Pneumatic conveying on the other hand includes systems and solutions in two main categories dense or dilute phase both of which can be facilitated in a positive or negative pressure. Pneumatic conveying solutions are considered ideal for medium to long distances, while their small footprint, maintenance elimination, easy expandable and yet the more hygiene and sanitary design are only a few of their benefits in comparison with mechanical.

There is no ‘one fits all’ solution as in many cases even in the same factory, even for the same raw material a different type of conveying is selected simply because another factor comes along to a specific process step.

A proper design put into place right from the start is for great importance to reach a “get it right the first time’’ approach, which saves significant costs in the long run both in efficiency and maintenance while the majority of the cases ends up out of specs or inconsistent final products.
