Grass pellets have been customarily shaped for animal feed, though there has been a growing interest in grass pellets for the pellet fuel industry. Grass pellet mills can have diverse features to wood pellet mills. Grass pellet mills generally operate a higher speeds than biomass pellet mills. As grass has a lower density than biomass, and is easier to gelatinise, higher productivities owing to higher die speeds can also be achieved. In many cases flat die pellet mills are chosen for grass pellet mills. One of the reasons for this is because of the design of the flat die pellet mills, it is easier to feed grass into the mill. Flat die pellet mills work on a vertical design, by way of raw matter entering the mill mainly because of gravity. As grass is a low density material it is easier to get the grass into the compression chamber. As ring die pellet mills necessitate a feed system, it is harder to get adequate matter into the die at the required level. Also due to the perpendicular design of the ring die pellet mill, it is sometimes difficult to get the material to spread across the surface of the die.

Grass pellets have very diverse burning characteristics to biomass pellets for case. Grass pellets in general will manufacture a much higher ash content, in addition to possibly manufacture a clinker and slag formations. Another aspect of grass pellets that must be looking at before using in a pellet stove or boiler, is the increased risk of corrosion. During burning many grass pellets will generate at a higher temperature corrosive, chloride. Most pellet stoves and boilers are designed to purely burn premium wood pellets. If grass pellets are used in most pellet stoves as well as boilers, accelerated corrosion could destroy the unit within a few years. For more information on pellet stoves as well as boilers which can burn grass pellets. Hemp pellets are one of the few exceptions to grass pellets in terms of their combustion characteristics. Hemp is used in the production of paper, plastics, clothes, rope, oil in addition to even food. Hemp along with waste hemp residues after processing can also be used to make fuel pellets. Hemp fuel pellets, unlike other grass pellets make very little ash, no clinker or slag formations and a very low corrosion risk. These properties will see hemp pellets as key biomass fuel pellet in the future.

At PelHeat we produce small scale pellet machines which can be used to manufacture grass pellets. Pellet production can be a tricky process, it relies on consistent quality materials, in addition to the correct equipment along with set-up. One of the greatest comparisons is pellet construction is very similar to cooking.
