Wood chips are wood that is made from forest harvesting, timber, processing and other residues and directional cultivation.Compared with directly burning wood and coal, wood pellet fuel is of high purity and does not contain other debris that does not generate heat, which will directly reduce costs for customers.
Our solutions come in a modular design so you can customize them to match your production process. At RICHI we focus on solutions that pay off, whether it's supplying the smallest spare part or serving as a long term partner.
As the wood chips raw materials are mainly forest felled materials, woodland miscellaneous irrigation materials, etc., it is necessary to collect the raw materials at this stage and remove the large wood blocks and debris through the roller screen.
The task at this stage is to further crush the wood chip raw material into small wood sawdust.Only wood chips that meet the size requirements can be directly fed into the hammer mill, or those that have passed the chipper and coarse crushing and require further fine powder. Due to the wide range of screen sizes on the hammer mill, it can produce particles of various sizes, so it is the most common choice for wood pellet manufacturers.
After crushing ,materials due to the existence of air circulation inside of hammer mill and can not drop down by gravity ,so we add a draught fan and cyclone with dust collector here, to provide the strong wind for breaking the circulation , in order to the final wood sawdust drop down and also keep the environment clean.
For drying part, you can adjust the feeding speed, the rotating speed of the drying machine, and the inlet air temperature to adjust and to get the required moisture to make wood pellets. And the suitable moisture to make wood chip pellets is 15%-17% . ( About how to adjust, our engineer will train your labors) Different capacity, the diameter and length of the drying machine is different.
Whether producing single raw material pellets or mixed pellets, maintaining the consistency of raw materials is very important for pellet production plants. After the raw materials are grinded and dried, binder(vegetable oil, molasses, starch, gluten, dried lees, rapeseed cake, etc.) need to be added，so it is necessary to use a mixer machine. After mixing, the raw materials are mixed more fully and evenly, and then sent to the pellet making machine.
This is an optional section, only a few customers who use special processes will choose. If your raw materials contain enough natural lignin to be glued together,you do not need additives and can completely ignore this section.
After the raw materials are thoroughly mixed, water and steam need to be added to make the pellets. These additives can help improve the working efficiency of the pellet mill machine.
The wood chip pellet making machine is the heart of the wood pellet production line. The pellet machine is widely used for pelletizing wood, straw and other biomass energy. The output ranges from 1 to 10 tons / hour. The biomass wood pellet machine adopts Swedish SKF bearings and Siemens motors, which can fully guarantee the wood pellet equipment capacity and stable operation.
The temperature of the biomass wood chip pellets after granulation is as high as 80-98 degrees, the structure is relatively loose, and it is easy to break. It must pass through a counter-flow cooling system and be cooled to room temperature before entering the warehouse.
The forming rate of wood chip pellets is around 98% , so there are still have 2% powder in pellets, by screening, sort out all the powders from pellets.
The qualified wood chip pellets are packed into plastic bag from 10kg to 100kg(Now more and more biomass pellet processing plant choose tonnage scales).Then use thermoplastic sealing machine to sew, these can make the pellets dry and water-proof.To extend the wood chip pellets storage time .(The pellets should be kept from the direct sunlight, which may higher the storage temperature and increase the chance of fine percentage.The pellets should be kept in a well ventilated place because monoxide gas may be released from the wood chip pellets stored, especially in a warm environments. Be aware of the CO poisoning.)
PLC is designed according to the requirement of the customer. It can also control automation level.Our PLC is provided by the top international brands in the industrial automation field such as Siemens, Schneider and Delta.
Name:The 12T/H Automatic Hemp Pellet Line
Main Machines:ForageHammer Mill*90KW,Hemp Mixer*1000KG/BATCH,Hemp Pellet Machine*160KW,Cooling Machine,Crumbler Machine, Screen Machine,Automatic Packing Machine and other equipment.
The hemp pellet mills in this project were developed for top throughput capacities in compound feed pelleting, and can process even difficult-to-press raw materials which have a high fat or fiber content. The machine sets new standards in terms of efficiency and performance: substantially lower energy consumption in comparison to conventional pellet mills, production capacities of up to 20 t/h, motor ratings of 220 or 260 kW and a customer-oriented design are just some of the advantages of this RICHI machine. However, thanks to the extremely compact design, the machine takes up very little space(workshop size:16m*7m*7.5m)– it delivers twice as much capacity with the same footprint as conventional pellet mills.
Name: 2T/H Automatic Wood Pellet Line
Main Material: 50% moisture wood chips , 50% moisture sawdust
Main Machines:Wood Chipper,Wood Hammer Mill Crusher, Shifter, Wood Dryer, Storage Bin, Pellet Machine, Cooler, Auto-packing Machine and other auxiliary equipment.
In this project cooperation, exquisite process design and strong production team are very critical factors to impress customers. The final biomass pellets of the project are mainly used for export, and have high quality requirements. Environmental protection and energy saving are integrated into the design of the plan. The dust removal system runs through the entire production link, so as to achieve zero pollution and zero emissions, and meet the local regulations of customers.
