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, the bulk material is mixed with compressed air or gas at a pressure higher than atmospheric pressure.
The material is transported through pipes to high speed due to the pressure generated, obtaining high productions. This method is suitable for dry, granular materials…
Pneumatic vacuum conveying involves the creation of a partial vacuum in a piping system to vacuum and transport materials.
It uses the pressure difference to suck the material from its point of origin to a discharge point. Production is lower than drive systems but they are more economical and with fewer dust emission problems.
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.
