Shaftless screw conveyor calculations
Shaftless screw conveyor calculations
(OP)
Hi,
I am interested in designing up a series of shaftless screw conveyors to convey after centrifuge (25% dry Solids) wastewater sludge and would like to know where to find the necessary calculations for power requirements etc.
I have trawled through the internet and it seems that there isn't too much information about them out there. I was just wondering whether any of the cema publications cover shaftless screw conveyors?
Any help with this is greatly appreciated.
Pete.

If you're serious, be prepared to do some real practical R&D to get the answers yourself, not just a trawl through the internet for what others say.

Both companies were helpful with technical questions I had.

Or are you talking about the rotating tube type, with a spiral ribbon in the periphery?

We are definitely talking about a shaftless screw (i.e. no shaft - screw sits down on UHMWPE liner and has no tail bearing.)
I have also done basic pricing for it and it definitely doesn't look like we have a chance (we got an under-the-table indication on the current pricing and it is pretty cheap as it is).
I would love to do some r&d to develop this product but time constraints never really allow for it - when people want pricing they don't want to wait for months for me to piss around trying to develop a screw conveyor which has been and could be made by numerous other companies around the world.
Cheers for the help though.
