Conveying Systems
PNEUMATIC CONVEYING SYSTEMS
Pneumatic conveying It can be classified into two main categories depending on the pressure principle used: pneumatic pressure conveying and pneumatic vacuum conveying.
They are chosen based on material properties, transport distances, speed requirements and the specific application. Each has its advantages and disadvantages, and choosing the right system depends on the needs and conditions of the particular industry.
Pneumatic pressure conveying
In it pneumatic pressure conveying, el material a granel se mezcla con aire comprimido o gas a una presión más alta que la presión atmosférica.
El material es transportado a través de tuberías a alta velocidad debido a la presión generada, obteniendo producciones elevadas. Este método es adecuado para materiales secos, granulares…
Pneumatic vacuum conveying implica la creación de un vacío parcial en un sistema de tuberías para aspirar y transportar materiales.
Se utiliza la diferencia de presión para succionar el material desde su punto de origen hacia un punto de descarga. La producción es inferior a los sistemas de impulsión pero son más económicos y con menos problemas de emisión de polvo.
Pneumatic vacuum conveying
Depending on the concentration of material in transport, they are classified:
Dilute Phase
It is characterized by a low concentration of product per volume of gas. The pressure-depression is low.
Semi-Dense Phase
A higher concentration of product is transported, at a moderate speed (max. 20 m/s) and medium pressure.
Dense Phase
Its main characteristics are the high concentration of product per unit volume of gas. Medium-high pressure is used.
