Complete production process of biomass pellets
How raw materials are processed into finished feed products is a fundamental requirement for most customers purchasing biomass pellet machines. The processing involves Crushing, grinding, drying, pelletizing, cooling and screening, and packaging.
Crushing
01
The small raw materials processed in the Crushing stage then undergo pulverization in a crusher, transforming them into finer powder that better suits the rolling and shaping required in the pelletizing stage.
Drying
02
Before entering the pelletizer, raw materials must have their moisture content reduced to an optimal level for pelletization. If moisture is too high, the drying stage is required.
Pelletizing
03
Pre-processed raw materials enter the pellet chamber via a forced feeder and feed chute. Inside, the material is compressed by rollers and cut by blades, ultimately forming complete biomass fuel pellets.
Cooling and Screening
04
Pellets exiting the pelletizer are typically hot, insufficiently hardened, and unsuitable for packaging. Cooling rapidly reduces their temperature to room level while enhancing hardness. A screen beneath the cooler filters out substandard pellets, ensuring product quality.
Packaging
05
Qualified pellets after cooling and screening undergo final packaging, primarily in bags. Once labeled, they are ready for distribution to sales outlets.
Frequently Asked Questions
When purchasing large machinery like biomass pellet machines, you may encounter various issues. The following questions may help address some of your concerns.
1. I want to build a 2 t/h biomass pellet plant. Can RICHI provide a comprehensive solution?
+
Yes. RICHI offers turnkey services including “raw material testing—process design—equipment selection—civil/electrical drawings—installation training.” We have customized over 200 complete lines for clients in more than 30 countries.
2. My raw material is straw with 30% moisture content. Can I feed it directly into the biomass pellet machine for processing?
+
No. The moisture content must first be dried to 12–15% before entering the pellet mill. Otherwise, it may cause die blockages and motor overload. RICHI can provide a three-drum dryer or a pipeline airflow drying system as complementary equipment.
3. For a 2 t/h output, which model should I choose? What power rating is needed?
+
We recommend the MZLH560 with a 90 kW main motor, delivering a tested wood pellet output of 1.8–2.2 t/h. For additional capacity, consider the MZLH760 with a 160 kW main motor.
4. My transformer is only 200 kVA. Is that sufficient?
+
The 560 model’s main unit consumes 90 kW, and the auxiliary equipment brings the total load to approximately 120 kW. A 200 kVA supply is barely adequate, but we recommend maintaining a 20% margin. RICHI can provide an energy efficiency calculation sheet to assist with capacity expansion design for your biomass pellet machine.
5. How should the mold compression ratio be determined? Can different raw materials share the same mold?
+
Wood chip molds require a compression ratio of 1:5–1:6, straw molds 1:4–1:4.5, and rice husk molds 1:3.5. Dedicated molds per material are optimal; mixing may cause yield loss and increased dust. RICHI offers complimentary material compression testing to determine the best ratio.
6.What is the lifespan of the molds and rollers for a biomass pellet machine, what is the cost per set, and what is the delivery lead time?
+
Alloy steel vacuum-hardened molds last 1200–1500 hours, while rollers last 800–1000 hours. The price for a 560 mold is 1800 RMB per unit, and rollers are 1200 RMB per unit. Domestic delivery lead time is 3 days, while overseas delivery takes 7–10 days.
7. What is the footprint of the entire line? What is the minimum factory height requirement?
+
The standard 2 t/h line occupies approximately 180 m² (24 m × 7.5 m). The minimum height under the crane hook must be no less than 4.5 m. RICHI can provide CAD layout drawings and dynamic load specifications.
8. Can the machine switch between 6mm and 8mm pellet diameters? What is the die change time?
+
Yes, only the ring die and press rollers need to be replaced. A single operator can complete the die change in 40–60 minutes. RICHI provides quick-release clamp structures for the biomass pellet machine, eliminating the need for pulley disassembly.
9. Is adhesive required during production?
+
Biomass feedstock naturally contains lignin, enabling self-bonding under high pressure without additional adhesives. If ash content exceeds 6%, add 1–2% food-grade starch or molasses to enhance hardness.
10. Can the biomass pellet machine operate continuously for 24 hours?
+
Yes. RICHI machinery employs Siemens motors, SKF bearings, and an oil bath lubrication system, designed for 20–22 hours of daily operation and up to 300 days of annual operation. We recommend a 30-minute shutdown per shift for blade inspection and lubrication.
