Step 1
Fill the bucket up about halfway with sawdust, fill the rest up with water. Allow the sawdust to soak for at least one hour, or until it begins to form a slurry.
Step 2
Scoop the sawdust into the brick press and follow the instructions for pressing. Every press is different, but you will likely either need to push down on a lever or tamp the press down tight yourself.
Step 3
Pull the compressed brick out of the press. Leave the brick out in the sunlight until it is completely dry. This will take different amounts of time based on your climate, but it could be several days. Place the bricks under an awning while drying if it begins to rain.
How to Make Wood Briquettes from Wood Raw Materials?
Wood briquette manufacturing process and briquette making machines are the two most important factors when making briquettes from wood chips, shavings and sawdust. In fact, the whole process can be divided into the following steps:
Makes Profits by Investing in Briquettes Productions from Wood Residues
Nowadays, there are plenty of wood residues produced every day in many places, so it is definitely profitable to make briquettes from wood chips, shavings, sawdust, etc due to the great market demands of wood briquettes around the world. According to users report, wood briquettes has many outstanding features over traditional fuelwood:
Lignin - Lignen
The secondary cell walls of wood and biomass are put together by a complex chemical called lignin (lignen). If you saw wood into powder and then melt the lignin in the powder, the lignin will again bind the powder together into solid wood. This is the idea used in binding sawdust into sawdust briquettes.
Starch Is Expensive
Sawdust can also be mixed with a starch paste and be bonded together as a briquette by pressing using simple briquette making presses. Such a briquette is very light, and it burns very fast, and produces a lot of smoke. To make it stable and last longer, just mix sawdust and charcoal fines at the ratio of 20/75 and add 5 - 6% starch binder.
Sawdust is Easily Available
Sawdust is the by-product you get after cutting lumber with a saw. Sawdust is composed of fine particles of wood which takes a long time to discompose. High concentration of sawdust in one area is considered an environmental problem.
Sawdust Briquettes
To get sawdust to bind together using its own lignin, you need to press the sawdust at such high pressure of 60 tonnes per cm². This is a very high pressure that the briquette comes out the orifice charred and steaming hot. It is this compression pressure that heats up the sawdust to a temperature of about 120°C.
Maintenance of Briquette Making Machine
The moving parts, rollers and dies will need to be replaced from time to time and this can turn out to be a big cost. And in addition you will need to pay for electricity that you will use in running the machine. The electricity can be about 7% the energy of the fuel briquettes made.
How to Make Charcoal Briquettes from Saw Dust?
The raw materials to make sawdust charcoal briquette is saw dust. In order to guarantee a larger productivity, the saw dust be below 1cm in size and the moisture content should be less than 12%. to guarantee a larger productivity.
Setting up Sawdust Charcoal Briquette Production Plant
Setting up a small scale charcoal briquette production line would be a great choice for those who desire to start charcoal briquette making business due to the low investment, easy operation and less maintenance. The basic sawdust charcoal briquette production process is as above listed, including crusing, drying, briquetting, carbornization.
