Introduction to Ring Die Biomass Pellet Machine
The workflow is as follows:
1. Raw material pretreatment (crushing, drying). Use a crusher to crush biomass raw materials (such as pine, poplar, fir, branches, bark, shavings, corn stalks, wheat straw, alfalfa, straw, rice husks, coconut shells, palm shells, betel nut shells, peanut shells, bamboo, building templates, furniture scraps, wooden pallets, urban garbage, etc.) to 8-12 mm. After crushing, use a dryer to dry the raw materials to a moisture content of 20-50%.
2. Production stage. The dried biomass powder is fed into the biomass pellet machine for granulation production.
3. Cooling stage. Through the cooler, the temperature of the generated biomass pellets is reduced from 70-80ºC to 20ºC to prevent cracking due to excessive temperature.
4. Packaging stage. Automatic packaging and sealing machines are used to weigh and package the products for easy storage, transportation and sales.


It is mainly used to convert agricultural and forestry wastes such as wood chips, straw, rice husks, bark, corn cobs, peanut shells, waste furniture, bamboo, waste logs, packaging boxes, etc. into high-density pellet fuel.
The working principle of the ring die biomass pellet machine is to gradually form cylindrical pellets under the extrusion and friction of the high-speed rotating ring die and pressure roller.

As a biomass equipment manufacture company, Henan Morethan Machinery always works on the biomass fuel solution, after our longly research, we have worked out a whole pellet production line, and we can provide our custom one-stop service of pellet plant. These design of the biomass pellet production line is simplified, can be increased or decreased according to the size of the factory building, the size and humidity of raw materials and the output. This design has adaptability and flexibility to meet the needs of biomass pellet manufacturers and individuals of different scale.

Features of biomass Pellet Machine
The characteristics of the straw fuel after forming the pellet fuel, the ratio is large, the volume is small, the combustion resistance is easy to store and transport. The volume after molding is 1/30~40 of the volume of the raw material, the proportion is 10~15 times of the raw material (density: 0.8-1.4), the calorific value can reach 3400~6000 kcal, and it is a solid fuel of highly volatile phenol.
