Pneumatic conveying in dilute phase, also known as "low pressure," is characterized by a very low efficiency ratio—typically less than 5 to 10 kg of product per kg of air. In contrast, dense phase pneumatic conveying is a technology developed to move bulk materials in powder or granular form through pipes longer than 500 meters and with flow rates exceeding 100 tons per hour.
The distinguishing feature of dense phase pneumatic conveying is its low transport velocity and high efficiency-to-air ratio, along with its ability to preserve the integrity of the material, even when dealing with mixtures of multiple products.
Regarding pellet transport, it is not always convenient and straightforward; therefore, pneumatic conveying systems have been designed to transfer pellets from a remote silo to a heating plant, which can be located up to 30 meters away. Pellet pneumatic transport systems typically consist of a turbine capable of creating a strong vacuum to draw a mixture of air and pellets from the remote silo. The pellets then travel through a dedicated flexible tube made of antistatic material.
Big Bag Unloading Systems
Big bag unloading is the ideal system for emptying bags that contain both free-flowing and compacting products.
The three main models of big bag unloaders are:
- with forklift;
- with hoist;
- with perfect dust containment.
Big bag unloading systems can be accessorized, manufactured in standard versions, or customized according to specific needs.
