Pneumatic conveying
Thread Content
Does anyone know which company’s pneumatic conveying pumps perform well? It involves using compressed air to transport small solid particles; the pipes we use tend to get clogged often, which is really troublesome!
McCob’s is pretty good; we use theirs, and we haven’t encountered the issue the original poster mentioned. You can take another look for specifics.
It’s not necessarily a problem with the fan. As long as the fan isn’t struggling to breathe, it’s fine. It could also be a problem with the piping; avoid too many bends and ensure there are no leaks. It could also be a problem with particle agglomeration.
Typical powder transfer fans use Roots blowers; the inner walls of the transfer pipes should be polished, and the radius of curvature of the pipe elbows should be large. Shanghai Bolong Powder Engineering Co., Ltd. is a professional powder conveying engineering company.
Hehe, our company uses a WILDEN powder pump for transporting powders, and the results are quite good. I’m not sure if it’s the kind you’re talking about!
Pneumatic conveying is a complete system, and problems cannot necessarily be solved simply by replacing the fan.
I like pneumatic conveying; if the original poster has any questions, we can discuss them together. It is necessary to study the particle distribution of the material conveyed by the poster: whether it is dense-phase conveying or columnar-phase conveying, continuous conveying or intermittent conveying, negative-pressure suction conveying or positive-pressure forced conveying. In 90% of cases, blockages in pneumatic conveying are not caused by the fan; if the problem were due to the fan, it would usually occur at the inlet and the first bend. Instead, issues such as uneven air pressure caused by the filter bags and pipelines, as well as certain properties of the material itself such as collision and adhesion, need to be examined separately. I hope the poster will participate in these discussions.
I think using a Roots blower or a centrifugal blower will suffice; they are generally divided into two types: positive pressure delivery and negative pressure delivery. You can go and investigate specific manufacturers to see how well other manufacturers use them! Decide on which one to choose in the end!
I took a look, and what you said does seem reliable. There are various reasons for pipe blockages, and no conclusion can be drawn from the information provided by the poster.
Why hasn’t the original poster continued the discussion? In communication, one shouldn’t just ask questions without explaining the current situation
The BLACKETMER powder transfer pumps from the United States are good
