I haven't been following this list for some time, but 4 or 5 years ago
there was a young fellow somewhere up North (In your area) who was
making balls of charcoal+grass+possibly sawdust by tumbling the
material with starch gel. He used a cement mixer with the padles
removed. The stuff formed accredion balls and after drying appeared
quite firm and possibly useful in a gasifier.
What happened to him, and his concepts. That tumbling method is also
used to make things like chocolate covered peanuts and sultanas.It can
also be used for small scale pelletising seeds.

Quoting Thomas Koch <[email protected]>:
I am avare of 2 european biomass densification processes that has
been operating based on the roller principle.
One is a Class developed portable machine that produced chipboard
plate type product in the same shape as corrugated steel plate. The
density was high 900-1100 kg/m3 and the product quality was very
good. The capacity was moderate 3-5 tons pr hour and the
energyconsumption high 4-600 kW (I never understood why?) and the
weight was too high - 20-25 tons - to operate in the fields.
The other was from Silsoe in UK - i only saw pictures - it produced
balls like for barbecue - there was some discussion about this
machine for some years in 1990-1995 but it was never possible for me
to see it.
Conserning your experince about chinese products - i have had
similar experinces - i you ask for the origin of the idea they
become very silent.
Best regards
Thomas Koch
