· Pneumatic conveying installations
These installactions are designed to move solids in an air current at a specific speed and in a preset direction. Necessary air volume and pressure are calculated in every case according to the distance and the product to be transported.
Generally, a pneumatic conveying installation consists of the following elements
In our pneumatic conveying installations we use standard cylones and valves that we manufacture in series. This allows us quick delivery and reasonable prices.

We strongly believe that pneumatic conveying offers advantages over mechanical systems of transport such as conveyor belts, transporting threads, bucket hoist, etc.
Some of these advantages are:
WORKING SAFETY
-
There is only one mechanical element: the Fan.
-
Minimum costs of upkeep and maintainance. It is not necessary to dismount the whole installation in case of failure.
-
Fan design allows overloading without any risk of motor burnout.
-
There are neither complicated mechanisms, nor parts to wear out
-
The Piping system can be fitted to the building shape, mounting it either on ceiling or walls, taking advantage of empty areas to leave floors free.
-
The pipes can go through the walls, take bends, go up vertically and adjust themselves to any lay-out, where it might be very difficult to adapt mechanical conveyors or hoists.
-
-
Pipes are always clean and do not retain any transported materials or products which allows different materials to be transported with no pollution.
-
This is most important in facilities which transport dietetic or pharmaceutical products. Pneumatic conveying intensifies mixtures as the turbulent current mixes transported products much more thoroughly.
-
Air current improves the product, airs, cools it and leaves it in optimum conditions for packing or any other further process. |

BASIC SYSTEMS OF PNEUMATIC TRANSPORT |
|
A. INDUCTION CIRCUIT  |
-
Low or mid pressure fan.
-
Loading hopper with ventury injector.
-
Ideal for short distances and low performances.
-
A system to transport, load and unload bulk products.
-
Absolutely necessary for rational transport of grains, granulated chemical products and all types of not very fine abrasive or sticky materials.
|
|
B. PRESSURE CIRCUIT  |
-
Mid or high pressure fan.
-
Rotary valves in loading hopper.
-
Good for distances up to 200 metres and with medium to high performances
|
|
C. DEPRESSION CIRCUIT
 |
-
Mid or high pressure fan.
-
Capacity according to pipe diameter.
-
Distance up to 100 metres.
-
We recommend these high efficiency installations for pneumatic conveying of dusty or fine ground product.
-
This system avoids losses in possible leakages of the piping System guaranteeing dust-free working conditions.
-
The fan is always located on the cyclone outlet, preventing product from blocking or wearing out fan rotor.

|
D. CLOSED CIRCUIT  |
|
Pneumatic conveying installation projects and estimation are not a technique of fixed parameters.
Each installation requires a specific empirical study, based on long experience.
Only reputable manufacturers can accept responsibilities.
Contact us if you have a problem. GRUBER HERMANOS, S.A. Technical Department will willingly study best and most adequate for your specific needs.
