2.2-3 ton/h Biomass Wood Pellet Mill JWZL-688


The powdered wood chips, straw, bark, and other materials in the pre-pelleted bin are transferred into the inclined trough by the feeding winch. The material enters the pressing chamber through the forced feeder and is fed by the feeding scraper into the two pressing zones in the ring die. Influenced by the high-speed rotation of the ring mold, the material is conveyed between the ring mold and the pressure roller. Under the strong extrusion of the ring mold and the pressure roller, the material is gradually compacted and shaped in the mold holes. As the extrusion between the die rollers is continuous, the shaped material is continuously discharged from the die holes in the form of columns and then cut by the cutter into granules of the required length to enter the next.

Brief of JWZL-688

● The Pellet mill is the most key equipment during the entire production process. This machine determines the output of the whole process, and the JWZL-688 pellet mill is one of the most efficient and stable machines. JWZL-688 pellet mill has built a high reputation for Kingwood for its smooth operation and the high value it creates for its customers.

● The technical means used in the JWZL-688 are:
(a) reinforced frequency-controlled feeding;
(b) forced feeding;
(c) hoop-type ring mold;
(d) all imported bearings and oil seals in the transmission box;
(e) off-board thin oil lubrication and cooling circulation system (optional), which integrates cooling, filtering and oil cut-off alarm, to forcibly lubricate the main bearings;
(f) serpentine spring coupling with large compensation capacity to transmit power, etc.

Advantage of JWZL-688
● The main drive adopts a high-precision gear drive, and the ring die adopts the quick-release clamping type. The overall efficiency is about 20% higher than the relative belt drive type.
● The transmission part of the whole machine uses high-quality imported bearings and oil seals to ensure efficient, stable, and low-noise transmission.
● JWZL-688 contains a more advanced level of serpentine spring coupling, with a novel structure, compact, safe, low failure, and other properties.
● JWZL-688 equips with a non-stop refueling system and an air-cooling system, which provides high efficiency, low energy consumption, smooth operation, and stable and reliable granule quality.

Industry Knowledge

What types of biomass materials can be used with the JWZL-688 pellet mill?

Are you looking for a reliable and efficient pellet mill for processing biomass materials? Look no further because the JWZL-688 pellet mill is here to meet your needs. With its advanced technology and versatile capabilities, this pellet mill is capable of processing a wide range of biomass materials. 
Amongst the most prevalent biomass materials employed in conjunction with the JWZL-688 pellet mill, we find the ever-familiar entities of wood chips and sawdust. These readily available substances, widely embraced by the pellet production industry, undergo a seamless transformation into pellets of the utmost quality, rendering them a veritable gem for employment as fuel or feedstock.
Agricultural residues, ranging from the likes of straw, corn stalks, rice husks, and sugarcane bagasse, lend themselves remarkably well to the efficacious processing capabilities of the JWZL-688 pellet mill. These bountiful materials, often deemed waste, can be imbued with newfound value through the judicious utilization of the appropriate equipment. By harnessing the latent potential of agricultural residues, one can contribute commendably towards the promotion of sustainable farming practices, while concurrently combating wastage.
Delving further, we encounter the realm of energy crops, wherein the likes of switchgrass, miscanthus, and willow reign supreme. These crops, meticulously cultivated for the explicit purpose of biomass production, boast an incredibly high energy content. Furthermore, they thrive even amidst the most desolate stretches of land, thus emerging as an ideal choice for the production of pellets. The JWZL-688 pellet mill, with its seamless processing capabilities, ensures the optimal utilization of energy crops, empowering you to unlock the fullest potential of these invaluable resources.
Within the purview of forestry operations and forest management activities, the generation of forestry residues, including the likes of bark, branches, and leaves, stands as an inevitability. Instead of allowing these remnants to languish in oblivion, the JWZL-688 pellet mill presents an exceptional opportunity to transmute them into biomass pellets of immense utility. Through the astute employment of forestry residues, one can actively contribute to the mitigation of environmental impact, harnessing the latent potential of hitherto untapped biomass sources.
In addition to the aforementioned materials, it is worth highlighting that the JWZL-688 pellet mill constitutes a versatile force, capable of seamlessly processing an extensive assortment of other biomass materials. This encompasses but is not confined to, the likes of nut shells, coconut husks, straw pellets, and even select categories of industrial waste. The sheer adaptability inherent in this pellet mill opens up a realm of endless possibilities within the domain of biomass pellet production.
