About Straw pellet plant
This is a trial video of a straw pellet production line. The customer’s raw material is straw and grass, and we customized this production line according to the customer’s needs. This video shows how the straw pellets are produced. Because the customer’s raw material has a moisture content of about 15%, it does not need drying and can directly for crushing and pelletizing.
In short, the production process of straw pellet plant mainly includes: crushing straw, straw pelletizing, straw pellet cooling, straw pellet baling and so on. First of all, the straw is crushed, and then the crushed straw raw material is fed evenly into the pelletizing room to complete the pelletizing, and cut off by the cutter device. Then the straw pellets enter into the straw pellet cooling machine through the conveying equipment for cooling, and finally the cooled straw pellets are bagged by the pellet baler, and the pelletizing process is completed.
Why making straw pellets using straw pellet plant
The straw pellet plant has high efficiency, high output and low energy consumption. And the straw pellets made with the straw pellet making plant are smooth on the outside, strong on the inside and uniform in size. It is very popular in the pellet sales market. Here I will analyze why we should use straw pellet production plant to make straw pellets:
First of all, there are very many benefits of making straw pellets, straw pellets have many uses, high density, small size and easy transportation.
Here are the benefits and uses of straw pellets:
- Straw pellets as biomass pellets have high combustion efficiency, and do not pollute the environment, environmental protection and high efficiency.
- Straw pellets are also a good animal feed, which can provide animals with the required nutrients. Moreover, the straw pellets pressed by the pelletizing machine have a high degree of maturity and are easily digested and absorbed by animals.
- In addition, straw pellets can also work as animal bedding. For example, horse bedding, cat litter and so on. Because straw itself is a natural plant, harmless to animals, is an excellent raw material for bedding.
- Straw pellets have high density and small size, which is very convenient for transportation and storage, and also saves transportation cost and space.
- Straw pellets as biomass fuel pellets can replace coal, natural gas, etc., widely used in industrial heating and home heating and heating, etc., is a natural environmentally friendly and efficient energy.
Secondly, there are also many benefits of making straw pellets with pellet making line.
Benefits of straw pellet plant:
- Simple structure and easy to operate.The 1-2T/H straw pellet line only needs 1-2 operators to finish the whole production process. And we will provide staff training to train workers how to operate and use the straw pellet line.
- High efficiency and low energy consumption. The pellet production line has high output and can be customized from 1-45T/H straw pellet production line. If your production demand is higher, we can also customize the production line with higher output for you.
- Straw pellet plant can turn waste into treasure, processing straw into straw pellets can make seemingly useless straw become very valuable for local farmers to increase income.
- The straw pellet line has a wide range of raw materials and can process almost all biomass raw materials, such as wood chips, alfalfa, cotton stalks, peanut shells, tree branches, sawdust and other kinds of agricultural and forestry wastes.
This is why make straw pellets using a straw pellet mill.

Production process of straw pellet plant
After understanding the benefits of making straw pellets with the pellet plant, let’s look at how to make straw pellets together!
The production process of straw pellet plant is generally: crushing straw, drying straw, straw pelletizing, straw pellet cooling, straw pellet packing and so on. Below I take a straw with a moisture content of about 40% of the straw as raw materials, automatic straw pellet production line as an example to introduce the production process of this pellet making line.
(1) Straw crushing
First of all, because the length of straw is generally relatively long, it can not be directly put into the pelletizing machine for pelletizing. Therefore, it is necessary to use a biomass grinder to crush the straw to 2-3mm powder before pelletizing.
(2) Drying straw
The most suitable material for straw pelletizing has a moisture content of about 15%, so before pelletizing, you need to use a biomass dryer to cut the moisture of straw raw material to about 15%.
(3) Straw pelletizing
After drying, the material enters into the straw pellet mill through the conveying equipment. The material passes through the feeder and enters into the pelletizing chamber for pelletizing, and is finally converted into straw pellets under the extrusion of the ring die and pressure rollers, which are squeezed out of the ring die and cut off by the cutter device.
(4) Straw pellet cooling
The temperature of the freshly made straw pellets is around 80℃ and the moisture is around 25%, which will easily cause deterioration of the straw pellets and the surface will be easily broken if they are directly baled. Therefore, it is necessary to reduce the moisture and temperature of the straw pellets by using a cooling machine or direct drying. This procedure increases the hardness of the pellets and extends the storage time of the pellets.
(5) Straw Pellet Packing
After cooling, customers can use the baler to bag the straw pellets or directly stack them for storage according to their needs.
Straw pellets are used for many purposes, and the production process for making straw pellets for different purposes is naturally different. For example, the production of straw pellets used to feed animals, then the straw can be crushed and mixed with other food ingredients and then pelletizing, and the pelleting process should be tempered through the tempering device, so that the material is cooked, easy for animals to digest and absorb.
Of course, the production process of the pellet line will be different for different production needs and output. We can customize the most suitable pelletizing line for you according to your actual needs. Let’s understand the composition of the straw pellet plant below!

Composition of straw pellet plant
The composition of straw pellet plant generally has: straw crusher, straw dryer, straw granulator, conveying equipment, cleaning equipment, straw pellet cooler, straw pellet packing machine and other auxiliary equipment.
First of all, straw is usually grown in the field. The collected straw may have mixed with some iron pieces, stone pieces and other impurities. This may not only cause damage to the straw pelletizing equipment, but also affect the quality of straw pellets. Therefore, before pelletizing, we need to use cleaning equipment to clean the straw to remove impurities.
Straw crusher designed to reduce the size of straw. It has high crushing efficiency and low energy consumption, and is commonly used in straw pellet lines.
Rotary dryer machine is one of the important equipment for straw pellet production. In the production of straw pellets, especially straw used as biomass pellets, the moisture content of the material is a very strict standard. The material needs to be dried to about 15% and then pelletized to ensure the pelletizing effect.
Straw pellet machine is the key equipment of straw pellet plant. It is used to convert the crushed straw into straw pellets. It is characterized by small size, convenient operation, high efficiency and low energy consumption.
Conveying equipment plays the role of connecting hub in straw pellet production line, which can smoothly transport materials from one section to another. Common conveying equipments in straw pellet production line are screw conveyor, belt conveyor, bucket elevator and so on. Among them, belt conveyor and screw conveyor are mainly for horizontal transportation, while bucket elevator is used for vertical transportation.
Straw pellet cooler
Straw pellet cooler adopts counter-current cooling principle, with fast cooling speed and low energy consumption, it is the ideal equipment for cooling straw pellets.
The straw pellet packing machine is a machine used to bag the straw pellets according to the demand.
