Dense Phase Pneumatic Conveying

Inquip provide Dense Phase Pneumatic Conveying for the moving of difficult, abrasive or friable materials, at a slow speed.

It is extremely important to know the characteristics of your products that are going to be conveyed before choosing your pneumatic conveying system. Dry products such as powder, granules, pellets, sand and flakes can generally be conveyed pneumatically.

Dense phase pneumatic conveying systems, also known as pressure pot pneumatic conveying, are used for moving difficult, abrasive, or friable materials at a low speed but using high pressure through an enclosed pipe which allows no materials to escape therefore is not wasted. Another important aspect of dense phase pneumatic conveying systems is that materials must be permeable or fluidizable.

Dense phase also uses small amounts of gas, this ensures lower power consumption and operating costs. The low velocity of dense phase conveying systems allows for less wear and tear on both the system and the materials being conveyed which minimises maintenance.
