Customized For You

Complete Wood Pellet Production Line Processing Flow

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.

Raw Material Preparation

Raw Material Preparation

This is an optional section. If your raw material is a tree trunk, you need to use a peeler to peel the bark off the trunk and then use a splitter to split the stump, large branch, large log section, and hard wood to meet the requirements of the size of the material fed by the peeling machine.

Chipping Section

Chipping Section
Wood Chipping

This stage usually cuts logs or branches into pieces.The chipper is to fix several blades on the rotating disc surface. After the raw materials are fed into the chipper, they come into contact with the blades on the disc surface until all the raw materials are cut into small pieces.

Cleaning Section

Cleaning Section
Wood Pre-cleaning

As the wood 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.

Grinding Section

Grinding Section
Wood Crushing

The task at this stage is to further crush the wood into small wood sawdust.Only wood chips that meet the size requirements can be directly fed into the wood crusher, 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.

Conveyor Section

Conveyor Section
Wood Sawdust Transmission

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 sawdust drop down and also keep the environment clean .

Drying Section

Drying Section
Wood Sawdust Drying

For drying part, you can adjust the feeding speed, the rotating speed of the wood 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 pellets is 15%-17% . ( About how to adjust, our engineer will train your labors) Different capacity, and different capacity, the diameter and length of the drying machine is different.

Mixing Section
7
Mixing Section
Wood Sawdust Mixing

Whether producing single raw material pellets or mixed pellets, maintaining the consistency of raw materials is very important for wood 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 wood 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.

Pre-treatment Section
8
Pre-treatment Section
Pre-treatment for Top Pellets

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.

Pelletizing Section

Pelletizing Section
Press Wood Sawdust into Wood Pellets

The wood 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.

Cooling Section
10
Cooling Section
Pellet Cooling

The temperature of the biomass wood 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.

Automatic Packing System
11
Automatic Packing System
Pellet Packing

The qualified wood pellets are packed into plastic bag from 10 kg to 100 kg(Now more and more wood 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 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 pellets stored, especially in a warm environments. Be aware of the CO poisoning.)

 

Case About this

Typical Biomass Wood Pellet Line Turnkey Project

Name:The 12T/H Automatic Hemp Pellet Line
Country:America
Pellet Size:1-12mm
Main Material:Hemp
Total Power:977KW
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.

Project Summary

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.
