1,000 KG/H wood pellet line
From: EP Machinery
Briefly Introduction Wood Pellet Line:
1. Raw material:
Wood pellets can be made from sawdust, wood shavings, wood chips or wood logs, any wood wastes or biomass straws, stalks, etc.
2. Involved processes:
Depending on the input materials, which are cereal straws, wood materials, etc.So before the pelleting press, a product with a granular size of approx. 5 mm and a residual moisture content of approx. 15 % is required.
The mainly processes are: Wood Crushing / Hammer mill (if the raw material size is larger than 5 mm), Drying Machine(if the raw material contains too much moisture), Pelletizing, Cooling and Conveyors, Electric Cabinet. The whole process is highly automatically controlled.
3. Production capacity:
1,000 kgs per hour is available.
4. Highlight of our equipments
1) Reliable continuous operation
2) Low energy consumption
3) Low maintenance cost
Part A: Hammer mill & Wood crusher
Clients can use any kinds of agro-wastes to make biomass pellets, such as wood sawdust, branches, prunings, straw, stalks, grass, etc.
But for different size of biomass materials, hammer mill or wood crusher can be optional. If the diameter of biomass materials is less than 50 mm, clients should choose hammer mill. If the diameter is 50-250 mm, client should choose wood crusher. For hammer mill and wood crusher, all of their final crushed size is less than 5 mm, which are suitable for making pellets.
Part B: Dryer
Raw materials which contents humidity above 20%, you need to install a dryer before further processing. And the best Humidity Content is 12%-15%.
Part C: Granulator/Pellet press
Flat die pellet mills are generally used for pellet production on a small to medium scale. The HSKL series of flat die pellet mills below can process a wide range of biomass materials, for a range of applications. These include wood, straws, grasses and other biomass residues.
Part D: Cooler and Screener
Cooler is the machine to screen and cool the finished pellets by connecting the pellet machine with cooler together. After screening and cooling by the cooler, the pure pellets will come out without any dust and temperature.
Part E: Screw Conveyor
The conveyor is used to convey particle materials and small lumpy materials to the next equipment in the process. The length and the shape of conveyor can be adjusted differently according to customers’ requirements. This conveyor can save labour cost for moving the materials.
Part F: Electric Cabinet
The electric cabinet is used for controlling the whole plant electricity supplying in the production line. It is more humanized.
Part G: Rotary Screener
The rotary screener is used for screening some iron materials and mess in the biomass materaisl. It purify the raw materials and ensure you use the clean materials to make pellets.
