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

The core principle of wet hay/grass/alfalfa processing equipment is to compress moist hay into pellets through mechanical pressure. The key equipment is the ring die pellet mill, which needs to be combined with pretreatment processes such as crushing and drying.

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

(1) Continuous Design: Adapted to the "not suitable for long-term storage" characteristic of wet materials, it is equipped with conveyor belts, bucket elevators, and other conveying equipment to achieve continuous operation throughout the entire process of "cleaning - crushing - drying - pelletizing - cooling - screening," preventing the wet materials from accumulating and deteriorating in intermediate stages.

(2) Comprehensive Environmental Support: To address the exhaust gas from the drying process, which contains dust from the drying equipment, a cyclone dust collector + bag filter is required (to handle the dust generated during drying) to meet environmental emission requirements. This is a component that does not require significant configuration in a dry material granulation line.

(3) Energy Consumption and Cost: High initial investment, moderate operating energy consumption.

(4)Equipment Investment: It requires an additional drying system compared to a dry material line, resulting in higher overall equipment purchase and installation costs.

(5)Operating Energy Consumption: The drying process consumes heat (accounting for 40%-60% of total energy consumption), but the subsequent granulation process, due to the moisture content of the material, has lower extrusion resistance than dry materials, resulting in relatively lower motor energy consumption. Overall, energy consumption exhibits a "high at the beginning, flat at the end" characteristic.

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

Application Scenarios: Fuel plants are typically located near hay/grass/alfalfa producing areas (to ensure raw material supply). Production lines are large-scale, and the processed pellet fuel is sold externally in packaged or bulk form.

Reasons for Suitability: If biomass fuel plants purchase hay/grass/alfalfa, the raw material cost is high. Drying and pelletizing the hay using their own equipment can reduce raw material costs. Simultaneously, the produced pellet fuel (calorific value approximately 16-18 MJ/kg) can be supplied to industrial boilers, biomass power plants, etc.

TONY Brand 9-10.5 TPH Wet Hay/Grass/Alfalfa Line can process wet grass and various biomass materials related to agricultural waste into biomass pellets. Grass processing into biomass pellets has a wide range of uses .As fuel: grass pellet fuel can be used as boiler fuel for power plants, industrial boilers, civil heating and other fields. Its calorific value is similar to coal, but the price is lower, and the combustion process produces fewer pollutants, is a more environmentally friendly fuel. As feed: grass pellets processed by grass pellet machine can be used as feed for livestock. 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: 9-10.5 Ton/Hour

2. Raw materials: Wet Hay/Grass/Alfalfa

3. Moisture: About 30-35%

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 wet grass and related agricultural residues.

5. Finished Pellets Markets: Large power plants, domestic heating systems in rural and suburban areas, industrial heating facilities in rural - based industries, combustion heat applications in local manufacturing units, heating systems in rural schools and community centers, boiler rooms in small - scale rural enterprises, and canteens in rural educational institutions.,farms, feed mills.

Advantages of Raw Materials for Wet Hay/Alfalfa/Grass Processing Biomass Pellets Projects:

1. Wide and Easy-to-Obtain Sources: 

Alfalfa is widely cultivated in many regions and is compatible with other grasses such as corn stalks and wheat straw, ensuring a stable supply and eliminating reliance on scarce resources.

2. Flexible Cost Structure: 

Wet alfalfa can be purchased directly from the field at a lower price; while hay has a slightly higher purchase price, it reduces energy costs in the drying process, allowing for adjustments to the raw material ratio based on season and region to optimize costs.

3. Addresses Environmental Pain Points: 

Directly utilizing field grasses or agricultural waste avoids environmental pollution caused by straw burning and hay mold, turning waste into treasure.

Cost Advantages – Easy-to-Obtain Raw Materials, Controllable Overall Costs:

1. Low Raw Material Costs and Wide Range of Sources: 

Alfalfa is grown on a large scale in many regions, and hay can be purchased locally. It is also compatible with other agricultural waste such as corn stalks and wheat straw. The purchase price of raw materials is usually lower than that of other biomass raw materials such as wood and bamboo.

2. Low Storage and Transportation Costs:

Grass raw materials are loose and bulky. After being processed into pellets, the density increases to 1.1-1.3 g/cm³, reducing the volume by 5-8 times. This reduces storage space requirements and lowers long-distance transportation costs by 30%-50%, while also preventing the raw materials from becoming damp and deteriorating.

3. Low Replacement Costs: 

It can be directly integrated into existing biomass combustion equipment (such as household pellet stoves and industrial boilers) without requiring large-scale equipment modifications. The barrier to replacing traditional fuels such as coal and liquefied petroleum gas is low.
