Yes it was a machine that created som puck like lumps out of straw - i think you are right - you need something like 2-500 MPa to form a stable densification in a very short time - thus if you have rollers you will get enourmous dimensions on the axels and bearings . You ca reduce this force if you increase the time - but then capacity drops.
Can you please explain the work of you mate once more for a viking tyhat are not familiar with all the abreviations? (mc wbb ??)

Was this the straw puck machine? I see there are documents in .gov.uk
archives from 1988. If this is the same machine I believe if failed in
field trials because the forces were too great.
My mate Dannny did some interesting work on forcing whole wood through
dies to densify it and basically the wood had to be less than 10% mc wwb
to avoid hydraulic locking.
