Vortex Global Solutions has been working with Australian-based business Pneuvay Engineering on various projects around the country.
Pneumatic conveying specialist Pneuvay Engineering had been given a critical task for a key project in Queensland.
As part of the project, the client needed to move its material from bucket elevators into two separate silos.
Luckily for Pneuvay Engineering, the company had an expert partner available to help – Vortex Global.
“We collaborate with Vortex engineers by receiving data on the client’s requirements, including tonnage rates and material type,” Pneuvay Engineering general manager of engineering Paul Malcolm told ABHR.
“We conduct a primary assessment to determine if Aero Slide conveying is suitable. Once confirmed, the details are sent to the UK branch.”
“We work back and forth until we finalise a design that meets the client’s needs.”
The Vortex engineers determined key aspects such as the size of the aero slide, airflow volume, and other critical specifications necessary for the system.
This collaboration ensures a seamless integration of Vortex’s technology into Pneuvay’s engineering expertise, delivering a robust and efficient conveying solution.
While the Queensland project was relatively small – featuring an aero slide of just 25 metres – the success of the project helped Pneuvay Engineering and Vortex Global get involved with a far more complex challenge.
The client’s Victorian site needed a new process line to be installed at the opposite end of the plant, with a much longer conveying distance of approximately 140 metres.
“This project requires a combination of conveying methods,” Malcolm said. “Due to high volumes, and this material needing to be moved under a dense phase scenario, which traditionally demands significant kilowatt consumption and large piping.
“However, by using aero slides, we can achieve high-volume movement with minimal energy use. The only challenge is maintaining a downward slope, which necessitates bucket elevators to lift the material back up before discharging it again.”
This Victorian project, which has been in the works for several years, is expected to benefit from the success of the Queensland installation, potentially helping to secure approval for full-scale implementation.
Tackling alumina leakage
Pneuvay Engineering has also collaborated with Vortex to address issues in alumina handling. Alumina, due to its fine nature, aerates easily and behaves like a liquid when in motion, leading to leakage problems at truck loading facilities.
“The existing valves used by the client resulted in continuous leakage during truck loading. We worked with Vortex to develop a Titan Gate solution, trialled by the client. After several iterations, including modifications to seal arrangements, we achieved a leak-proof solution. Following the successful trial, the client proceeded to purchase 10 additional Titan Gates for their outloading facility,” Malcolm said.

This collaborative approach, where continuous improvements were made based on real-world operational feedback, has ensured a long-term, effective solution for alumina handling challenges.
Optimising lithium conveying systems
When handling materials such as lithium, diverters and maintenance gates play a crucial role in ensuring smooth operation. Pneuvay Engineering relies on Vortex’s range of diverters and gates for its conveying systems due to their superior design and performance.
“Our business specialises in handling powders and granules through pneumatic conveying systems. Vortex products are a perfect fit for our core operations. Unlike traditional valves designed for steam or gas, Vortex valves are specifically engineered for pneumatic conveying, reducing product build-up and ensuring smooth material flow,” Malcolm said.
For lithium and other fine materials, the Vortex diverters and gates provide the reliability and efficiency required for high-performance conveying. Their design helps prevent material stagnation and ensures uninterrupted operation.
Ensuring compliance
Food-grade conveying systems must adhere to strict hygiene and efficiency standards. Pneuvay Engineering’s partnership with Vortex enables compliance with industry regulations while maintaining optimal performance.
“Vortex has food grade seals and components suitable for food-grade applications. They offer various material options, including stainless steel, EPDM, and PTFE, ensuring the product only contacts approved surfaces. Additionally, their designs prevent product accumulation, reducing contamination risks and improving cleaning efficiency,” Malcolm said.
The ability to replace seals without removing the entire valve further enhances the ease of maintenance, making Vortex products the ideal choice for food industry applications.
By leveraging their technology and engineering expertise, Pneuvay Engineering and Vortex Global Solutions continue to drive efficiency, sustainability, and reliability in bulk materials handling, ensuring that their clients receive the right solutions.
