Pneumatic Conveyors Systems
The purpose of a pneumatic transport system is to transfer materials from one or more points to a final destination or to a further production process. These processes include mixing, granulation, concentration, transformation, and packaging.
The company realizes “turnkey” projects with innovative and customized solutions.
All conveyor systems designed and produced by RGS Vacuum Systems are dimensioned and built using the company’s decades of experience. The sales and technical teams are involved in development, and the systems are managed by self-developed, dedicated software to ensure they meet the highest performance standards.
The RGS Vacuum Systems team works to identify the right technology for each customer’s specific needs — from technical inspections at the customer’s production facilities, to system design and construction, through to servicing and scheduled maintenance over time.
Advantages
- Short, medium and long distances can be used to transfer products pneumatically.
- The ability to maintain a controlled atmosphere.
- Closed system, therefore there is protection against dust emissions into the atmosphere and also the protection of material transported by external contaminants.
- May have multiple collection and discharge points, with dosage or weighing.
- Flexibility.
To design and build the most suitable and economical transport system to solve customer problems, based on the type of product and the needs of the industry.
Compact Single Phase Pneumatic Conveyors
With reduced dimensions for easy installation for the transport of granular and dusty products.
Compact High Vacuum Conveyors and Compressed Air
Ideal for the transport of mixed powders in semi-dense phase: taking advantage of a high depression and a very low air flow rate, you can use both vacuum pumps with electric motor, and systems with pneumatic ejectors (Venturi). The homogeneity of the product is maintained in both cases.
Suction Units
Three-phase suction units starting from 1.5 kW up to 40 kW. Models with side channel turbine, with high vacuum pump, with hook and lobe pump, can be in mobile version (wheeled up to 15 kW) or fixed, also some models working with compressed air.
Loading Hoppers
Loading hoppers in painted iron or stainless steel, of various capacities and diameters, with discharge systems with butterfly valve, clapet (tilting), and rotary valves.
All models are available in ATEX version.
Food and Pharmaceuticals Hoppers
Load hoppers for BT-H (Blue Tech-Hopper) RGS pneumatic conveyors allow the handling of different types of materials such as powders, granules, and particles of irregular shape.
Electrical Panels
Custom electrical panels interfaced with loading cell weighing systems with PC or PLC systems for recipe management.
Dense Phase Pneumatic Conveying Systems – DPC
Dense phase pneumatic conveying systems are suitable for conveying materials at very long distances by using high-pressure compressed air (> 1 Bar).
The tank is therefore designed to withstand high pressures (PED or ASME certified) and can have a variable volume depending on the design flow rate.
The Pressure Vessel is the heart of dense conveying systems. The conveyor can be made of painted carbon steel, stainless steel AISI 304 or AISI 316. The interior and exterior finishing can be customized according to the needs of customers. All tanks can also be equipped with suitable components for installation in ATEX zones.
The use of high pressure and low air flow allows you to push the material along the pipe to the destination at very low speeds (1–10 m/s), avoiding breakage of fragile materials, segregation of mixtures, and wear of abrasive materials.
* Maximum approximate flow rate, considering an average number of cycles and a bulk density of 1 kg/L
NB: We can realize even bigger engines depending on the customer’s capacity requirements.
Fluidization Kit – AIR-FLUYD
Additional fluidization kit to be installed along the transport line to reduce the friction of the material and consequently the energy required for its transport.
Fluidizing the material is important to minimize pressure losses, balance the pressure inside the pipe, and prevent the formation of obstructions.
Thanks to the AIR-FLUYD kits, it is possible to achieve greater control of the product speed, thus managing to transport more gently fragile or abrasive materials.
They also allow reducing dynamic loads along the pipes and to stop and start the transport with the full pipe.
They are necessary in the case of full pipe, but can also be used in conventional transport in case of products difficult to convey (e.g. abrasive materials and/or materials with uneven grain size).
Ways of Working (Dense Phase)
Batch (or Empty Pipe)
It’s a non-continuous functioning according to which the material, loaded into the pressure vessel, is pushed by compressed air along the pipeline till the destination; at the end of the cycle, both the pipeline and the pressure vessel are empty and all the material has been transferred to the destination.
This kind of convey is suitable for short/medium distances (up to 50–60 meters).
Full Pipe
Expects functioning cycles according to which the pressure vessel is loaded and emptied, pushing the material little by little along the pipe. After having filled all the pipeline, the material begins to be discharged into the destination with very low speed.
This kind of convey is suitable for reaching very long distances (beyond 100 meters) and for conveying very fragile or very abrasive materials.
Full Pipe Continuous
When continuous functioning is required, we can use a twin system with two pressure vessels working alternatively in parallel, pushing the material along the same pipe.
