Wood Chips
Their is a tube conveyor that has plastic discs connected to a small diamter wire rope as the medium to pull the material through through the tube with the discs
(Discveyor? sorry the name escapes me at the moment) and they are used for long distances in applications from what i have seen.
A lot of wood chip users and transporters use dilute phase transfer over thousands of feet from storage to end use with very good results.

Re: Elevating Wood Chips
Thanks for the comments leon,
The only disc-on-wire machines I've come across have nowhere like the capacity I'm looking for. And pneumatic systems will require power and air filters to avoid dust pollution.
I could use a chain conveyor/elevator, but the capacity is a bit near the top end. Also they tend to be a bit power hungry and these days we should all be looking for low power equipment. So carrying material on a belt must be the lowest power application (mustn't it ?). ■
Wood Chips
We have a lot of woood chip making and handling equipment builders on this side of the pond. And they build their own conveyors too.
Bandit and Morbark and are the biggest ones and they have chippers, chipper blowers, conveyors, in trailer chip reclaimers. harvesters etc.
And they also make the wood chip blowers for their chippers-using a flywheel to power the chipper knives and they will fill a 53 foot live floor conveyor traiiler from front to back-with no hesitation
I can candidly say this as I have seen it it done at a woodsmans field days where they were demonstrating thier largest trailer mounted chipper blower at the time- they have larger chipper blowers now etc.
Both Morebark and Bandit have a huge presence in the chip handling and conveying business.
Bandit and Morbark both make en mass flight conveying units too but a flywheel energised chip blower would do what you want easily with a drop box feeding the flywheel blower that either of them build and they both do custom work.
I can forward the contact numbers if you would like them.

Elevating Wood Chips
This is just a thought that might overcome a problem, but is outside my detailed experience.
I'm looking to move wood chips (200-400 kg/m3) at 300 m3/hr 10m horizontally, 25m at 60 deg incline, then 5m horizontally.
I could use a couple of conveyors and a bucket elevator, but that's three machines.
I could use a sidewall belt with cleats (Flexowell), but those belts are a bit expensive and can the machine can be messy.
I could use a 'snake' belt elevator (Dos Santos), but from a past check that machine is expensive.
Is it possible to use a more simple sandwich belt arrangement just laying a cover belt over the carrying belt up the 60 degree incline using the weight of the cover belt to grip the wood chips against the carrying belt.
Or would this be just a figment of my uneducated imagination..... ■
