About commercial wood pellet mill

This video shows how a commercial wood pellet mill works. The crushed raw materials are dropped into the pelletizer feeder and enter the interior of the pelletizing chamber hrough the feeder. Inside the pelletizing chamber, the materials are transformed into compact wood pellets under the extrusion of the ring die and pressure rollers.

Wood pellet mill can be divided into big wood pellet mill and small wood pellet mill according to the capacity. Both of them have the same working principle and structure, but there is a big difference in output, size, power consumption and price, and the application scope is naturally different.

Small wood pellet mill is small in size, easy to operate, time-saving and labor-saving, suitable for small wood pellet plant or farm use.

The big wood pellet mill has strong applicability and high output, which is suitable for medium and large scale biomass pellet plant. If you are planning to build a wood pellet production line or your production demand is relatively large, then we recommend that you can directly purchase a large wood pellet mill machine.

advantages of commercial wood pellet mill

We already know that wood chip pellet maker is a machine that presses wood, logs, sawdust, and other materials into 6-12mm wood pellets. Then what does it consist of? I will introduce you the main parts of the wood pellet machine below.

Structure of commercial wood pellet mill

As we mentioned earlier, the commercial wood pellet mill mainly consists of anti-caking silo, feeder, pelletizing chamber, Siemens motor, cutter device, safety pins and so on. Below is a detailed description of the various components of the machine for you to have a comprehensive understanding of the machine.

Anti-caking bin

Located directly above the wood pellet mill is a silo with an arch-breaking device. The design here is to consider the unique characteristics of the raw material of wood chips.

Because of the light weight and poor fluidity of the raw material, it is easy to arch in the silo. This will not only affect the running efficiency of the machine, but also affect the granulation effect. Of course, we do not want to see this, so here we are equipped with an anti-arching bin, which can continuously break the incoming wood chips to prevent arching, and ensure that the material enters the pelletizing chamber at a uniform speed and smoothly.

Stainless steel feeder

This commercial wood pellet mill has two feeders. One is a feeder equipped with a frequency conversion device, and the other is a forced feeder installed next to the pelletizing chamber.

The frequency conversion feeder is able to control and adjust the feeding speed and volume according to the production demand, ensuring that the wood pellet mill can work at maximum efficiency. And the forced feeder can push the material into the pelletizing chamber smoothly, so that the pelletizing work is completed more smoothly.

Pelletizing chamber

It is in the pelletizing chamber that the wood pellets are formed. The material is pushed into the interior of the pelletizing chamber by the force feeder, fills the inner wall of the ring die, and is eventually converted into compact wood pellets by the extrusion of the ring die and the pressure rollers, and is extruded out of the die holes.

The ring die and the pressure roller are the main working parts of the pelletizing chamber, both of which adopt high quality materials to ensure the pressing force and the quality of the formed pellets. The molds of the ring die can change according to your actual needs to get different sizes of wood pellets.

cutting device

The long length of wood pellets coming out of the mold hole needs to be cut by the cutting knife device. The customer can adjust the distance between the cutter and the ring mold to get the desired length of wood pellets.

Siemens Motor& SKF bearings

The machine adopts imported high quality Siemens motors and SKF bearings for high efficiency and long service life.

safety pins

On the outside of the pelletizing chamber, we have also equipped with safety pins. Such as the main motor is overloaded, the safety pin is broken, and it plays the role of overload protection.

Raw materials suitable for commercial wood pellet mill

Commercial wood pellet mill is suitable for a wide range of raw materials. It can process and handle almost all kinds of biomass raw materials. Including but not limited to wood chips, sawdust, tree branches, rice hulls, straw, alfalfa grass, miscanthus, bamboo, bagasse and so on. Below is a list of common raw materials that can be processed by the wood pellet machine for your reference.

  • Wood: forest logs, sawdust, furniture factory shavings, tree branches, leaves, wood chips, etc.
  • Straw: corn stalks, wheat straw, soybean straw, cotton stalks, etc.

Why make wood pellets?

Wood pellets can be used as environmentally friendly and efficient fuel pellets instead of traditional fuels such as kerosene. Besides, it has very many advantages, it is small in size and high in density, which makes it easy to be transported and stored. Here are some advantages of wood pellets, I believe that after understanding the advantages of wood pellets, you will understand why to make wood pellets.

  • Wood pellets have high combustion efficiency. The thermal efficiency of wood pellets is more than 80% higher than that of wood raw materials.1 ton of wood pellet fuel produces heat equivalent to 0.8 tons of coal.
  • Wood pellets are a kind of natural biomass pellet fuel, it does not contain sulfur and phosphorus, and does not produce polluting substances when burning, which helps to protect the environment.
  • High density of wood pellets, the density of wood pellets after molding is about 10 times of the raw material, which can save the floor space.
  • Small volume, strong mobility, easy to transport and storage, reducing the cost of transportation and storage
  • The ashes of wood pellets after burning can be recycled as high-quality fertilizer.
  • High purity, wood pellets do not contain other sundries that do not produce heat, which can save costs for the user
  • The heating capacity of wood pellets can be as high as 7000-8000 kcal/about, the thermal efficiency can be more than 90%, much higher than 60% of coal burning.
why make wood pellets

How to make wood pellets using commercial wood pellet mill

Generally speaking, the production process of making wood pellets is: crushing wood chips, drying wood chips, pelletizing wood chips, cooling wood pellets, packing wood pellets and so on. Of course, different raw materials, different production needs, the production of wood pellets production process will naturally be different. The following is a brief introduction of how to make wood pellets with 50% moisture content of logs as raw materials.

production process of making wood pellets using commercial wood pellet  mill

01 Peeling of logs

First, the logs need peeling. This makes it easier to reduce the size of the logs to meet the pelletizing requirements. At the same time, it can also ensure the pelletizing effect of wood pellets.

02 Log Chipping

After peeling, the diameter of the logs is still too big to be directly put into the crusher for crushing. Therefore, it is necessary to use a slicer to cut the logs into 3-5cm slices. It is convenient for the logs to enter into the crusher for crushing.

03 Crushing wood chips

After chipping, the wood chips can enter the crusher for crushing. The wood chip hammer mill is designed for crushing wood chips with high crushing efficiency. It is able to pulverize the wood chips to 2-3mm crumbs, which is convenient for later pelletizing.

04 Drying wood chips

Because the raw material here is logs with moisture content of 50%, which is far more than the moisture content suitable for pelletizing, i.e. about 15%. Therefore, before pelletizing, the raw material also needs drying to reduce the moisture of the raw material to about 15%.

05 Wood Chip Pelletizing

After drying, the raw material enters into the pelletizing room for pelletizing. After pressing by the pelletizing machine, the density of the wood pellets increases by about 80%, which makes the wood pellets more convenient for storage and transportation.

06 Wood pellet cooling

The humidity and temperature of the wood pellets coming from the pelletizer are very high. At this time, the wood pellets are very easy to be deformed and broken, so you can use the cooling machine to cool the wood pellets to room temperature, which can increase the hardness of the wood pellets and prolong the storage time of the wood pellets.

07 Wood pellets packing

After cooling, the wood pellets can be packed directly. Here according to the customer needs to choose manual packing or automatic machine packing and other packing methods. We provide full-automatic baling machine, which has high packing precision, fast speed and saves time and labor.
