2-3T/H Sunflower Husk Pellet Production Line In Russia

process design of sunflower husk pellet manufacturing plant in Russia

The sunflower husk pellet production line in Russia adopts a specially optimized biomass pellet production process, and the core process includes four key links: crushing, granulation, cooling and screening. Compared with conventional biomass pellet production lines, this process has made a number of special adjustments to the physical properties of sunflower seed shells.

1. The raw material of sunflower seed shells first enters the heavy crushing section. Due to the hard texture and special fiber structure of sunflower seed shells, ordinary crushers are difficult to effectively handle. This production line is equipped with a specially designed high-torque crusher, which crushes the raw materials to an ideal particle size of 3-5mm through a combination of specially shaped hammers and screens, creating good conditions for subsequent granulation.
2. The granulation section is the core of the entire system. The high-power MZLH420 biomass pellet machine is equipped with a high compression ratio ring die (usually 1:7 to 1:9) and heavy-duty rollers. Under high temperature and high pressure, the lignin in the sunflower seed shell softens and acts as a natural adhesive, forming the loose material into dense pellets. The process parameters are adjusted in real time according to the moisture content of the raw materials (optimal 8-12%) to ensure the molding quality.
3. The post-processing section includes efficient cooling and precise screening. The temperature of the pellets just extruded from the ring die is as high as 80-90℃, and it needs to be quickly cooled to near ambient temperature through a countercurrent cooling system, while reducing the moisture content. The vibrating grading screen is responsible for separating qualified pellets from powder to ensure that the final product meets the biomass fuel standard.

This process omits the mixing and packaging links, because as a self-use fuel, it does not require formulation and commercial packaging. The simplified design reduces the investment cost by about 20%, while reducing energy consumption and equipment maintenance requirements. The sunflower husk pellet production line in Russia adopts a modular design to facilitate future expansion or transformation.

sunflower husk pellet Equipment list

The equipment selection of this sunflower husk pellet production line in Russia fully considers the particularity of sunflower seed shells and the requirements of biomass fuel production:

1. Crushing equipment: SFSP60 series heavy-duty crusher, equipped with 55kW motor and special alloy hammer. The processing capacity is 3-4 tons/hour, which can adapt to raw materials with different moisture contents. The crushing chamber is designed with an airflow adjustment device to prevent clogging of fiber materials.
2. Pelletizing equipment: The core is MZLH420 biomass sunflower seed shell pellet granulator, equipped with 132kW main motor and heavy gearbox. The ring die has a large working area and adjustable compression ratio, which can adapt to a variety of biomass raw materials. Equipped with hydraulic protection system and automatic lubrication device to ensure high-load operation stability.
3. Cooling equipment: SKLN series countercurrent cooler, with a processing capacity of 3 tons/hour. It adopts a unique air duct design with high cooling efficiency and low energy consumption. It is equipped with temperature monitoring and automatic discharge system to prevent particles from being overcooled or condensed.
4. Screening equipment: SFJZ double-layer vibrating screen, the mesh aperture is adjustable according to product specifications (usually 4mm and 6mm combination). The fully enclosed structure reduces dust spillage, and is equipped with elastic shock-absorbing devices to reduce noise.
5. The auxiliary systems: include raw material pretreatment devices, pneumatic conveying systems, dust removal equipment, and central electric control cabinets. The entire biomass pellet project is controlled by PLC, and key parameters such as temperature, pressure, and current are monitored in real time to ensure safe operation and stable product quality.

Project Features

This sunflower seed shell pellet production line has several significant features that make it stand out from similar projects.

• First, it is specially designed for high-fiber, low-viscosity sunflower seed shells, solving the technical problem that ordinary biomass equipment is difficult to handle such raw materials. By optimizing the ring die parameters and process conditions, a molding rate of more than 90% was successfully achieved, which is at the leading level among similar projects.
• Secondly, the project embodies a distinctive circular economy feature. The production line is built directly in the oil processing plant, and the raw materials are directly connected from the shelling process through a closed conveying system, realizing the "production waste-energy" closed loop in the plant. This integrated design not only reduces the cost of raw material transportation, but also maximizes the efficiency of resource utilization.

From the perspective of economic benefits, the sunflower husk pellet production line in Russia project has a short investment recovery period. According to the current Russian natural gas price, the use of self-produced pellet fuel can save more than 40% of energy costs compared to natural gas, and the investment is expected to be recovered in 2.5-3 years. At the same time, due to the reduction of waste treatment costs and ecological tax expenditures, the actual benefits are higher.

In terms of environmental performance, the combustion efficiency of sunflower hull pellets is more than 85%, the ash content is less than 5%, and the sulfur emissions are almost zero, which fully meets Russia's strict environmental standards. The use of pellet fuel also helped the company obtain the green production certification of the local government, enhancing the corporate image and market competitiveness.

Project Prospects

Sunflower hull biomass pellets have broad development prospects in Russia and surrounding areas. From the policy environment, the Russian government is vigorously promoting the resource utilization of agricultural waste and providing tax incentives and subsidy support for related projects. New ecological regulations have also prompted more companies to seek waste solutions, creating market demand for similar projects.

The trend of technological development is also encouraging. With the advancement of biomass pellet equipment technology, the cost of processing high-fiber raw materials continues to decrease and energy efficiency continues to improve. The application of new ring mold materials and intelligent control systems enables production lines to adapt to more types of agricultural waste and expand business possibilities.

From the perspective of market capacity, Russia produces millions of tons of sunflower husks every year, and the current utilization rate is less than 20%, which has great development potential. In addition to energy use, sunflower husk pellets can also be expanded to:

• Animal husbandry bedding
• Organic fertilizer carrier
• Industrial adsorption material
• Composite filler

It is particularly noteworthy that with the growth of EU biomass energy demand, Russian agricultural processing companies can fully upgrade such projects to commercial operations, while solving waste problems and creating new sources of income. For companies with a stable source of raw materials, building similar production lines will become a strategic choice to enhance comprehensive competitiveness.

The successful implementation of this sunflower husk pellet production line in Russia project proves that the value development of agricultural processing by-products can go beyond traditional feed applications and expand to broader areas such as energy and materials. With technological progress and market maturity, similar circular economy models will be more widely used in the Russian agricultural field, creating both economic and environmental benefits for companies.
