Mechanical briquette press
(OP)
Dear Sirs,
we have bought a mechanical piston operated briquett press and we have a question regarding mechanical briquette presses, if anyone has any knowledge about them. We produce briquettes mainly from dryed oak wood, 8-10% kiln dryed.
The problem: we have a mechanical briquette press from a company Spaenex (Germany)... the output is 300-400kg/h and the power is 15kw. The problem is that the briquets are pressed but they get soft and break very easy.
Our theory is that the problem is something with the conic (tapared) die? The conic (tapered) die is maybe not the right shape, how should the die be like? The die must be smaller at the start and then bigger to the end? We habe so far made 2 dies but we didnt get the best results yet...
With best regards,
Nejc

Were any answers to your question on the physics forum helpful?

We used to heat and dry the straw.
Do you have adjustable jaws after the cone? these are used to control the back pressure in the machine. You need to tighten these up to improve the briquettes.

the press goes from 200kg/h to 400kg/h, it depends on the materials, at the end there are pneumatic clamps(picture attached) to control the back pressuere of the briquette.

The wear at the piston end will control how small you can make that diameter.
Bear in mind that the first 15 minutes of any run is a bit dubious as things haven't got up to temperature. We used to add paraffin to the material during the warmup to prevent sticking, but it wrecked the briquettes of course.
Slightly off topic, how does your mention handle the precompression stage? Ours used an auger to feed material into a pair of jaws that then clamped together, then the piston pushed through from the end and rammed the material into the die.
