From 
http://www.woodgas.com
you want the book "Densified Biomass; a new form of solid fuel".

Online book:

I have read as high as 10,000 psi for a ring pelleter. Heating can lower this. 
High density = high presssure.

I have read 1000- 1500 bar (hope I have the correct number of zeros!) bar for 
screw extrution.
