What Materials are Candidates for Dense Phase Conveying. The low material velocities, and minimal moving parts that make up a dense phase pneumatic conveying system translates into a conveying system with minimal maintenance, less downtime, less wear and tear on pipeline components, and greater efficiency than other forms of bulk material conveying.

Dense Phase Conveying Systems are also known as Pneumatic Transporters, material transporter, Foundry Sand Transporter. This system is used to convey the material from source to multiple or single destination with the help of compressed air. These method employ higher pressure with lesser air volume per kilogram of weight conveyed compared to LEAN phase system.

conveying line, in a densephase system the material is not conveyed in suspension and usually moves at a much lower velocity than in a dilutephase system. The densephase system, in which the materialtoair ratio can be quite high, can be one of two basic types: • Permeable dense phase: In this phase the material fills the conveying line and travels in intermittent,

Dense Phase Pneumatic Conveying. For conveying fragile or sheer sensitive products, a dense phase system is the better choice. These systems are designed to operate at low velocities to minimize product breakage and sheering. Dense phase uses a pulse of product pushed by a pulse of air, then another pulse of product followed by a pulse of air.

Jan 13, 2011· Dense phase conveying takes several different forms, which makes it difficult to define neatly. For plastics processing, think of it as a system that moves material – ideally plastic pellets – with low velocity and high pressure through the pipes, with the pellets settling and accumulating on the bottom of the horizontal conveying line.
