Elephant grass pellet mill, also known as miscanthus pellet machine. All belong to ring die pellet machines. Elephant grass pellet machine can make miscanthus into biomass fuel pellets or feed pellets as needed. The 6-12mm pellets made by the ring die pellet machine are better for fuel.
Elephant Grass commonly known as Miscanthus, is a high yielding energy crop that grows over 3 metres tall, resembles bamboo and produces a crop every year without the need for replanting. The rapid growth, low mineral content, and high biomass yield of Miscanthus increasingly make it a favourite choice as a biofuel, outperforming maize (corn) and other alternatives.
Miscanthus/Elephant Grass Properties
|Moisture content at harvest||20-50%|
|Bulk density at harvest(chopped)||70-100kg/m³|
|Calorific value(net)||~17Gj/tonne(dry basis)|
|Temperature which some sintering observed||600℃|
1. RICHI miscanthus and elephant grass pellet machine, the support bar and main shaft are forged together, keep uniform gap between roller and ring die, ensure high efficiency.
2. Increased forced feeding device, output increases 10-12%.
3. Forged bearing, long durability.
4. Pneumatic fast discharging gate, avoid burning the motor or damage the equipment.
5. Add oil when starting up, user can set the adding oil volume and period according to the case, avoid wrong operation hurting the machine. Stainless steel gate, long durability.
Firstly, Miscanthus can be used as animal bedding – production of horse bedding
Then, Miscanthus is considered to be a raw material for the paper industry, a source of fiber to be used in building materials.
And, Miscanthus is also widely used as a fiber material in geo-textiles. Its use as canes to support ornamental pot plants and the use of miscanthus ash arising from combustion processes as a fertilizer is also being done.
The most important one is miscanthus has 80-90% of the energy value of the initial biomass material and can be manufactured into pellets or briquettes used as a raw material for energy production and co-firing. Energy production alternatives that have been examined are co-combustion with coal and combustion in heating plants.
When elephant grass is harvested and baled in the field to increase density and maximize transport efficiency, it is then transported to the processing facility where it is chopped. elephant grass is chopped into fibers (25mm-35mm lengths) using a chopper or bale shredder then dried and pelleted.
The chopped miscanthus is further dried using a drier to allow processing to pellets. The required moisture content for pelleting is 10%-15%.
3. Grinding Processing
Before pelleting, the raw material must be reduced to an average particle size. For elephant grass, this will require two separate grinding operations. Bales will go through a chopper or bale shredder, then through a hammer mill.
Pellet formation takes place in the pellet mill where the feedstock is extruded through a ring die or flat die. As the pellets begin to extend outside the die, they are broken off with knives at a specified length. There are specialized pellet mill or pellet plant for elephant grass pellet production.
Cooling is necessary t stabilize, dry and firm the pellets. The counter-flow cooler is the most popular type in the industry. It pulls ambient air through a bed of pellets to remove moisture and heat through evaporative and convective cooling.
When the pelleting is complete, some amount of the material will have not formed pellets. These materials are called fines. Screening is necessary to separate this materials out. It is then sent back through the pellet mill. When the pelleting process is functioning correctly less than 3% of the material will be screen out.
After screening, pellets are bagged for residential sales or stored in bulk. For automatic packaging, pellet packing machine can service you. Pellets are conveyed to a bag-out bin where a scale measures the correct weight for each bag. The bags are then sealed and stacked on pallets.
1. Lower moisture content , which will be much more suitable for burning.
2. Lower ash content, which will reduce the risk of slag during burning.
3. Higher colorific value, which will generating more heat during burning.
4. Higher density which will be much more easy and convenient for transportation and storage.
5. Densified and uniform pellets makes the burning much more clear and stable.
