories are important indicators for ensuring safety through machine control. By implementing and operating machines with high-level safety categories, it is possible to create a workplace that does not rely on human safety management. [Contents] ■ Overview of the "safety categories" that assess how safe a machine is - Safety Category 1 - Safety Category 2 - Safety Category 3 - Safety Category 4 ■ Reference sites *For more details, please refer to the materials on our company website or feel free to contact us. https://rossasia.co.jp/column/

New Material Clogging Complete Solution "AirSweep"

Using compressed air, completely solve bridge and rat-hole problems in the hopper! 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 nature of the substances, 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 workers having to regularly (or when a clog occurs) go to the site and hit the hopper with hammers or sticks. The completely new proposal that uses compressed air to fully resolve issues like bridging and rat-holing is AirSweep. Examples of resolved substances: 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.

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

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

At Service Concrete'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 batch processing and filling for 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 document 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 its 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 either hammer the silos or climb into them to clean them. Therefore, the "AirSweep Model VA-51 Unit" was introduced. As a result, it saved time, energy, and money from maintenance costs and reduced losses from downtime. 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.*

Let's compare: Fluidizer VS AirSweep

By implementing AirSweep, there are many advantages such as cost reduction, increased production, and prevention of quality deterioration!

This document introduces "Fluidizer" and "AirSweep." While the effective area radius of the "Fluidizer" is small, the "AirSweep" activates the flow of materials with a diameter of up to 2.44m (8 feet) around each nozzle. In addition, we provide a clear comparison of various aspects, including "functionality," "maintenance," and "material control." By implementing "AirSweep," you can enjoy many benefits such as cost reduction, increased production, and prevention of quality degradation. We encourage you to read on. 【Contents】 ■ Functionality ■ Effective Area ■ Maintenance ■ Material Control *For more details, please refer to the PDF document or feel free to contact us.

【Data】It takes more time than expected...

The exhaust port diameter of the ROSS high-speed manual pressure relief valve is equal to or larger than that of the inlet and outlet sides, allowing for the discharge of residual pressure at one of the fastest speeds in the industry.

Scene content: A machine maintenance technician performing regular machine maintenance during the Golden Week. Following company rules, they search for the residual pressure relief valve to shut off all power energy to the machine, cut off the supply air, and begin venting the residual pressure air in the piping. With a typical ball valve, it takes much longer than expected to vent all the residual pressure air in the piping. If one approaches the machine with the mindset of "Well, as long as it's mostly vented, it's okay," the compressed air that is still present may suddenly cause the cylinder to move.

[Case Study] Resolving blockages and alleviating stress in the manufacturing site.

A case in which significant improvements in material flow and worker safety have been confirmed.

Bunge is a U.S.-based agribusiness and food ingredient manufacturer that is working to improve the global food supply chain. They were looking for a complete and convenient way to achieve on-demand flow in the operation/process of filling rice bran into full containers. After reviewing options, they decided to implement the "AirSweep System" and installed four "AirSweep VA-06 units" at a 90-degree angle on the sloped walls of the rice bran containers. As a result, they confirmed significant improvements in material flow and worker safety. *For more details, please refer to the PDF document or feel free to contact us.*
