1. The working principle of wet wood chips biomass pellet processing equipment

The essence of wet wood chip pellet processing equipment is to "use mechanical high pressure as a driving force, with lignin (a natural binder) and water (an auxiliary bonding agent) as the bond, through a continuous process of 'crushing - extrusion - cutting - cooling' to transform loose wet wood chips into high-density, easily storable solid pellets." Its key advantage lies in its adaptability to wet materials. By optimizing die gaps, controlling frictional heat, and implementing a supporting cooling system, it avoids mold sticking and clogging caused by wet materials during processing. It also utilizes the moisture in the wet material to reduce extrusion resistance and lower equipment energy consumption.

2. Characteristics of wet wood chips biomass pellet processing equipment

(1)Precise machining accuracy: The main housing is made of high-quality steel, with uniform thickness and compact structure; it is carefully machined by imported CNC machining centers, with zero machining accuracy, providing stronger support for normal operation.

(2)Reliable lubrication system: The bearings and oil seals used in the transmission part are all made of high-precision bearings and wear-resistant and temperature-resistant fluororubber oil seals, and a special automatic lubrication system is added, with oil circulation cooling and automatic timed lubrication to ensure that the bearings are fully lubricated and the operation is safer and more reliable.

(3)Durable ring die: The ring die is made of precision and has a unique compression ratio design, which makes the product quality better and the service life of the ring die longer, minimizing the production cost.

(4)Continuous operation capability: The new generation of biomass pellet mill can achieve 24-hour continuous operation

3. Application scenarios of wet wood chips biomass pellet processing equipment

(1)Building materials industry: Wood chips can be used as raw materials for building materials and used to produce various boards and composite materials.

(2)Furniture factories: During the furniture manufacturing process, scraps and leftovers can be converted into wood chips through wet wood chip processing equipment. These pellets can be reused or used as fuel.

(3)Forestry and board mills: Wood waste generated in these places can be processed into wood chips for the production of biomass energy.

(4)Animal husbandry and feed industry: Wood chips can also be used as raw materials for feed pellets. After proper drying and processing, they can meet the needs of animal feed.

TONY Brand 24-30Ton/Hour Wet Wood Chips Pellet Manufacturing Plant can take wet wood chips, various types of wood - related biomass materials, such as wood pallets ,branches, wood logs, and wood shavings. After pretreatment and processing, wet wood chips is solidified into high - density wood pellet fuel.

Raw material advantages of wet wood chip pellet processing projects:

The core drawbacks of wet wood chips are their high moisture content, high transportation costs, and susceptibility to deterioration. Traditional disposal methods (landfill and incineration) require fees. This project effectively transforms these into raw material advantages:

1.Extremely low raw material costs, even negative costs

Wet wood chips are mostly waste from wood processing (furniture factories, plywood factories), forestry harvesting (tree branches/tailings), and building demolition (waste timber). Most companies have to pay for their removal and disposal. Project owners not only avoid purchasing these, but can even charge a "waste disposal fee" in some cases.

Compared to "dry wood chip pellet processing," wet wood chip raw material costs are directly reduced by over 80%, significantly reducing the total project cost.

2.Wide range of raw material sources and strong regional adaptability. 

As long as there are areas with wood processing, forestry, construction, and landscaping activities, there will be a stable supply of wet wood chips (such as furniture industry clusters, areas surrounding forest farms, and urban demolition sites). This eliminates reliance on a single raw material source and eliminates the "raw material competition" (dry wood chips must compete with industries like papermaking and wood-based panels, while wet wood chips have no other high-value uses), ensuring long-term raw material stability.

1. Environmental protection and sustainable development value

(1)Renewable energy attribute: The raw materials come from biomass waste such as wood chips, which are renewable resources. Replacing fossil fuels such as coal can reduce dependence on non-renewable energy and conform to the concept of circular economy

(2)Low carbon emission characteristics: The carbon dioxide emissions during combustion are much lower than those of fossil fuels, and the carbon absorbed by biomass during growth can offset the carbon released by combustion, achieving "carbon neutrality" and helping to slow down global climate change

(3)Solid waste resource utilization: Converting urban wood waste such as construction wood waste and garden branches into energy solves the environmental pollution problems caused by traditional incineration treatment, and has both biomass and sustainable development value. Ecological and social benefits

2. Energy utilization and economic advantages

(1)High calorific value and combustion efficiency: processed biomass pellets have high calorific value, long combustion time, and complete combustion. The energy conversion efficiency is comparable to that of wood chips with the same calorific value, which can meet the diverse needs of industrial production, power generation, and residential heating.

(2)Optimized storage and transportation costs: pellets have regular shape and high density, and the volume is only 1/5-1/3 of wood chips, which significantly reduces storage space occupation and transportation costs, making it suitable for large-scale distribution.

(3)High maturity of processing technology: small investment in production equipment, low energy consumption, and energy saving of 30%-50% in the drying process. The industry chain is well-equipped and economically feasible.
