Dense Phase Conveying Equipment

Dense Phase Pressure Vessel

Dense phase pressure vessels employ high air pressure — above 1 bar(g) [15 psi(g)] — and low air volume as the motive force to convey powder or granular bulk solid materials through a pipeline at low velocity. They are designed for high capacity conveying rates and long distances in purged (clear line) and non-purged (full-line) systems. There are no moving parts besides the inlet and vent valves, so less wear occurs. Pressure vessel units are pre-assembled to reduce installation cost, requiring only compressed air source and electrical power.

Omniveyor™ Basic System

The Coperion K-Tron Omniveyor^TM basic pressure vessel system provides manual single point control of convey air pressure and air flow along the entire length of the convey line utilizing Coperion K-Tron’s air injectors. The basic system provides an economical option for dense phase pressure vessel conveying.

Omniveyor™ AIM System

This is a radical departure from dense phase systems that employ manual pressure adjustments and flow regulation with no feedback along the convey line. The Coperion K-Tron Omniveyor^TM Air Injection Modules (AIM) pressure vessel system utilizes Coperion K-Tron's automated air injectors. The Coperion K-Tron Omniveyor AIM system has the capability of providing pressure and flow information at the source, along several points on the convey line and at the destination(s). The system is ideal for processes that change dissimilar material often.

Dense Phase Controls & Air Injection Module (AIM)

The simple to operate dense phase control system is designed with complete control, both in manual and automatic modes, of all components in the dense phase system scope of supply.

The dense phase controls allow the Air Injection Module (AIM) the ability to inject compressed air at strategically placed points along a convey line to control velocity and material-to-air ratio, and thus reduce the potential for convey line plugging, abrasion, degradation and segregation, especially with difficult materials.

High Pressure Rotary Valve

The specially designed high pressure Coperion ZVH rotary valve is used for continuous gentle conveying of coarse granular or pellet size, friable or temperature sensitive materials such as plastic pellets, coffee beans, grains, etc.

A dense phase rotary valve system is ideal for achieving high conveying capacities, even at long distances. These parameters are possible due to the rotary valve’s ability to withstand 3.5 bar(g) [51 psi(g)] while minimizing leakage and through use of the Coperion LMR-X air control unit.
