Straw Briquette Press Machine for Sale

Straw briquette press is a kind of machine that presses the crushed straw raw material into highly efficient and environmental friendly fuel or cattle feed. Through constant practice and improvement, GEMCO straw briquette press machine is gradually perfected. Now, it is highly automated with high capacity, low price, low power consumption, easy operation and no pollution. As a result, the briquette press machine for sale is widely used in rural areas to process different kinds of straws and stalks.

Briquette press machine working process

Crush the straw into less than 30mm long pieces, and control the moisture content at 15-25%. Then feed the raw material by a feeding conveyor into the briquette press machine. The straw raw material will be extruded by the briquette press into round blocks. Then, straw briquettes are cooled and packed into bags (moisture content less than 14%).

Straw briquette press machine significance

The briquettes made by straw briquette press can be 8-70mm in diameter, the length varies, and the density is 0.6-1ton/m³. The straw briquettes overcome the disadvantages of raw straw, like light weight, huge size and is easy to be influenced by external conditions. So the briquettes can meet the requirements of commercialization.
The straw briquettes are a new type of solid biomass fuel to replace coal in cooking, heating, power generation and some other fields. Compared to fossil fuel, biomass fuel is much less polluting to environment. Besides, biomass is easy to get, cheap and is rich in resources. As long as green plants grow every year, the biomass resources will never exhaust. Nowadays, as the coal, petroleum and other fossil fuels are in shortage, the wide utilization of biomass briquettes will play an important role in solving the energy problem for rural areas in many countries.
On the other hand, many kinds of straw like pasture or corn stalk can be made by the briquette press machine into briquettes to be used as cattle feed. After processing, the forage straw has good palatability, easy to transport, can be stored for a long time and never degenerate.

Features of straw briquette press machine

1. The briquette press machine for straw is highly automated, has high productivity, low price, low power consumption and easy to operate. As a result, less man power is needed for operating the machine.
2. It has strong adaptability to raw materials: whether the raw material is powder or 50mm in length (straw) with moisture content 5-30%, the briquette press machine can process it.
3. Both manual feeding and feeding machine can be used with it.

Straw briquettes technical parameters

• The volume of straw briquettes is just 1/30 of raw straw, and the density is 0.9-1.4ton/m³.
• The heat value is between 3500-5500kcal/kg.
• Ash content is around 5%, sulphur content<5%. Straw briquette is a kind solid fuel that has high volatile content.
• The combustion ratio of straw briquettes can be 95% or above. After combustion, the ash residue is a good source of high quality potash fertilizer that can be used to improve soil.

Straw was considered to be only useful for cattle feed. but with the emerging of briquette press machine, straw will become good resource for making solid biomass fuel.
