Pneumatic Conveying System Analysis
Conical pipes can be treated as "stepped" pipelines if they are divided in very short lengths such as a few feet. For your conveying system analysis, if you know basic Excel, you can use the calculation method described in my article "Theory and Design of Dilute Phase Pneumatic Conveying Systems" published in Powder Handling and Processing magazine in its April 2005 issue. A copy of this article is available from me upon request.

Thank you very much sir for your help.I am interested in the article.I hereby forward my request for it. My E-mail address is:nazifiilyasu@yahoo.com.Thank you,once again. ■
Flowr Plant.
Interesting topic you might also read some of Mills and mason Aryticles, they are very usefull to explain to others the workings of pneumatic conveying. the pipeline you describe is kind of short , 3.8 mts long.

Pneumatic Conveying Puzzle
The verbal description is a bit difficult to comprehend. A picture (Schematic) would be worth a thousand words.
Specifically, your second paragraph confuses me:
"The plant has a variable diameter pipe of 3.8
metres long, the largest internal diameter being
0.38 metres and the smallest, 0.15 metres."
Are you saying the system is 3.8 meters long? (12.5 feet?) If so, this is very short in terms of pneumatic conveyors.
Then, as I understand you, - the pipe has a largest diameter of 0.38 m. This equates to 15" diameter - which is extremely large in terms of pneumatic conveyors.
Please understand my confusion and clarifly.
My guess, - that a flour plant of 30 t cap./24 hours would have a largest pipe diameter of 3" or 4", but more like 2"-3", and probably distances between 10 meters and 100 meters.

Re: Help Me Out Please! This Pneumatic Puzzle Is Tough.
I will provide a detailed schematic diagram of the system as soon as possible. Thankyou. ■
Schematic Diagram Of My System.
I have attached herewith a scanned schematic diagram of my system.
V=variable pipe diameter (as i described)
F=filter
B=blower
A=grinder
C=cyclone
S=sifter
p=pipes
I have now understood that no solid material flows through the variable diameter pipe.Only the air and some dust that come out from the cyclone pass backwards through it(suction process) to the blower.The blower in turn blows it into filter.
Considering the pipe network(attached), which pipes do i follow to show that the blower installed is adequate for the daily production output?Flour is being produced at the rate of1 bag of 50kg in 5 minutes. ■

Pneumatic Ash Conveying Systems
Sir,
This is for Mr. Amrit Agarwal.
I am given a project to design a pneumatic ash conveying system and as i was searching through google for some knowledge and basics of designing the same, i eventualyy got here in the forum and got to know about ur article in the magazine, which describes the same very professionally.
Please help me in undrstanding the designing of pneumatic ash handling systems.
Thanks & Regards

Help me out please! This pneumatic puzzle is tough.
I am a part 3 student of chemical engineering. As part of my industrial project, I am faced with the task of studying a flour milling plant of a capacity of 30 tonnes in 24 hrs which operates on a pneumatic system. I am required to show whether the power of the blowers installed are adequate for the installed plant's daily capacity.
The plant has a variable diameter pipe of 3.8 metres long, the largest internal diameter being 0.38 metres and the smallest, 0.15 metres. It has 5 short tubes each with a diameter of about 0.1 metres protruding from its sides and conveying different intermediate (and final) products of the milling process at different rates. This variable diameter pipe is suspended and is being supplied air by one blower about 11 kW power.
On the screening section prior to milling another blower stood supplying air to a much shorter variable diameter pipe. In this section, raw wheat is conveyed from gravity separator to destoner and tempering tanks and finally to the first breaker on the milling section.
I have been able to gather the different solids rates of flow from all the various pipe outlets.
I have come across literateratures but all were talking about constant diameter pipes. Considering this system, how do i use my data to show that the blowers are adequate for their work?
Please come to my rescue with relevant articles. ■
