The Process Of The Straw Pellet Plant

The production process of complete straw pellet plant can be divided into several parts: crushing section, drying section, pelletizing section, cooling and screening section and packing section. The details of each process are as follows:

working process of straw pellet plant

Crushing Section

Using straw shredder and straw hammer mill to crush the straw raw materials into appropriate pieces. Crushing is very important. Generally speaking, the crushed size would be 3-6mm. The needed equipment are straw shredder and straw hammer mill.

crushing section

Drying Section

In this processing, the crushed raw materials are dried to an appropriate moisture content. To make high quality straw pellet, drying is one of the most important parts you should pay attention to. The most suitable moisture content for the straw pellet production is 13-18%. If the moisture content is too high, the straw pellets should be easy to break apart. While if the moisture content is too low, it may be difficult to pelletizing.

Drying Process

Pelletizing Section

Pelletizing is an vital process in the straw pellet plant. This section is making the raw materials with appropriate size and moisture content into 6-12mm pellets. The main equipment used in this process is the straw pellet machine. The annular mold design of RICHI straw pellet production line equipment has different compression ratios. Annular molds with multiple compression ratios enable the straw pelletizer to process a variety of straw materials.

pelletizing section of straw pellet plant

Cooling And Screening Section

After pelletizing, the temperature of the pellets out of the wood pellet making machine is about 80℃. The cooling system is cooling the pellets to about room temperature through the indoor air. Also, the cooled pellets is more hard and not easy to break.

The screening process is to select the unqualified pellets to go for secondary granulation through the certain diameter screen. The rotary screener is a high-efficiency material classification and screening equipment widely used in grain, feed, flour, chemical industry, food and other industries.

Packing Section

The packing system is the last process of the whole straw pellet plant. The packing system is fully automatic design, more convenient for operation and use. It is a good equipment to improve labor efficiency, reduce labor intensity, save manpower and reduce transportation costs.

Why To Use Straw Pellet Plant?

With the development of the social economy, coal, crude oil, natural gas, and other consumer markets are expanding rapidly, the tension of energy demand is becoming more and more serious, and the price continues to soar, which has become a serious constraint on social and economic development. At the same time, this kind of energy production and consumption structure has caused a lot of pollutants such as CO₂, SO₂, soot and ash, which has exacerbated the air greenhouse effect and the unsustainable natural environment.

The vast majority of firewood, wood waste from the forest products industry, wood wastes from the paper industry, sawdust from the grain manufacturing plant and other wastes become the natural environment burden of various manufacturing industries and increase the solution cost.

Making pellets through the straw pellet plant, on the one hand, can alleviate the energy shortage. On the other hand, it can also solve the environmental pollution caused by straw and waste wood. It can be used as a fuel for civil heating and domestic energy. It is clean, pollution-free, and convenient for storage and transportation. It can also be applied for industrial boiler and kiln fuel, which can replace coal and gas to solve environmental pollution. What’s more, it can be used as fuel for gasification power generation and thermal power generation to solve the shutdown of small thermal power plants. The most important thing is that the ash from the combustion of biomass pellet fuel is a high-quality organic potassium fertilizer, which can be used for fertilization.

FAQ of straw pellet plant

question

Straw Pellet Machine – How To Make Straw Fuel Pellet?

A straw pellet machine is special mechanical equipment that makes sawdust, corn straw, peanut shell, straw, cotton and firewood straw, tree branches, edible fungus waste, cow dung and other raw materials into high-density combustible high-quality particles.

corn stalk pellet machinery

The principle of squeeze pressure friction interaction between the pressure wheel and the mold is adapted to shape the material. No additives or binders are required during processing. Straw and other materials contain a certain amount of cellulose and lignin. Lignin is not crystalline, and the main part is insoluble in any solvent at room temperature, with no melting point, but a softening point. When the temperature reaches a certain value, the lignin softening and bonding force increases, and under a certain pressure, make the cellulose molecular mass dislocation, deformation, extension, the internal adjacent biomass particles to the rodent with each other, recombination and suppression molding.

 This straw pellet machine is making the straw raw materials with the appropriate size and moisture content into 6-12mm pellets. The annular mold design of RICHI straw pellet production line equipment has different compression ratios. Annular molds with multiple compression ratios enable the straw pelletizer to process a variety of straw materials. RICHI Machinery can provide you with different straw pellet machines with various designs. If you are interested in this, just send an inquiry to us.

