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

Wet hay/grass/alfalfa (with a moisture content typically above 30%) cannot be directly pelletized. It must first undergo pretreatment to adjust its moisture content and physical properties, which is a prerequisite for ensuring pellet quality. The pretreated hay/grass/alfalfa fragments are then mechanically extruded through pelletizing equipment to transform them from "powder" to "pellets," which is the core of the entire process.

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

(1) Efficient Drying: Wet grass has a high moisture content and typically requires a drying process to reduce it to within 10-15%. Efficient drying equipment ensures that wet grass reaches the appropriate moisture content quickly, improving the subsequent pelletizing process.

(2) Durability: In wet grass pellet machines, the die and rollers are consumable parts, so the processing equipment must be durable and have a long service life. Users should pay attention to maintenance. The highly wear-resistant die and rollers used by our company have a significantly longer service life and output than standard pellet machines.

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

(1) Application scenario: A processing workshop is built in or around the wet hay/grass/alfalfa base. The harvested wet hay/grass/alfalfa is directly fed into the equipment, and after drying and pelleting, it is converted into stable pellets (feed or fuel). This avoids waste of raw materials and reduces subsequent transportation costs. 

(2) Reasons for suitability: The wet hay/grass/alfalfa harvested from large-scale planting bases usually has a high moisture content when fresh. If not processed in time, it may become moldy and heat up within 2-3 days. Moreover, the weight loss will occur during transportation due to moisture evaporation.

TONY Brand 6-7.5 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.

Wet Hay/Grass/Alfalfa is a perennial plant with high yield and excellent quality, widely cultivated and primarily used for hay, silage, or forage. Wet Hay/Grass/Alfalfa extract, after crushing, pressing, and drying, can be made into biomass pellets as an alternative to traditional fossil fuels. Wet Hay/Grass/Alfalfa biomass pellet fuel is a renewable and clean energy source that has received widespread attention and application globally in recent years. With increasing environmental protection efforts and growing demand for sustainable energy, biomass pellet fuel, with its low emissions and renewable characteristics, has become an important alternative to fossil fuels. Currently, the industry is benefiting from technological innovations such as high-efficiency compression technology and improvements in bioconversion processes, which have improved the calorific value and stability of biomass pellets. Simultaneously, policy incentives and subsidy mechanisms in many regions globally have also driven the commercialization of biomass pellet fuel.

In the future, the biomass pellet fuel industry will place greater emphasis on the diversification of raw materials and the optimization of production processes. Raw material sources will expand from traditional sawdust to a wider range of agricultural and forestry waste, and even urban organic waste, to improve raw material acquisition efficiency and reduce production costs. Furthermore, with the acceleration of the global energy transition, biomass pellet fuel is expected to be more widely used in heating, industrial boilers and small-scale power generation, becoming an important part of the green and low-carbon energy system.
