Log Briquette Maker

two type log briquette maker

Log briquette maker or stamping briquette machine is a kind of machine using the piston briquette theory to make the briquette.

High Pressure

The stamping energy comes from the big eccentric wheels which are connected with the motor by belt. In this running process, lots of energy stores and brings the pinch to stamp. The piston will push for 272 times every minute, makes an impact force up to 300 tons, which helps to make a high density biomass briquette, final biomass briquette density around 1-1.4 g/cm³. Compared, the density of the sawdust only have a density around 0.1 g/cm³.

More Than A Briquette Machine

The log briquette maker can produce briquette size between 6-80 mm, it does jobs not only a briquette machine does, also makes good pellet! Beside this, there are many advantages for you to choose a log briquette maker rather than a pellet machine, see the following:

A Comparison with pellet machine

log briquette maker Pellet Machine
Principle Ramjet Extrusion
Power consumption per ton ≤40 kW 80-120 kW
Continuous working time 7*24 hours Need to break each 3-4 days
Mold cost per ton ≤ USD 2.5 USD 3.5 – USD 4.8
Mold change time cost 10 Minutes 1 hour
Add oil Every month Every 2 hours
Briquette/Pellet size 6-80 mm 6-12 mm
Failure rate Low Need to be repaired each 5 days
Overload Seldom Always
Overload Solution Machine reverse Take 2-3 hours on repairing

The briquette length also can be adjusted which can even to one meter long!

Flexible die system

Components of flexible die system for log briquette maker

Flexible die system can rapidly transform your briquette size, allowing for easy changeover for small pellets or big briquettes, reduced stock holding. Further increasing the efficiency and productivity of your manufacturing operations.

Ten reasons why you should choose our log briquette maker

1. Can smoothly run for 7000 tons capacity without any fault;
2. The mold is made of special alloy steel, small and light, can keep using for 300-400 tons capacity;
3. With converter technique, feed speed adjustable, minimize the energy cost;
4. High-precision bearing bush, increase the smoothness of turning and impact resistance for the main shaft, highly extend the bearing working time;
5. Force oiling system for the piston and shaft, keep the machine running smoothly and extend these parts working time;
6. A variety of material adaptability, almost all the biomass materials can be briquette;
7. Three levels pre-press helps to make high quality briquette;
8. Can produce briquette from 8-85 mm only by changing the mold in an easy way;
9. Continuous work, Low energy consumption as well as low maintenance rate;
10. Simple and easy on operation.

Raw Materials

All the biomass and bio-waste.

Example: Crop stalks (including cornstalks cotton stalks ), grain shell, Rice husk, peanut shell and stalks, cotton stalks, sawdust, branch, bark, bean straw, bamboo powder, furfural residue(could be mixed used), wood scraps, forest harvesting slash, household refuse, scraps produced by paper making factory, living garbage, etc.

Material requirement

  • Size: less than 30 mm.
    This will make a low cost on the crusher as well as the energy cost of the crushing process.
  • Moisture: between 10-18%
    As the optimum moisture content for briquette purposes varies with the raw material,  from our experience the recommended moisture is from min. 10% to max. 18%. The ideal moisture content for most of the woods based material is 10-12%.

Binders? No!

Log briquette maker follows a stamping process that biomass is compressed under high pressure and high temperature. The briquette machine uses a large piston structure to make the biomass into briquettes that are of uniform composition. The self bonding of biomass to form a briquette involves the thermo-plastic flow of the biomass. The lignin content that occurs naturally in biomass is liberated under high pressure (up to 300 tons) and temperature (around 150-200C). Lignin serves as the glue in the briquetting process, thus binding, compressing the biomass to form into high density briquettes. During this process, no binder need to be used. And the output briquette is a type of clean and green fuel that is ideal for use in furnaces, boilers and open fires.

Crush ⇒ Drying⇒ Briquette

Crush: Though the log briquette maker has a rough material requirement on size, if your material is too big, it also needs to be crushed before briquetting, and remember, small raw material will help you to make high quality briquette;

Drying: A rotary dryer will be needed if the moisture of your raw material is too high;

Briquette: Choose the right log briquette maker model for your capacity, and one more thing you should know is the model YKSB-2 has twice the capacity as model YKSB-1, but only take 1.3 times electric cost!


Capacity (t/h) 1-1.3 2-2.6
Main Engine Power (kw) 45 75
Total Power (kw) 64.05 98.8
Power Consumption (kw/h) 50 65
 Space Requirement (m²) 16 18
Weight (t) 6.8 8.8
Size (mm) 3500*1950*2000 3500*2600*2000
Note: making pellet will cost less electric than making briquette.
