They should be real pleased that you wnt to give out details of their
industrial project.

It's a commercial plant (i..e. it's making logs for retail sale), but
built
from scratch. They've gone through numerous revisions trying to get their
processes to where they need them to be. Things like getting the logs at
exactly the right weight, trying to get the wax/wood ratio right to get
the
burntime/cost effective, etc.

They don't use much wax in the mixture, I don't believe. It's by far the
most expensive component of the logs, so they want to keep that to a
minimum. Just enough to hold it together after it's been pressed. I
don't
think the wax causes any issues in the fireplaces, but I haven't tried one
myself, as we have a gas fireplace.

I'll have to see what details I can give out based on their patents. I'll
try to post back with some details. It's about time for my filial phone
call, anyway.

Finally we are getting somewhere.
Is this a homemade system for the plant, or commercial?
If commercial what is the name of the maker?
Wax ... I would think wax would make a mess in the fireplace?

I am interested... seems to me that it is better than just carting the
load upstairs to be put out for trash... I imagine my collectors hate
getting a pile of dust in the face, I would like to reuse the stuff. I
sometimes feel like putting the dust in the fireplace but am afraid of
the
flash from fine dust loosely thrown in.

My father recently helped set up a plant up here in Canada that turns
sawdust, wood chips, wax, and a little potato starch into molds, which
are then turned into trapasoidal fire logs. I can get some of the
details from him perhaps (like the ratios used), and find out what
pressure is required to form the logs. It's pretty basic stuff,
excluding the transport mechanisms required to churn them out at
reasonably high volume. FWIW, they get about 3 to 4 hours burn time
from
a 3 pound log.

I happened to be in the bookstore and thumbed thru a book on
workshops...
I love to borrow ideas... I only found one.

In a large workshop they were compressing the DC's shavings and dust
into
compressed fire logs...

Anyone in a small shop have one on a small scale, or know where to get
one?

Too bad Onieda doesn't link on that kind of tool from their website.
I am empyting about 35 gal drum per week and would like to
inexpensively
compress them.
