Rotary Blowers for Pneumatic Conveying

 

Pneumatic conveying

Pneumatic conveying is the largest market for positive-displacement blowers. Pressures and flows vary depending upon the media being conveyed, system design, materials of construction, change in elevation, and length of the system. Kaeser blowers are limited to dilute phase conveying systems with pressures to 15 psig or vacuums to 15” Hg Gauge. Most dilute phase systems use 3” or 4” piping and blowers such as our DB166C or DB236C. There are four types of conveying systems:
 

  1. Pressure conveying for delivery of product and for longer distances.
  2. Vacuum conveying for unloading, short distances and when the temperature of the air is a concern.
  3. Vacuum-Pressure combined systems.
  4. Closed loop systems (usually nitrogen flooded) for materials that are sensitive to oxygen or moisture. 

Where the piping is connected to the blower determines the system type. If the piping is connected to the outlet of the blower then it is a pressure conveying system. If the piping is connected to the inlet of the blower then it is a vacuum conveying system. Generally speaking, all systems have a material feeder and a material receiver. The feeder supplies the product to the piping system and the receiver is the final destination of conveyed material. The velocity of the air in the piping entrains the material and carries it through the piping system. When the material and air enter the receiver, the velocity is much less so the material falls to the bottom of the receiver and the air is vented out of the receiver.

In many cases, the blower package is not rugged enough for the application or duty-cycle. It is possible to upgrade the existing blower package with process-quality equipment which includes the instrumentation and safeties to make the blower package self-protecting. This will improve the reliability and uptime of the system. With package replacement, you can realize all of the benefits of the Com-paK design.
