What are the possible machines to generate air for pneumatic conveying?
To generate the air required for conveying, a regenerative turbine, a rotary lobe blower, or high-pressure fans can be used.
Three-lobe rotary blower ASR3 – type Roots
We have been supplying compressors for more than 60 years, when we started representing Aerzen of Germany. The 3-lobe rotor blowers of the ASR3
Regenerative turbine Blower
Regenerative turbine Blowers or side channel blowers are reliable and efficient equipment used for different applications, mainly for pneumatic transport, with flow rates up
HT high pressure centrifugal fan
HT high pressure centrifugal fans have been designed trying to achieve the highest possible performance in applications where high air flow rates are required
What are the necessary accessories to form a pneumatic conveying system?
Among our accessories for pneumatic conveyors, the HSP rotary valves, HSD extraction rotary valves, and HSG rotary valves, stand out, ensuring the loading and unloading of products into the pipeline with absolute tightness. The VTN and VTNGa valves allow diverting pneumatic transport lines to different discharge points.
HSD rotary airlock valve for vertical passage or extraction
The HSD vertical discharge valve is a dust control system used as a seal in the discharge of pneumatic conveying systems, under air filters
HSP rotary or horizontal airlock valve
Specially designed for product intake in horizontal flow in pneumatic conveying lines, the HSP rotary valve allows an ideal mixing of the product with
HSG rotary airlock valve
Like any rotary airlock valve, its function is to allow the flow of the product, without letting the air escape. This model is designed
VTN pneumatic conveying diverters
The VTN Diverter Valve is used for the pneumatic conveying of products without the need to empty the pipeline. Thanks to their innovative circular
VTNGa Pneumatic conveying rotary diverter
New concept in equipment for pneumatic conveyor track changing The design of the VTNGa diverter valve, allows to divert products by turning a rotor,
Self-adjusting valve for pneumatic suction conveying VAR
Ideal for lowering energy consumption in the pneumatic parallel suction conveying system This valve is employed as a substitute of non-self-adjusting valves that are
Air-to-Air Cooler for Pneumatic Conveying
In the case of using a compressor as the air generator for transportation, there is a significant rise in temperature. Therefore, for some sensitive products, it is advisable to interpose an air-to-air cooler. Examples of this need may include the transportation of sugar or certain plastics.
Frequently Asked Questions
A pneumatic conveying system is a way of moving a bulk dry powder or granular product by mixing it with a gas, typically air, which carries it through a pipeline.
In dilute phase pneumatic conveying, particles slide through ducts at high speed with a large amount of air at low pressure. It can be either pressure or vacuum driven.
Vacuum pneumatic conveying, or suction conveying, is an efficient way to move solids in grain or powder form, which are fluidized by the air generated by the vacuum pump. They then flow freely through the pipes to their destination.
It is used across industries for the movement of powders and granules. It has several key advantages over mechanical conveying systems such as screw conveyors or bucket elevators.
1-It allows for transportation routes of highly variable geometry, without the limitations of the mentioned systems, which generally only allow for horizontal and vertical transport.
2-It leaves the installation much cleaner of residue from the transported product, upon completion.
3- It takes up less space and is cleaner for the surrounding environment, as it is a closed system.
The advantages of dilute phase pneumatic conveying include flexibility for transfer in limited or small spaces, dust suppression in the environment, and easy maintenance.
Among the advantages of vacuum conveying are dust suppression and leak containment. It can also be applied in explosive atmospheres, with secure and graceful receivers, adapting the system to customized demands.
With their experience in implementing pneumatic and mechanical conveying systems, Prillwitz has the necessary technical knowledge to adapt different machinery to the particular characteristics of the product being handled.
