Making an extruder Pellets

[titiyador]

Yes, I think you are right. After I did not try, but some people say put that sawdust and lignin present in the wood plays the role of binder. When I was talking about oil, it was only a little bit for a lot of finished product.

Difficult to see who bought or made a machine at home. In Brittany, the industrialists who manufacture granules add potato starch which is an industrial by-product.

After studying the various solutions, I prefer to buy a branch crusher to have chips available, then I will start manufacturing the press for the production of pellets

If the crushed product is dry and fine enough, and if we manage to handle it in chips so that it arrives like the granules, by tampering with the arrival system, the granules are useless before burning.

I just saw a manufacturer of a pelet machine

what is it worth?

[manoria68]

It holds the road, this machine.
But I'm quite interested in making a copy of the machine from him: http://www.aupoele.fr/index.php?option= ... &Itemid=79
but with a gear motor to rotate at 400 rpm


then, to make sawdust to feed the press, it is more complicated.
I had thought of using a stationary planer 20-30 cm wide, and to make an automatic table that feeds back and forth to plan the logs as at the butcher's shop

In a crusher, to grind logs everything is exorbitantly expensive, and they also grind them too quickly for a press.

And the little casto shredders grind too small sections

why make sawdust when it is worth almost nothing (50 € per ton) in any sawmill.

all the sawmills i know don't know what to do with their sawdust: he gives it free to anyone who wants it

to make sawdust even a planer does not work: it makes chips wider than sawdust

I am wary of all these pellet mashers, mash press style ... I am afraid that it is above all a machine for making pellets feed for cattle, with material easier to agglomerate than sawdust

who has actually seen it work with sawdust without the need to add a binder?

the slightest binder quickly costs too much to kill the profitability of the business

Indeed, the price of sawdust is, for the production of pellets, around 50 to 60 euros per ton.

What a pity to waste it! We still have a long way to go in France!

I confirm: no binder in the manufacture of wood pellets.
it is wood lignin which serves as a binder during extrusion under very high pressure.

I agree for the pelet industry manufacturer and the big machine

but my doubt is the mash press species as shown by manoria68 ... I'm afraid that it does not compress hard enough
