Complete Wood Pellet Plant Process

Usually a whole biomass pelletizing plant includes the following sections: raw materials crushing, drying, pelletizing, cooling and packing. The pelleting process varies from one raw material to another. Feel free to contact us for detailed pelletizing plan for your raw material. The following shows the complete biofuel pellet plant from raw wood (logs).

Debarking
If you use wood logs, timber or lumber as material for a wood pellet Plant, the first step is to debark logs to facilitate following steps of chipping and pulverization, therefore a wood barking machine is demanded.

Chipping
The step is to reduce size of the material from logs to wood chips with the universal size of about 2cm*2cm for pulverization.

Hammer Mill
Generally, hammer mill will be applied to crush chipps into smaller size of powder. However, a, integrated crusher can be used as well to decrease size of material for pelletization. Besides, two-time pulverizing may be considered as well to achieve a better pelletizing performance and ensure pellet mill will work stably.

Screening
A sifter is bound to use if the material you possess are beyond purity. The step is to cleanse and purify material with iron scraps, oversized impurities and alleviate damages as well as wear and tear to successive machines. Apart from the special sifting equipment, We will offer magnet tubes installed on conveyers and pre-pelletizing surge bin to multi-deironing metal foreigner matters.

Drying
The moisture content of material may remain higher than the required for pelletization. Therefore drying system is needed to reduce moisture content to about 12%-15% for pelletization.

Pelletizing
Flat die pellet machine is the best equipment for small scale pellet production (capacity 200~1000kg/hour), while for large-scale projects, ring die pellet machine is recommended.

Pellet mill is the most pivotal machine within a pellet plant. After being pelletized, material will be formed into granule shape or column/cylinder shape. For a larger scale plant, from time to time more than one wood pellet mill is needed, for example 4 or 6 tons pellets per hour and ABC Machinery is also excelling in providing large scale wood pellet plants combined with pellet mill assembly.

Dedusting System
Alongside pellet Plants, dedusting system is entitled to putting into practice with pelletizing system for reducing fly ash emissions. ABC Machinery adheres to the concept of environmental protection and purifying working environment. The cleaning system is composed of pulse dust collector, cyclone, pipeline and air lock.
ABC Machinery can provide clients with either manual dust collector and pneumatic pulse dust collector based upon different needs. Pulse dust collector is upgraded based upon Manual dust colletor but equipped with pneumatic system and metal cover so that manual force can be replaced by automatic dedusting system. Besides, the bags inside can be renewed with low costs and less maintenance.

Cooling
Newly produced biomass pellets are scolding due to the high temperature and high pressure during pelletizing. And a cooler will then be demanded to ensure the ensuing packaging and a longer storage time of pellets.

Sifting
Some powdery material may also flow from pellet mill with qualified pellets, in this regard, it is proved that a sieve will separate the small amount of disqualified mealy material from good pellets and also to qualify pellet packages.

Packaging & Slealing
Packing scale can be inquired with ABC Mahcinery too. Pellets can be weighed and packed in bags to facilitate pellet storage, transportation and marketing. The packing scale models are varied according to clients' demands. We can offer both small bag packing scale and bulk bag packing scale. And Packing machine offered by ABC Machinery is also integrated with sealing machine as a whole.
Wood pellet plants manufactured by ABC Machinery cover a wide range of pruduction yield from 0.5t/h to 12t/h, but for a smaller pellet plant with production output of less than 0.5t/h, it can be offered as well such as a biomass pellet project of 300kg/h or 200kg/h. Link to moveable pellet plant.

Electric Control System
Within a pellet plant, PLC electrical control system is mainly applied and ABC Machinery  can offer PLC system with lavishly professional experience. And the PLC cabinet can be printed on the surface with operator-oriented mimic diagram of pellet plant so that operators can get to know the entire system and master control procedures.

As we know, Regulations and provisions on electricity are different from one country to another. ABC Machinery has accumulated seasoned skills and abundant experience in connecting a variety of eletrical control system with pellet plant. Therefore, ABC Machinery can offer both standardized electrical system based upon China's use and the ones according to your demands to meet local standards for clients.
