Airlift by high-pressure Blower
In air transport with a high-pressure blower, the bulk product is emptied into a rotary valve with specific revolutions per minute, which feeds the quantity given to the piping system.
A powerful fan (blower) channels pressure air (at 0.4 bar) that pushes the product forward.
The loading of the system (ratio kg of transported product to kg of air) is small (3/1), which is why it is called dilute phase pneumatic conveying.
Inside the pipe, the product travels with the air, mixes, and possibly crumbles. It is the ideal system for medium throughput
(5 ton/h) and medium distances (40 m).
There are also different types of rotary valves, depending on the dosage of the product.
