1 million pounds per hour, that's 450 t/hr, a lot of HDPE pellets! ■
One Million Lbs/Hr Hdpe Conveying System
Shawn,
From purely technology viewpoint both pneumatic and mechanical conveying systems are viable provided you are willing to accept multilple parallel conveying lines. But from an economic perspective, pneumatic conveying should be more attractive. You have not described how naptha is engrained in the pellets but I assume that it is dissolved and that at the conveying temperatures it will not exude.

Re: Pe Conveying Question
Yes, that is alot of material, but the full scale system will be 6 times the size.
The naphtha is a surface coating, but over time the PE also absorbs the naphtha. About 6 percent by weight is the maximum I have seen.The surface coating is critical for the process in which the PE is used in.
The problem I was concerned over with pneumatic systems is the fact that PE is soluble in naphtha at temperatures above 160F, which could substantially increase the rate of streamer production or just overall PE losses by whatever method.
Thanks again for the replies. ■

So that's about 2700 t/hr in total. At that capacity you can't mess about so I'd say you were looking at a belt conveyor, straight incline 6 degrees. ■
PE Conveying Question
Can anyone suggest a type of conveying system for HDPE pellets that have a residual naphtha layer, 0.3% by weight. This layer is always present and must be present.
The PE needs to be moved about 200 feet has a temperature of 86F. Vertical lift would be 20 feet at most. The amount of PE to be moved is about 1 million pounds per hour. I'm not sure what will work best, mechanical or pneumatic.
Thoughts?
Thank you in advance for any and all suggestions.
