Sawdust pressing with the log splitter - is that possible?

Wood shavings are a very cost-effective heating material, as they can often be purchased very cheaply or already incurred in your own household (circular saw). In their raw form they can be used only in a few suitable heating systems, as briquettes, however, in almost all biomass heating systems. How to press such briquettes with the wood splitter, and what other possibilities there are, read here.

Briquetting presses versus wood splitter

You can buy a good briquetting press, the result is always very good in such a case. However, the cost of such a briquetting press is not low - the press must be very powerful and can generate high pressure, which usually makes it expensive. In addition, there are only a few presses in the trade, which are designed for private use, usually briquettes are industrially produced.

necessary requirements

Briquettes should only be pressed dry (wood moisture 10 - 12%). But the pressure must be so high that a compression of 1:10 to 1:15 can be generated. The briquettes are then held together by leaking resin and the interlocking, broken-up lignin fibers that combine with the cellulose fibers in the wood. With admixtures of wet cardboard or the like, which should hold the briquettes, this is not done.

Conversion of a log splitter

A log splitter with a pressure of 10 tons and more generates enough pressure to press wood into briquettes. However, the splitter must be rebuilt for this purpose to the press. Instructions for this can either be purchased on Amazon (Brikettomat 3000), but there are also some free (often less tested) tutorials on the net.

Tips & Tricks

Sawdust should by no means be burned loose. This can cause deflagration, which can even lead to fires! Also, the calorific value of loose sawdust is almost zero, so that a loose heating would make no sense.