Straw Pellet Machine With Wide Applications

01

The straw pellet plant can be used in the production of feed pellets for ruminant animals. According to the different raw materials, it can be divided into coarse feed and concentrated feed. For example, the feed produced by the alfalfa and peanut seedling can be used in the milking cow plant. While the common feed produced with corn stalk, wheat stalk and straw is applied in the grassland pasture. By using straw feed pellets, the consumption of the grass is reduced, which inhibits the desertification of the grassland. Also, this turns straw into treasure, and the incomes of the farmers and herdsmen increase.

02

Straw pellets produced by the straw pellet plant can be used in home heating and cooking burning. In the cool region, heating is major energy consumption. For example, in winter in a rural area, if you want to make the room achieve 17℃, this requires 4 tons of coals. The development of straw pellet plant reduced the exploitation, consumption and transportation of mineral energy.

03

This can provide fuel to industrial boilers. Reducing the consumption of petroleum products and gaseous fuels can decrease the running cost of boilers. Also, it can reduce the generation of pollutants such as CO₂, SO₂, soot and ash.

04

The straw pellet produced by the straw pellet plant can be used as biological fuel in an electric generation plant. Because the biomass pellet fuel does not contain sulfur and phosphorus, the combustion does not produce sulfur dioxide and phosphorus pentoxide, so it wouldn’t lead to acid rain to pollute the atmosphere and the environment.

heating

05

A straw pellet plant can provide fuel for the rural gas supply station. The use of the gas supply station enables rural people to use the pipeline gas, which improves people’s living quality. At present, the most economic fuel of this station is biomass pellets. This is also convenient for the storage, management and anti-fire of the straw. The straw pellets can replace hard firewood such as the corncob.

In short, the straw pellet plant is a new straw processing equipment with the characteristic of low investment, huge effect, and highly practical. Using the straw pellets produced by this equipment is a new way to solve the problem of the lack of rural energy and exploit new biomass energy. This can also improve the rural environmental condition. The straw pellet plant and the products have great effects on economic and social incomes. The most important thing is that it can realize the sustainable development of energy through saving energy and reducing consumption.

question

How to start the straw pellet business?

There is no doubt that straw pellet fuel is promising. There is no doubt that biomass pellet fuel has a market prospect. If you have enough raw materials suitable for the manufacture of pellets fuel, you can consider establishing a straw pellet plant. But before you make this decision, ask yourself the following several questions.

01 What Is Your Raw Material?

There are too many raw materials that can be made into pellets, from common straw, sawdust and logs to some oil palm trunks or bamboo. Raw materials determine everything. It determines the combustion value of the final product. It determines whether you need a crusher or dryer to adjust the size and moisture content of the material. It determines what type of pellet machine you need.

raw material

02 The Initial Size Of Raw Materials

It is not easy to make pellets. It is not just necessary to feed raw materials of any shape into the straw pellet machine and wait for the pellets to come out. In fact, we encounter various materials with different shapes. They can be powder, blocks, pieces of wood, or even whole tree trunks. However, the production of particles needs to be carried out in a moderate and stable manner. This is why you can always find the crusher in the straw pellet production line. Its goal is to cut raw materials in uniform size.

03 Do You Need A Dryer Or Drying System?

When talking about pellet production, the moisture content of raw materials is a key factor that you need to carefully review. You may not know that higher moisture content will increase the final cost because you need more investment to dry the material to an acceptable moisture content (usually about 13-18%). The drying system needs high energy consumption, which means more money. In fact, in most of the pellet plants, we are building, drying systems are necessary.

dryer

04 What Size Pellets Do You Need?

In the biomass pellet industry, particle size refers to the diameter of the cross-section. 6-12mm are the most commonly used sizes. However, if the customer needs other sizes, the supplier can meet your requirements by readjusting the ring die, which is a key part of the straw pelletizer and directly determines the final particle diameter.

kind of pellets

05 How Is Your Power Supply

Different regions may have different power conditions. For example, in China, the industrial power supply is lower than 380V, 50Hz, and three-phase, while residential conditions are lower than 220V, 50Hz, and single-phase. This is not a big problem, but please contact your supplier and ensure that they are provided with the correct data so that they can perform the correct power calculation for you.

06 How Many Raw Materials Can You Provide Per Hour Or Day?

More supply of raw materials means that more pellets can be produced, which also means more investment funds. For example, if your raw material supply is 1 ton per hour, one small pellet machine is enough to complete this task. But if you have a raw material supply of 10 tons per hour, you certainly need a straw pellet mill with a larger capacity. The pelletizing machine accounts for a large part of the cost of the whole pellet plant.

07 What Is The Purpose Of Making Pellets?

You can either sell it for a profit or use it for your own projects. If you plan to sell, you need a packing machine.

RICHI Machinery is a reliable brand with more than 20 years of experience. RICHI can provide you with a straw pellet machine or complete design of a straw pellet production line.
