Dense phase
BULK MATERIALS OR DUST CONVEYING .
Dense phase pressure conveying moves the material at a relatively low velocity to reduce product degradation, air consumption and abrasion of pipes, elbows and diverter valves.
This type of conveying uses a pressure vessel that operates in cycles, i.e. it is loaded with product to a certain level and then sent to the destination point.
It has applications in sectors such as rubber, food, chemical, plastic, refractory, ceramics, waste treatment and environment.
Dilute phase
PRESSURE OR VACUUM CONVEYING
ROOTS type air blowers are generally used for this type of conveying, which can reach a working pressure of up to 1 bar.
Thanks to the advancement of technology and our own automation department, EUROTEK designs 90% of the pneumatic conveying systems in dilute phase, using blowers for very delicate or extremely abrasive conveying.
We differentiate between pressure conveying and vacuum conveying in the dilute phase.
Pressure conveying
The blower is positioned at the beginning of the conveying line. The pressure generated at the air outlet point of the blower can vary between 0 and 1 bar positive pressure. This type of conveying is widely used for applications where a product needs to be conveyed from one source to several destinations.
Vacuum conveying
The blower is placed at the end of the conveying line. The vacuum generated at the air inlet of the blower can vary between 0 and -500 mBar vacuum. This type of conveying is widely used for applications where the product needs to be conveyed from several points of origin to one destination. One of the most notable advantages of vacuum conveying is that in the event of possible leaks in the layout or in the installation itself, the product does not escape to the outside, thus avoiding dust atmospheres at the leakage points.
