biomass pellet machine
Multi‑Purpose biomass Pellet Machine
Not all biomass is the same—and neither is our approach. Sawdust is dense; straw is fibrous; husks are abrasive. We’ve built our machines to handle each one. Here’s what we process, and how we make it work.

biomass pelletizer Models
We offer two main series: MZLH for wood chips, EFB and other materials. CZLH for crop and grass materials. Same reliability, different configurations. Here are four models that cover most production needs.
Biomass Combustion Pellet Machine
Built for sawdust, shavings, and offcuts. Heavy-duty gearbox, big-torque slow-speed rotor—think 8‑pole motor, not 4‑pole. In daily production, this means less wear, fewer die jams. We’ve seen 2.5 t/h on 520 model with 15% moisture birch. No steam needed; just dry, grind, pellet.
Price: 70,000-100,000 USD
| Model | MZLH320 | MZLH350 | MZLH420 | MZLH520 | MZLH678 | MZLH768 |
| Main Motor Power(kw) | 22 | 37 | 90 | 132 | 200 | 250 |
| Ring Die Inner Diameter（mm） | 320 | 350 | 420 | 520 | 673 | 762 |
| Output（T/H） | 0.2-0.3 | 0.3-0.5 | 1.0-1.2 | 1.5-2.0 | 2.5-3.0 | 3.0-4.0 |
Biomass Feed Pellet Machine
Straw, alfalfa, husk—fibrous and light. CZLH adds a forced feeder and anti‑bridging hopper to keep flow steady. For cattle feed, add a steam conditioner to soften fibre. On farms, our 520 model easily makes 3 t/h (8mm) with wheat straw at 14%—more than wood at equal power.

Core Components – Built to Last
A biomass pellet making machine lives or dies by its components. Here’s what we’ve learned matters most—and why our customers keep coming back for replacements.
Ring Die & Roller
The heart of the pellet mill. For wood, we suggest a 1:6 to 1:12 ratio—higher than that, and you risk blocking. Daily production shows that a 42CrMo alloy die dramatically outlasts standard steel. Pair it with a properly gapped roller (an A4 paper test works perfectly) to maximize output and avoid costly metal fatigue.
Force Feeder
This unit solves a common headache: bridging. Unlike standard feed, biomass (especially wood and straw) is light and fibrous. It just won’t flow on its own. Our horizontal force feeder uses a screw to cram material directly into the die. We’ve seen clients double their output just by adding this.
Anti-Bridging Feeder
Ever watched material just sit there, refusing to drop? That’s bridging. Our anti-bridging feeder sits on top of the main inlet. It features two counter-rotating shafts with paddles that actively break up clumps. We installed this on a site dealing with damp sawdust—the difference was night and day. It ensures a consistent, even flow into the mill.
Main motor
For biomass, we strongly recommend an 8-pole motor (around 750 RPM). Why? It delivers high torque at low speed—exactly what you need to push dense material through the die without stalling. In our experience, a 4-pole motor (high speed) will struggle and overheat. We typically spec a Siemens motor for reliability.

Wide Application Scenarios of Biomass Pellet Machine
Biomass pellet machine manufacturers aren’t just for pellet plants. They’re for anyone sitting on waste that could become resources. Sawmills, farms, power stations, even governments—if you have biomass, we can help. Contact us for a biomass pellet machine price.
Wood Processing Plants
Sawmills and furniture factories produce mountains of sawdust and shavings—often paying to dispose of it. A biomass wood pellet machine turns that cost into profit. Dry it, pelletize it, sell it. In Europe and North America, we’ve seen wood processors add six figures to their bottom line with a mid-sized line, turning waste disposal into an extra revenue stream.
Farms & Agricultural Operations
Corn stalks, wheat straw, rice husks—they pile up after every harvest, often burned in the field. A biomass pellet machine line gives farmers an alternative: fuel for greenhouses, animal bedding pellets, or a sellable product. We’ve installed systems on family farms across Asia and Africa that now run their own heating from their own waste—turning residues into real value.
Power Plants & Industrial Boilers
Biomass pellets are increasingly replacing coal in power generation and industrial heating worldwide. Large-scale plants need consistent, high-volume supply—and that means reliable biomass pelletizer equipment. Our 508 and 678 series machines run 24/7, processing wood chips, EFB, and agricultural residues into spec-grade fuel for utilities and heavy industry, year after year.
Municipal & Government Projects
Cities struggle with organic waste—yard trimmings, food processing residues, even RDF. Biomass pelletizing offers a clean solution: cut landfill volume, generate renewable energy, meet sustainability targets. We’ve partnered with municipal projects across Europe and Southeast Asia, processing diverse feedstocks into consistent fuel pellets for district heating and power generation.

Auxiliary Equipment – The Complete System
Behind every great biomass pelletizer is a team of supporting equipment. RICHI manufactures everything you need—from wood chipper that process logs to conveying equipment that moves material efficiently. Here’s what completes the picture.
Wood Chipper
Large logs and branches won’t fit in a hammer mill. The chipper reduces them to 20–40mm wood chips—the right size for grinding. We offer drum chippers from 75KW to 200KW, handling logs up to 600mm diameter. In the field, we’ve seen chippers turn a truckload of logging waste into usable feedstock in under an hour.
Hammer Mill
The hammer mill pulverizes chips and coarse materials to 3–5mm powder—the ideal particle size for pelletizing. For biomass, we use thicker screens (5mm) and tungsten-carbide-coated hammers to handle abrasive feedstocks. In daily production, proper grinding is the difference between smooth pelletizing and constant die blockages.
Rotary Dryer
Biomass moisture needs to be 10–15% for optimal pelletizing. The rotary dryer brings wet materials (50%+ moisture) down to spec. Three-cylinder designs are common—they’re more efficient and take up less space. On-site, we’ve seen dryers turn soggy sawdust into consistent, pellet-ready material that keeps production running smoothly.
Pellet Cooler
Pellets come out of the mill at 80–90°C—too hot to bag. The counter-flow cooler brings them to ambient temperature, preventing moisture condensation and mold growth. In our experience, skipping proper cooling is the fastest way to ruin a batch of pellets. We recommend cooling times of 6–15 minutes for most biomass pellets.
Vibrating Screener
Fines and broken pellets reduce product quality and can cause dust issues during combustion. The vibrating screener separates them from finished pellets. Fines get recycled back to the mill. In daily production, this simple step can improve your product grade and customer satisfaction significantly.
Conveying Equipment
We offer bucket elevators (vertical, up to 70m), screw conveyors (U-type for fluffy materials), and belt conveyors. The key? Minimize degradation. In our experience, the right conveyor setup reduces pellet breakage by 15–20% compared to poor handling systems.
