Richi Machinery is an international pelletizing technology group and a globally supplier of sawdust pellet plants, sawdust pellet making equipment, and services for a broad range of industries. RICHI sawdust pellet making machine is designed to provide biomass pellets producers with a way to maximize production capacity while also achieving the best quality biofuel pellets under the safest possible conditions.
The sawdust pellet machine is the key equipment of the sawdust pellet production line. Richi Machinery is one step ahead in the sector by designing a special machine for biomass wood fuel pelleting with its R&D studies on the biomass sawdust pellet mill, which is the main machine of the wood pelleting process.
Biomass sawdust is the name given for all non-fossilized biological material. Biomass is an important energy source as it constitutes the fourth largest energy source in the world. In many developed countries, bioenergy is seen as the primary energy source of the future.
Biomass processing is a growing industry due to the increasing importance of renewable energy. Sawdust bioenergy values of biofuel materials, such as agricultural products and forest residues, after thickening processes such as pelleting are becoming commonly used fuels.
A quality sawdust pellet fuel made by biomass pellet machine can be created when two or more agricultural wastes are mixed in appropriate proportions and pelleted by determining their burning characteristics and energy values.
The raw materials for biomass sawdust include dedicated energy resources such as trees, crops, grasses, and algae. Various waste streams such as agricultural waste, human and animal waste, forest product and paper mill waste, and municipal solid waste can also be collected as biomass sources. Furthermore, biomass sawdust sources can be used to produce higher value biomass fuels in the form of solids (e.g., wood sawdust pellets).
1. The sawdust pellet machine ring die and roller use high strength forgings, automatic gun-drill drilling and vacuum heat treatment. The ring die service time﹥500 hours.
2. The sawdust pellet mill has high gear transmission efficiency, large transmission torque, large roller friction, production is increased by 15%.
3. Mandatory feeding assures uniformity.
4. The sawdust pellet maker adopts design of spiral feeding plate to ensure uniform intake of sawdust pellets and balanced extruding stress.
5. Easily operated control cabinets. Sawust pellet press machine automatic control system is connected to central control room.
6. Sawdust pellet making machine has intelligent system including working reports, working time, oil temperature alarm and lubricant replacement reminding.
RICHI sawdust pellet press machines are constructed from the most durable materials to insure proper die roll support and are energy efficient due to their single reduction gear system. Die casings and housings are lined with stainless steel and the main shaft is machined to precision tolerances and then heat treated to reduce wear and tear and increase the lifetime of your sawdust pellet mill equipment.
Additionally, the cartridge assembly of sawdust pellet making machine is designed to make die changes fast, easy and safe, saving the operation from unnecessary down-time.
The constant exposure to extreme pressure, fluctuations in temperature and abrasion that comes along with shaping raw plant based materials into saw pellets, requires precision die design. Richi Machinery sawdust pellet makers are strong and dependable, built specifically to withstand these tough conditions.

To process sawdust pellets, sawdust pellet mills are not enough, and a lot of sawdust pellet line equipment is needed. And these equipment will jointly form the finished sawdust pellet production line or sawdust pellet factory. Every sawdust pellet processing line needs to be designed, from the pellet production process to the layout design, and even the design of some basic buildings, which is a very complicated process.
How to make sawdust pellets? How to make wood pellets from sawdust? Let's take a 4.5 ton per hour wood sawdust pellet production line projet as an example to show you the sawdust pellet making process we have customized for our customer.
Use sawdust as the main raw materials. To ensure sufficient raw material supplement and continuous production, the storage area should be around 500 square meters. You are suggested to prepare 500~600 tons of sawdust, which can ensure at least 15 days of sawdust pellet production.
The ceiling of raw material warehouse should be able to resistant rain, lighting and wind. Set the production area at least 50 meters away from the living area, 30 meters away from the highway and power transformer. Besides, isolation measure and fire prevention facilities are also necessary, in order to ensure production safety.
Biomass pelletizing has strict requirements on the moisture content of raw materials. After screening, the saw dust will be sent to roller dryer by spiral conveyor. In the wood sawdust dryer machine, the sawdust can be dried to preset moisture content through hot air.
Sawdust pelletizer is the key equipment of the complete pellet production line. In this system, we adopt 3 sets of ring die wood pellet press for making pellets from sawdust which is featured of stable operation. The capacity of each set can reach 1.5 ton per hour.
This sawdust pellet mill machine can process wood sawdust, corn stalk, haulm, cotton stalks, peanut shells and many other biomass materials. The density of finished pellets can reach 1.0~1.3t/ m3.
When discharging from the biomass sawdust pallet making machine, the temperature is around 80~90 ℃. The structure is relatively loose and easy to be broken. Through counter flow cooling system, the sawdust pellets will be cooled to room temperature and become tight and durable. Then, they can be packaged in bags or be conveyed to storage silo. Except cooling fan, the cooling system is also designed with cyclone separator which is used to separate the powder from the pellets and send the powder back to the front pelletizing procedure.
After cooling, screening system is needed to filter out broken pellets, so that to ensure the quality of final products. The broken pellets will also be sent to the front pelleting process.
Before packaging, the sawdust pellets will be screened again for recycling the fines. And then the pellets will be packaged. For domestic users, the pellets are preferred to be packed into bags with the sizes of 12, 15, or 20 kg. While for exporting, the pellets are usually shipped in one tone bags or in bulk which are usually wrapped in plastic to keep the moisture out. Compare with the large bulks or bags, the small bags are better for the pellets because the pellets are subject to less abrasion during delivery.
During summer, the production of sawdust pellets probably exceeds the demand and the pellets may have to be stored for several months. The storage facility should bee constructed of high concrete side walls that can withstand the pressure of the pellets. As stated, pellets easily disintegrate once they get wet, so it is very important that the building is water-tight, to prevent rain or condensation.
Biomass wood sawdust pellets are classified according to their physical and chemical properties. These properties affect the possibilities of pellet use in energy conversion technologies. For instance, a comparatively low amount of dust and ash in the pellet is an important factor for small heating systems, while larger power systems can cope with higher amounts of dust and ash. Other important parameters include durability, surface smoothness, and resistance to swelling.
