How much pressure do you need to make sawdust briquettes?

What Is a Fire Briquette?

A fire briquette is a block of highly compressed sawdust, perfect for firing up your wood stove or fireplace. The saw dust is wood waste, collected by dust extraction from all the machines in our workshop and compressed using an RUF Briquetting Press from Germany. It’s one of the many ways we aim to reduce waste and our impact on the environment.

Why Are Our Fire Briquettes So Popular?

Our fire briquettes are a highly efficient, clean burning, cost efficient and environmentally friendly heat source for your wood heater. In them, there’s no glue or additives, just pure, recycled hardwood sawdust.

Their extreme density and low moisture content means you’ll get a hotter fire while burning less, and there will be less smoke.

Plus, smaller particles and lower moisture content will mean that you’ll have less ash and creosote building up in your flue. While the moisture content of commercially available firewood commonly ranges from 20 - 30%, our fire briquettes are 12% moisture content or below - meaning you’re paying for more fuel, and less water.

With competitive price and timely delivery, Tiantai sincerely hope to be your supplier and partner.

They’re also super convenient, delivered in Canberra on a 1 tonne pallet into your carport or garage, ready to throw on your fire. You can also order a sample box of 12-14 briquettes, which is a great way to test them out and there is less of a waitlist on sample boxes.

Oh and our briquettes are rectangular so they are super easy to stack and won’t roll around like cylindrical firewood tends to.

Spirilis,
I've done a fair amount of research and some prototyping. Here is what I can tell you. To make a briq. with hardwood sawdust, you will need roughly 24,000 psi. With that said, if the end or your briq that you are pressing against is 3x3, then you have 9 sqin. So, you will need 216,000 psi. Hardwood really does require that much pressure to get the lignin to successfully bind. I don't have softwood so I have no idea about it. Now, some presses use heat to help bind the dust so they don't need as much pressure. I don't prefer that. One, it's a fire hazard. Two, your product isn't nearly as dense. Most log splitters don't even put out 70,000psi. So lets say you have an 8" cyl. in your garage. To run it you will need a pump that will run at least 4300psi. Most log splitters top out at 3000psi. What I'm trying to say is that it will take a large cylinder and a good pump. Without 3 phase electric, it will have to run off an engine because you can't get enough hp out of single phase. I had a lot of my design built off of an ruf briquette press. And, I found out they have their infeed prepressure cylinder patented. What confuses me is that some companies have a machines that work very similar to theirs. I don't know enough about patents to know what I could legally get away with. I'm not looking for a lawsuit. If I had access to a machine shop, I would build one. I have all the basic tools. Welder, plasma, etc., but it still would require a lot of machining. The best way would be to make your cylinder part of the pressure rod. To make a reasonable priced custom cylinder would require access to a shop. I have stepped away from it for the time being. I have built some smaller prototypes with scraps rigged on a log splitter. I can make it work. But, it's not in my budget right now. And once it's built, if you find you built your infeed say to small, I would be depressed. I don't really see that being a problem, because with a plc you can change all of your timing and pressure setpoints instantly. But, as we all know there are unforseeable circumstances. If you decide to build one, or just tinker with it, let me know. I have done a lot of the hydraulic math for different combinations and such. Besides, you might have an idea I haven't thought of. I know most of this post is a let down, but if I had more time and 10 grand in my pocket. I would be ordering in parts tommorrow. It was good to see this post again. So does anyone have an idea they would like to share. I'd like to talk some more about this. I think a person could create a market for briqs. It would take a year or 2 to get where you need it to be profitable. Ya gotta start somewhere.
