Pipe Blockage of Carbon Black During Dilute Phase Conveying
Dear Sir,
We are using following system where fine powder of carbon black (N220 and N330) of having 30 Nano meter size (smallest size = 0.025 Micron) is being conveyed in diute phase.
The only problem we found is blockage of piping and so reduced conveying rate after few days of working. Just with 48 hours of working bends are blocked with sticking carbon black on wall. It also stuck in straight wall but main problem is of sticking on bend wall.
There are 3-4 bends and they are un-avoidable.
What would be solution? We don't mind to pay you for any kind of solution or your help or your guidance.
System : Dilute phase vacuum conveying system.
Blower : 7.5 KW (Approx. 400 cubic meter air flow)
Conveying rate : 1100 Kg./Hr.
Material : Carbon black super fine powder (Some times with moisture)
The simplest solution will be replacing the bends with suitable rubber hose. This material will not build up on the hose as the flexing of rubber hose will shake off the build up. ■
