wood pellet mill
Wood pellet mill is the key component in a complete wood pellet plant. It is mostly used to process wood materials like wood chips, sawdust, shaving, tree branches, logs, wooden pallets and so on, it is a kind of high efficiency wood pellet maker. Also, it can process other raw materials like palm fiber, sugarcane bagasse, peanut shell, corn stalk, wheat straw and many other agro-wastes.
As a raw material; wood (hard and soft woods), wood chips, sawdust, hull, tree branches, tree leaves and similar forest residues are used.
- Hardwoods; Mahogany, Walnut, Oak, Ash-tree, Birch, Maple, Cherry-tree, Beech etc.
- Softwoods; Pine, Larch, Picea etc.

Wood pellet machine is an extrusion equipment for making cylindrical pellets. It is mainly used in biomass fuel, crude fiber feed, granular activated carbon, carburizer and other industries. The specific uses are as follows.
As a wood pellet machinery supplier, Richi Machinery manufactures and supplies the key wood pellet processing machine and othe processing machine in the wood pellet production line. JASTEC wood waste pellet machine can be used for wood and various agricultural and forestry wastes, which is applicable for all kinds of biomass materials. We also offer single machines for the production of biomass wood pellets, solid biofuel, and waste pellets.
- Biomass fuel industry: Various wood waste, straw, rice husks, peanut shells, palm shells, corn cobs, waste cloth and other materials can be compressed and pelletized as environmentally friendly fuel pellets to replace coal.
- Crude fiber feed industry: The wood pellet machine can also be used as a professional equipment for making crude fiber pellets (straw, hay, etc.). It has large torque and can withstand high pressure. It is easier to use it to make crude fiber feed pellets.
- Granular activated carbon and carburizer industry: The raw materials of carburizer and activated carbon have the same properties, both are similar to carbon powder. Adding certain additives or moisture can be easily formed by pressing with a wood pellet mill.

The global warming impact, the increasing prices of fossil fuel, and the need to produce thermal and electrical energy stimulated the creation of an industry leaning toward energy production by renewable sources. Biomass is a widespread renewable source to provide energy demand in terms of electricity and heat. Of course, wood pellets have many other uses, such as cat litter, organic fertilizer, etc.
Wood is by far one of the oldest and most abundant types of biomass raw materials. In addition to cord word, other types of forest products residues such as tree tops, branches, bark, logging slash, and saw mill waste can be used as sources of biomass energy.
Pellets processed by biomass pellet mills can be used in many industries and are suitable for many raw materials, but for now, biomass pellets are mainly used to process fuel pellets.
The volume after molding is 1/30 ~ 40 of the volume of the raw material, the specific gravity is 10 ~ 15 times (the density is 0.8 ~ 1.4), the calorific value can reach 3400 ~ 6000 kcal, and it is a high-volatile solid fuel.
Technical Features Of Wood Pellet Mill
The wood pellet mill is mainly composed of a feed port, a compression chamber, a discharge port and an electrical control system. Among them, the compression chamber is the core part of the granulator. It is composed of multiple compression molds and can compress waste wood materials such as sawdust into pellets. The quality and quantity of compression molds are important factors affecting the performance of the wood pellet mill machine.
- The wood pellet mill main shaft system uses double support structure without shake to offer more extrusion force from ring die;
- The wood waste pellet machine control device of ring die and roller is external to realize gap adjustment without stop-working;
- The wood pellet machine rollers use circulating water cooling, realizing lower temperature and longer service time of bearings, and lower oil consumption;
- The bearings of main shaft and roller with temperature measuring device, which can monitor the working status of wood pellet making bearings;
- The wood pellet maker key components like main shaft, driving wheels and gears are made of high strength forged alloy steel. Gears are processed by high precision gear grinding machine;
- The wood pelletizer driving system uses imported bearings to ensure the reliability and long service time of the equipment;

The prospect of Wood Pellet Mill
The wood pellet mill machine is a new type of environmentally friendly equipment that uses wood energy to produce. It can convert agricultural and forestry wastes such as sawdust, straw, rice husks, etc. into wood pellet fuel. The use of wood pellet machines can not only solve the problem of agricultural and forestry waste disposal, but also bring great convenience to our lives.
The primary working principle of the wood pellet making machine is to compress agricultural and forestry waste through high temperature to form pellet fuel with high density and high combustion value.
Compared with traditional fuel and coal, this new type of fuel has higher combustion efficiency and generates greater heat. It is worth noting that during its combustion process, the emission of pollutants is extremely low, which is beneficial to environmental protection.
In the current society, energy shortage and environmental pollution problems are becoming increasingly serious, and the application of biomass pellet machines has great prospects. Its use can improve energy utilization and reduce the impact of waste on the environment. It can also reduce the company's energy costs and improve production efficiency.
1.How Are Wood Pellets Produced By Complete Wood Pellet mill Plant?
- In global market, wood pellets are mostly produced from sawdust, wood shavings and other woody byproducts. Traditionally, wood pellet production line units are located on or nearby sawmills and other wood processing sites, representing complementary outlet for these wood pellet manufacturing plants. In this context, a first crucial step for wood pellet producers consists of grinding and drying the moist wood residues.
- The energy needed for this is mainly made available by the burning of bark or any low quality wood, which likewise accumulates on site. In many cases, not only is heat produced by burning the bark, but also electricity that can be optimally used to run unit. After the wood waste is dried, it is fed into a biomass wood pellet mill. Within the wood pellet maker, dry woody materials are squeezed through a die with holes of the required size (normally 6 mm diameter, sometimes 8 mm or larger) called a matrix.
- The high pressure of the wood pellet pressing machine causes the temperature of the wood to increase greatly, causing the surface to plasticise slightly to form a natural "glue" that binds the wood pellet together as it cools. To facilitate the wood pellet pressing process and improve quality parameters, small quantities (max. 2%) of natural binder such as starch can be added, but no glues enter the composition of wood pellets.
- Newly compressed pellets are now ready to be cooled and sieved to remove any residual particles. Finally, wood pellets can be stored and/or bagged by wood pellet packing machine prior being delivered to end consumers.

2.Ring die pellet mill or flat die pellet mill, which is better?

Although we also design and manufacture flat die wood pelletizers, with the continuous improvement of the processing technology of wood pellets, the characteristics of the flat die wood pellet manufacturing equipoment are not as good as the absolute advantages of the ring die wood pellet press machine.
As a professional wood pellet mill manufacturer, we must sincerely tell everyone that the wood granulator technology must move forward, and the ring die wood granulator is the final trend. Considering the quality of equipment, durability, maintenance cost, and quality of finished pellets and other aspects, if the output you need allows, try to choose a ring die wood pelleting machine.
Usually you can see many flat die wood pellet makers on the Internet, which will confuse many customers who are in the wood pellet processing industry for the first time. In fact, well-known and professional wood pellet mill manufacturers do not recommend purchasing flat die pellet mills for wood and biomass pellets, because the quality of the actual processed pellets is not good, and the output cannot keep up.
When you browse the official websites of groups such as CPM and Buhler, you can easily see that there is only a ring die pellet mill machine (which can also be a wood pellet extruder or feed pellet extruder), and there will never be a flat die biomass wood pellet making machine.
