Biomass pellet mill is a kind of biomass pretreatment equipment. The raw materials mainly include agriculture and forestry processing waste such as sawdust, straw, rice husk, bark, bamboo, pipe, wheat bran, cotton stalk, alfalfa and so on.
Biomass Pellet Mill Raw Material
Application of Biomass Fuel
Pellet fuel is a new type of biological energy, it can be used replace wood, coal, fuel oil, liquefied petroleum gas, etc.
Heating and life for civil use： high fuel efficiency and convenient storage.
Biomass industry boiler: as the main fuel of industrial boiler, the pellet can be used instead of coal-fired so as to reduce atmospheric emission and pollution.
Generate electricity： the biomass pellet can be used as the fuel of thermal power generation.
Biomass Pellet Mill Working Principle
Raw material collection—-raw material grinding—-granulating molding—-cooling—-screening—-bagging
First of all, put the material (after preprocessing) into granulator. Next with the rotation and extrusion of the roller and pressure plate, material will turn into the mould hole along with the rotating. Then after a certain time pressure, the pellets will be reached the particle density and intensity and be squeezed outside the film hole. Finally,The cutter will be used to cut pellets into required length and pushed to the port of discharge.
- In the process of granulating, there is no need to add any chemicals or adhesive.
- Flat die pellet mill and ring die pellet machine working principle is different.
Biomass Pellet Mill Classification
According to different power, small biomass pellet mill can be classified into 4 types: electric pellet mill, diesel pellet mill, PTO pellet mill and gasoline pellet mill.
Electric Pellet Mill
Electric pellet mill is the most popular small pellet mills. Its capacity is 50-400kg/h. just as the relatively small capacity, easy to operating, movable, economical, and environmental friendly, the small electric pellet mill usually is bought by home, small farm, or small plant.
There are two types of electric pellet mill: R – type and D – type.
R-type Electric Pellet Mill
D-type Electric Pellet Mill
|ELECTRIC MOTOR WITH ENCLOSURE||ZLSP150C||5.5||60-110||105/125||1000x480x780|
Diesel Pellet Mill
Diesel pellet mill is usually used by people who are lack of electricity, especially in the fields or rural farms. Moreover, the cost of diesel oil is relatively lower.
Technical data of diesel pellet making machine:
PTO Pellet Mill
PTO (Power Taken Off) pellet mill is another popular small pellet mill for sale. It is suitable for people who have owned the tractor, because the mill is connected with the tractor and driven by the tractor.
|ZLSP120P||≥8 HP||40-80 kg/h||80/100 kg||900x540x900mm|
|90-180 lbs/h||175/220 lbs||35x21x35inch|
|ZLSP150P||≥10 HP||50-100 kg/h||90/110 kg||900x540x1020mm|
|ZLSP200P||≥15HP||80-120 kg/h||130/150 kg||1000x540x1020mm|
Gasoline Pellet Mill
Gasoline pellet mill is often for home use due to the small capacity. GEMCO can provide clients 2 types of gasoline pellet mill: ZLSP120Q and ZLSP150Q. It is very convenient and clean for residential heating and the lifespan of main part roller and die is 800-1000 hours. What’s more, pellet length and size can be designed according to customers’ needs.
