1. The working principle of dried hay/grass/alfalfa biomass pellet processing equipment

The pellet mill is the core equipment, and its working principle is based on the extrusion of material by the pressure rollers and the die. When the material is fed into the pellet mill, the motor drives the main shaft through a gearbox or reducer, and the main shaft drives the pressure rollers to rotate. During the rotation of the pressure rollers, the material is squeezed into the holes of the die. Under the action of high temperature and high pressure, the lignin in the sawdust softens, and its cellulose molecular clusters are misaligned, deformed, and extended. Adjacent biomass pellets interlock with each other, thus automatically forming the pellets without the need for binders.

2. Characteristics of dried hay/grass/alfalfa biomass pellet processing equipment

Modern hay pellet processing equipment increasingly employs automation and intelligent control technologies to reduce manual labor intensity and improve production efficiency. The equipment is equipped with advanced control systems, allowing operators to set operating parameters, monitor equipment status, and remotely control the equipment via a user interface. For example, a PLC control system can precisely control the equipment's start-up, shutdown, and speed adjustment, while simultaneously collecting and analyzing various data during operation, such as temperature, pressure, and output, to inform production decisions.

3. Application scenarios of dried hay/grass/alfalfa biomass pellet processing equipment

(1) Boilers for Small and Medium-Sized Enterprises: Many small and medium-sized enterprises (SMEs) require boilers for their production processes. Traditional coal-fired boilers are increasingly restricted due to environmental concerns. Biomass pellet fuel, as a clean energy source, can replace coal in these enterprises' boilers.

(2) Home Heating and Hot Water Systems: With increasing environmental awareness and government support for clean energy, biomass pellet fuel is also entering the home market. It can be used in home heating and hot water systems, such as fireplaces and stoves.

(3) Agriculture and Forestry: In agriculture and forestry, biomass pellet fuel can be used for drying grains and heating greenhouses. Furthermore, biomass pellet fuel made from agricultural waste can help farmers dispose of agricultural waste such as straw, reducing environmental pollution.

(4) Industrial Production: Some industrial processes require large amounts of heat energy, such as food processing and textiles. Biomass pellet fuel can serve as a heat source for these industries, reducing dependence on traditional fossil fuels.

TONY Brand 6-7.5TPH Dried Hay/Grass/Alfalfa Line can process dried grass and various biomass materials related to agricultural waste into biomass pellets. Grass processed into biomass pellets has a wide range of uses. As fuel: Grass pellets can be used as fuel for power plant boilers, industrial boilers, and residential heating. Its calorific value is similar to coal, but it is cheaper and produces fewer pollutants during combustion, making it a more environmentally friendly fuel. As animal feed: Grass pellets processed by a grass pellet mill can be used as livestock feed. This method can make full use of grass, reduce feed costs, and also help solve the problem of grass disposal. These uses can not only effectively use agricultural waste, reduce environmental pollution, but also create economic benefits and promote sustainable agricultural development.

1. Capacity: 6-7.5 Ton/Hour

2. Raw materials: Dried Hay/Grass/Alfalfa

3. Moisture: About 10-15%

4. Application: All kinds of  biomass materials suitable for pellet production.

Suitable customers: Green energy companies, agricultural cooperatives, and small - scale rural processing units that have ready access to dried grass and related agricultural residues.

5. Finished Pellets Markets: The core applications of grass pellets revolve around two main directions: "clean energy substitution" and "feed supplementation," covering diverse scenarios such as industrial heating, agricultural breeding, and residential heating. This not only solves the pollution problem caused by grass waste but also provides low-cost energy and feed resources.

Industrial boiler retrofitting and centralized heating upgrades are driving annual demand to expand at a rate exceeding 15%, leading to a shortage of pellets in some areas.¹ Hay pellets have a calorific value of over 4000 kcal/kg, meeting the heating needs of industry, agriculture, and households. This project combines environmental benefits, policy support, and market demand, and its asset-light model (starting with an investment of up to 500,000 yuan) and short payback period (1.5–2 years) make it particularly suitable for entrepreneurs seeking long-term stable returns. The hay pellet processing project aligns with the "dual-carbon" policy, offering both environmental benefits and stable income, making it suitable for small and medium-sized investors.

Hay pellets and biomass pellets emit the same amount of carbon dioxide as they absorb when burned, making them a relatively environmentally friendly option. Furthermore, biomass pellet fuel ignites better than coal, is easier to ignite, and significantly reduces start-up time. The solid emissions from biomass pellet fuel are lower than those from coal, reducing slag costs and environmental pollution. Solid emissions from biomass pellet fuel consist entirely of ash, accounting for approximately 0.4% to 7.0% of the total weight; while coal combustion produces a mixture of ash, alkali, and residual coal, accounting for approximately 25% to 40% of the total weight. Coal causes far greater air pollution and boiler corrosion than biomass pellet fuel. Coal smoke contains large amounts of particulate carbon and toxic corrosive gases such as SO₂ and CO. The main components of biomass pellet fuel are C-H organic matter. The flue gas contains no particulate C and SO₂ gases, but mainly C-H volatile gases. Its SO₂ and CO emissions are close to zero. The smoke color during combustion is less than Ringelmann 1, which will significantly reduce air pollution and carbon dioxide emissions. Biomass pellet fuel has a reputation as a clean fuel internationally.
