In pneumatic conveying, power consumption is a function of the system design, transfer rate, and convey length. Therefore, a conveying system that transfers 100 tn/hr of a bulk material over a distance of 200 m uses about the same amount of power as a system of the same design that conveys 200 tn/hr of the same material over a distance of 100 m.
Pneumatic conveying line capacity = 2000 kg/h Pneumatic conveying line capacity = 8000 kg/h d = 60 mm D = 120 mm Upickup = 3 m/s Uend = 6 m/s Upickup = 3 m/s Uend = 6 m/s Pressure = 1.2 bar g Pressure = 1.2 bar g 3 /h 3
· The reliability of a pneumatic conveying calculation is depending on: – The accuracy of the input parameters and the degree in which they reflect the reality. – The accuracy of the performance data of the pneumatic installation components. – The completeness of the theory on which the calculation algorithm is built.
A third major consideration in pneumatic conveying is the choice of whether to design for a dilute phase system or a dense phase system. Pneumatic conveying is about moving dry bulk materials with air. You can move a lot of things with air velocity and power, a tornado is proof of that.
Choosing a Pneumatic Conveying System: Pressure or Vacuum Because they are efficient and inherently dust-tight, pneumatic conveying systems provide the most practical method for moving large quantities of dry materials, whether powdered, granulated, or pelletized.
A system like this isn''t always the best option. Here are some of the key disadvantages with pneumatic conveying: Lower Product Volume – Pneumatic systems are typically used for smaller volumes of material, with most pipe sizing ranging from 3-12". That''s not to say they can''t work for higher volumes.

Conclusions and summary. Conclusions from the material density and dilute-phase pneumatic conveying system tests show: The minimum pickup velocity for these two 1⁄8-inch-diameter materials, with an 8-to-1 bulk density difference, requires an average 40.2 percent increase. For identical feedrate and airflow, conveying the lead pellets required ...
· Pneumatic conveying may be catego- riser into several regimes depending on dust loading and transport velocity such as, dilute phase conveying, stream type conveying and dense phase conveying ! ! I. The present study focuses on dilute phase conveying where the particles are fully dispersed in the flow and no deposition occurs.
bulk densities of 16 to 3200 kg/m (1 to 200 lb/ft). As a general rule, pneumatic conveying will work for particles up to 2 inches in diameter @ typical density. By "typical density" we mean that a 2 inch particle of a polymer resin can be moved via pneumatic 3 3
pneumatic conveying system, we can convey at velocities well over 7000 feet per minute (35 m/sec). Plus our conveying capacities range from just a few hundred pounds (100 kg) of material per hour up to 400 tons per hour and conveying distances length. ...
parameters for the correct system calculation. There - fore, Pelletron maintains its own test lab to perform a wide range of pneumatic conveying tests for our customers. The test lab is also the platform for the development of new conveying technologies.

· Pneumatic conveying systems work by flowing air through pipelines, transmitting a propulsion force that moves bulk products through the system from one end to another. Pneumatic conveying demands a pressure difference between the starting and endpoints of the system, which is achieved through the use of compressors, fans, or blowers.
A pneumatic system can convey a product at any place a pipe line can run. Pneumatic conveying can be used for particles ranging from fine powders to pellets and bulk densities of 16 to 3200 kg/m (1 to 200 lb/ft). As a general rule, pneumatic conveying will work

· Calculation of Pneumatic Systems using Gas as Carrying Media Since computers are available, it became possible to build an algorithm that can execute calculations in a time domain, whereby the conveying length is divided in differential pipe lengths, which are derived from the elapsed time increment. The physical principle of this technology is:
Pneumatic conveying involves the use of air under pressure or vacuum to move product material from one or more pick-up sources to one or more destinations through conveying lines. Some of the advantages of choosing a pneumatic conveying system over a mechanical transport system are adaptability to virtually any site configuration, ease of maintenance, and faster ROI.
Determine the Saturation (S), hp/ton (HP), pipe velocity (v), and Pressure Factor (PF) values for the conveyed product from the published saturation table. Calculate the volume of free air (Qs) required: Qs (scfm) = S X conveying rate (lb/min) Calculate the required operating pressure (P, psig): P …

Most of the operating cost of a pneumatic conveying system is in the drive for the air mover. If an estimate can be made of the system air requirements, it is a simple matter to eval-uate the operating cost in cents per ton conveyed to see if it is at an acceptable ...
Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.
