Straw Pellet Factory In Russia

RICHI MACHINERY

overview

This is a 6-7t/h straw pellet factory in Russia project. There are a lot of straw raw materials around the customer company.

According to market research, the customer decided to invest 390,000 US dollars to build a biomass pellet fuel project with an annual output of 45,000 tons. It mainly collects straw raw materials from the surrounding area to press straw pellets.

Straw pellet fuel uses solid waste such as corn stalks, wheat straw, rice straw, sunflower seed shells, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, bark, tea seed shells, etc. as raw materials.

After crushing, pressurizing, densifying, and molding, it becomes a modern clean fuel in the shape of small stick-shaped solid particles. It is also an emerging biomass power generation fuel that can replace traditional coal.

The straw pellet factory in Russia project has 50 employees. The working system is a two-shift system, working 20 hours a day, and the annual working time is 350 days.

Products and production scale

The main product of this straw pellet factory in Russia project is biomass energy pellets, and its product plan is shown in the table below.

No.	Product Name	Annual Output	Product Quality Standard
1	Biomass Energy Pellets	45,000 tons	Diameter 6~8mm; Length: 30~50mm. Density: 700~1400 kg/m3; Ash: 1~20%; Moisture ≤15%. The calorific value of straw-molded fuel blocks varies with the type of straw, and the calorific value is about 3200~4500Kcal/Kg. The burnout rate of biomass fuel can reach 96%, and the remaining 4% of ash can be recycled as potash fertilizer.

Russian straw pellet production process design

The biomass pellet fuel of this straw pellet factory in Russia project uses various crop straws, husks, etc. as raw materials. The production process consists of raw material crushing, granulation, cooling, etc. At the same time, each part is equipped with a strict quality monitoring system to ensure the quality of the product.

Process description of this straw pellet factory in Russia project:

1. Raw materials

The raw materials of this project come from wheat straw, husks, corn stalks, etc. in the surrounding rural areas. The purchased baled straw is transported to the factory area and temporarily stored in the raw material warehouse in the project area.

The purchased bundled straw is sent to the workshop warehouse by loaders, forklifts, etc., and manually loaded and unloaded to the conveyor. The straw conveyor adopts a closed structure. Some raw materials with higher moisture content will be dried in the drying yard before use.

2. Crushing

Wheat straw and corn stalks are crushed by crushers. They can be granulated only after crushing. The raw materials after crushing are less than 5mm.

3. Pellet forming

The biomass fuel pellet machine is a key equipment of the straw biomass pellet production line. The biomass pellet making machine can be used for different raw materials such as rice and wheat straw, sawdust, corn straw, bean straw, cotton straw and peanut shells, and the equipment runs stably.

The density of the processed pellet fuel can reach 0.7-1.4 tons/cubic meter. The crushed material is sent to the elevator receiving hopper through a conveyor, and the material is sent to the feeder on the top of the pelletizing and briquetting machine through a bucket elevator.

The feeder evenly sends the material to the pelletizer, and the surface of the pellets produced is smooth and the hardness is moderate. Friction between the material and the roller and the template in the pelletizer can generate a lot of heat, which can heat the material to about 80-110℃, soften the lignin, and sterilize it.

4. Cooling

When the pelletizing and molding material is discharged, the temperature of the biomass pellet fuel is as high as 80-90℃, the structure is relatively loose, and it is easy to break. It must be cooled by the air cooling system and cooled to room temperature before it can be bagged and stored.

The pellets are sent to the cooler for cooling via a belt conveyor. The moving chain plate drives the pellets to move. There is an air inlet at the bottom and a fan at the top. The cooling is completed after 2-3 minutes. The cooling process is completed inside the biomass pellet machine. The pellet machine is closed and does not produce dust.

5. Packaging and warehousing

This design uses a packaging conveyor for metering and belt packaging, and sends it to the finished product warehouse.

Public works

(1) Water supply

The water consumption of this straw pellet factory in Russia project is 2415m3/a. The water source of this project comes from the local municipal water supply network, which is mainly used as a water source for production, life and fire emergency, and can fully meet the requirements of this project.

(2) Drainage

The drainage system of the factory area adopts a rainwater and sewage diversion system. Rainwater is discharged into the municipal engineering rainwater network nearby. This project does not generate production wastewater.

The wastewater is mainly domestic sewage of employees and canteen wastewater. The canteen wastewater generated by the project is pre-treated in the grease trap and then discharged into the underground sewage treatment facility together with domestic sewage for treatment. The drainage volume of this project is 1932m3/a.

(3) Power supply

The electricity used in this straw pellet factory in Russia project is supplied by the local substation, which outputs 380V production power and 220V office and life electricity.
