Grass pellet machine

Grass is available in farmland, lawn and residential green belt. It a common material to make feed pellets and biofuel pellets. Grass pellet making machine is a specialized equipment for making pellets from grass and other biomass materials.

Why you should make grass pellet fuel

  • As grass has lower density than wood material, it causes less wear and tear to grass pellet making machine. And the grass pelletizer can work at higher speed and productivity.
  • Grass is more economical and available than other wood materials.
  • Grass pellets fuel can be used in pellet stove, furnace, water heater, industrial boiler and electric plant. They boast low carbon emission and high combustion rate.
  • The BTUs of grass pellets is the same as wood pellets, but the ash residue is a little more than wood pellets. So we recommend you to mix wood pellets with grass pellets to reduce the ash residue.
  • As we know, the water content in raw materials for making wood pellets should be lowered to 10%-18%. Grass materials are more lose, which can be dried by air on the field, and save a great deal of cost compared with wood.
  • Grass is more convenient to store and transport than bulky grass materials, for it has less volume and contains less dusts.
  • Making grass pellet fuel has become a prevalent business all over the world. Biomass pellets are energy-efficient, eco-friendly and economical, which has receive supports from governments and NGOs.

How to make grass pellet fuel

Making high quality grass pellet fuel takes the following steps. The major equipment is a grass pellet making machine.

grass pellets making process

Dry grass materials

Mow the grass and lay them in an open place. Keep the layer thin and let them dried by the sun and wind. Limit the moisture content to between 10% and 18%.

Preheat the grass pellet making machine

Start the grass pellet making machine, and wait a few minutes for preheat, so that it can melt sway the lignin in grass and make it easier to combine.

Collect the produced grass pellets

Before feeding grass materials into the hopper of grass pellet making machine, you need put a container under the outlet to collect the produced pellets.

Check the pelletizing effect

Inspect the quality of grass pellets. If they are crumbly, this indicate the raw materials are too dry. You need to add water to them. If the grass pellets are pasty, this shows the moisture content in materials is too high. You need dry them further.

Cool the grass pellets

Don’t pack the grass pellets right after pelletizing. Leave them in good ventilation status until they get cooled.

Packing the grass pellets

Collect the unused grass pellets and package them in bags for further use or sale. These grass pellets are useful in cooking, heating and power generation, etc.

Choose high-efficiency grass pellet making machine

A high-efficiency grass pellet making machine can help you make grass pellets at high speed and low cost, and improve the molding rate and lower the material waste as much as possible. Our grass pellet making machine can be driven by electric motor, diesel engine, gasoline engine, and PTO (power take off). Their production capacity are from 100 to 400 kg/h.

You don’t need to add any binder to the materials, but some binders may improve the pelletizing effect. Besides, you can also mix different biomass materials together to make pellets with different properties.
