Regarding the wood pellet manufacturing equipment to be discussed in this topic, we usually call it a wood pellet machine or wood pellet mill, because this type of processing machinery came into being in response to the demand for wood pellets. However, with the continuous development of wood pellet making machine technology, wood pelletizers can be used to process various biomass pellets, mainly containing agricultural waste and forestry waste pellets, etc. Regarding its application, there will be more possibilities in the future. Nowadays, more people will name this equipment after the raw materials they use, such as: wood pellet machine, straw pellet machine, palm shell pellet machine, rice husk pellet machine, hay grass pellet machine, and other biomass wood pellet machine, etc. What these different raw materials have in common is: biomass waste.
Pelleting requires just the right combination of force, moisture, and temperature to achieve the perfect consistency. Our ability to achieve this perfect combination comes from configuring the right wood pellet manufacturing equipment in your wood pellet production line. RICHI pelleting solutions include everything for turning your waste resources into the perfect pellet, from the conditioning and extruding to drying and cooling and everything in between.
On the top of the wood pellet machine with a anti-caking bin . Inside the bin, there have two rollers for breaking the sawdust to avoid becoming cake . And the bin can keep wood pellet machine working more smoothly.
Because the wood sawdust is too light , so it is difficult to enter into the wood pelleting chamber , so we add a force feeder here to improve the efficiency of the wood pelleting process.
Optimized structure of the wood pelleting chamber ensures the uniformity of the material and maximizes the working potential of the wood pellet machine. Through the pressure between ring die and rollers, to make pellets. After pelleting , the wood pellets temperature is high about 70-80℃. And have 98% qualified pellets, 2% powder.
This is the 304 stainless steel ring die, it determines the final sizes of the feed! For the ring die, it has the following data: “d”, which refers to the diameter of the ring die ; “h”, which the the depth of the hole, or you can say the thickness of the hole. (d/h=compression ratio). The bigger the ”h” is, the long time is needed to press the materials out from the ring die, more power will be required to press them, so the final wood pellets will be harder. Because the“d”is fixed.
To control the length of final wood pellets , means through adjust the distance between cutter and ring die to get the different length of wood pellets.
When the pellet machine running , inside the pelletizing chamber ,the temperature is very high, and the moisture of sawdust enter into the pellet chamber is 15%-17% ,so it will produce a lot of steam . In order to keep the pellet machine good working, so we open a hole here, to connect with draught fan and cyclone, to exchange the steam inside the chamber and also reduce the temperature in the chamber.

Generally speaking, the wood pellet mill does not need to be equipped with a conditioner. If customers have special process and application requirements (such as processing grass, sawdust and other biomass as raw materials to feed animals), we can configure conditioners and customize the volume.
Due to the difference in electricity consumption in many countries, if clients have special electricity requirements on the machines, clients should pay the extra cost of electricity special needs.
The customers can choose the position of the motor, stainless steel pellet chamber door can be left-hinged or right hinged to suit the installation, the size of the feed screw, colour, etc., and many more are available depending on the wood pellet machine type.

Materials: Wood, crop stalk, peanut shell Wood Pellet Machine: MZLH320*1 Set Pellet Size: 6-8mm Wood Pellet Machine Price: 15000USD Project Cost: 130,000 USD Project Location: China
After drying, the material is conveyed to the biomass wood pellet
pressby the conveyor belt, and is fed by the leucorrhea feeding
equipment of the ring die biomass wood pellet making machine. The
biomass raw material is sent to the feeding chamber of the wood pellet
maker machine, in the distributor and scraper. Under the combined action
of the dies, it is evenly spread on the ring die, and then the material
is squeezed into the die hole. The material undergoes forming and shape
retention processes in the die hole.
Due to the increase in pressure in the ring die biomass wood pelletizier machine, the particles themselves deform and flow plastically, and generate a lot of heat under the action of friction, which causes the lignin contained in the raw materials to soften and increase the adhesion force. The combined action of cellulose makes the biomass gradually shape, and after a certain period of time, it is extruded in a cylindrical shape. The rotating cutter cuts the material to form a cylindrical shape and sends it out through the discharge port. This 400kg/h simple design biomass wood agricultural waste pellet line project does not add binder during the pelletizing process.
The biomass wood pellet production line project has strong profitability, quick return on investment, and more substantial follow-up profits.
①The scale of biomass wood pellet production.
If the scale of production is expanded, the number of equipment or production lines needs to be increased, and the total investment price will basically increase proportionally.
②Equipment model selection.
There are many types. When choosing, be sure to consult experts in biomass pelleting, or ask those wood pellet manufacturing equipment sales personnel for details, and pay special attention to economic indicators such as operating power consumption and maintenance costs.
③The characteristics of raw materials.
The processing technology of different raw materials is very different. The more difficult the type of pellets to process, the higher the investment cost of the biomass pellet production line.
① Different regions, different suppliers, different quality of pellet machine, and different prices. What you need is an absolutely reliable wood pellet mill manufacturer.
② The operating cost of the equipment is composed of worker wages, water and electricity fees, and wearing parts costs.
③ The management of the manufacturer, conscientious management personnel and skilled operators are the key to profit improvement.
Appropriately increasing investment in high-quality equipment can extend the service life of all accessories, reduce maintenance costs, and greatly increase production. This means that costs can be recovered in a short period of time, and profits and returns can be effectively increased.
