How To Make Grass Pellets For Fuel

Grass As Raw Material

Generally speaking, grass is divided into dry grass and green grass. Our common grass is generally used as silage for animals, of course, it can also be made into fuel pellets. Hay is more suitable for making fuel pellets. Of course, green grass can also be used. The water needs to be removed first, and some can be dried before pelleting.

How to make grass pellets for fuel

For making grass pellets for fuel, the farmer requires a complete pellet plant for this procedure. Freshly harvested grass is turned into pellets by undergoing the following procedure:

First the grass is dried. Fresh grass contains a lot of moisture. Its moisture content is 75%. However, for pellet production the moisture content has to be 10%. Hence, the grass has to be dried. It is dried by leaving it under the sun for an hour or two.

The dry grass is crushed. The grass is usually 3 meters tall and cannot be handled while that tall. It has to be crushed into smaller sizes no longer than the hole diameter of pellet mills. The grass is crushed using a cutting machine or using a farm knife to cut it into smaller pieces manually. If the grass is a lot simply use the crushing machine which makes the work easier and faster.

Pelleting. This is entirely done by the pellet mills. The farmer fills the crushed grass into the pellet mill. The pellet mill then mixes the crushed grass and molds it into small pellets. The better the pellet mill, the better the pellets. So when purchasing a pellet mill looks out for quality. It is advisable to purchase pellet mills from known brands and one that has a proven track record of making quality grass pellets.

Cooling the pellets. The pelleting process is exothermic. It involves a lot of friction hence producing a lot of heat. Hence, the produced pellets are hot and soft. The pellets need to be cooled in order to harden; this increases their durability. Running cold water over the pellets cools them. Simply place the pellets in a container and run cold tap water to cool them.

Packaging and storage. After cooling, the farmer can put the pellets in bags then store in a cool and dry place. The pellets are high density hence making storage and transportation easy.

Advantages of grass fuel pellets

As an eco-friendly resource, grass pellet has high combustion efficiency.

Burning grass pellets causes no pollution problems and produces almost the same amount of heat as wood pellets.

Grass pellets fuel is much better for the environment because it emits less greenhouse gases than coal, oil and natural gas.

We don’t need to worry about the supply of grass, because the grass is perennial and it can grow all the year round. Furthermore, grass does not need to be fertilized or watered and it can be grown even on poor land.

Because of the rising cost of fossil fuels and the shortage of energy resource, grass pellets are becoming more and more popular.

The most important point for grass pellets is that they can be made at home completely.

Forming the grass into pellets allows the materials to be handled and stored easily, transported economically, and burned efficiently.

The grass is soft and light, so that the drying process can take place in the field, which can reduce the production cost.

Tips & Warnings

Moisture content is crucial for the quality of the exited pellets. Good pellets are hard and shiny.

There are many other raw materials suitable for making pellets except grass, such as cardboard, junk mail, crop waste or leaves.

Before feeding into the pellet mill, the biomass must be crushed into small pieces, so a hammer mill or crusher is usually needed.

The pelletizing process generates exhaust and dust so you are suggested to use the pellet mill outside the room.

It is safe to wear eyewear and protective clothing during the pelletizing.
