Video of leaf pellet mill
This video demonstrates how a leaf pellet mill quickly compresses fallen leaves into high-density fuel pellets. Simply feed the crushed leaves directly into the pellets, and the machine operates at high speed to achieve stable pelleting, making it both efficient and environmentally friendly.
Leaf pellets have a high calorific value and a wide range of uses, including boilers and fireplaces, making them an ideal biomass fuel alternative to coal. This equipment is not only suitable for leaves but can also process wood chips, rice husks, straw, and other raw materials, offering greater flexibility in application.
Our equipment has been exported to Russia, Brazil, USA, Australia, and other countries. Many customers have successfully built and profited from using local fallen leaves. The video on the right shows a trial run. If you are also considering turning fallen leaves into fuel, please contact us.

What is a leaf pellet mill?
Leaf pellet machine is one kind of biomass pellet machine, which can compresses lightweight biomass materials such as leaves into pellet fuel.
Leaf pellet machines with different capacities have different applications: smaller capacity machines are more suitable for pilot production, research, and small-scale plants; while larger capacity models perform better in continuous operation, energy consumption control, and pellet formation stability, meeting the needs of factory-level, commercial leaf pellet production.
RICHI’s leaf pellet machines employ mature and stable pelletizing technology and durable structural design, offering a wide range of models to meet different needs from pilot production and small-batch processing to commercial production. In addition to standard models, we also support customization based on output, finished product density, power configuration, etc., and can plan a complete leaf pellet production line for you, including crushing, drying, pelletizing, cooling, screening, and packaging.

What is the process of making pellets from leaves?
— Richi Machinery —
Converting loose leaves into high-density, easily stored fuel pellets requires a series of carefully designed process steps. This process is not simply “compression molding,” but involves a series of steps including raw material pretreatment, crushing, processing, pelletizing, and cooling. The core challenge of leaf pelleting lies in its loose volume and poor fiber toughness. From collection and sorting to final packaging, each step directly affects the calorific value, durability, and combustion performance of the pellets.
The following detailed analysis of the complete pelleting process from raw materials to finished product includes the core equipment required for key stages, the main components of the entire process, process parameter control, and a detailed explanation of each production process, helping you to fully understand the production process of leaf pellets.

Frequently Asked Questions
I want to know your leaf pellet mill price. My budget is limited and I’m looking for a small-capacity machine. Do you have a suitable model to recommend?
Yes! The price of a leaf pellet machine mainly depends on the machine’s capacity and configuration. For small-capacity leaf pellet makers, we recommend the following models:
| Model | Output (T/H) | Price (USD) |
|---|---|---|
| MZLH320 | 0.2–0.3 | $15,000–$18,000 |
| MZLH350 | 0.3–0.5 | $20,000–$23,000 |
| MZLH420 | 1.0–1.2 | $30,000–$35,000 |
These models are ideal for small-scale production or limited budgets. We generally suggest choosing a machine with a slightly higher capacity than your minimum requirement to ensure stable operation and avoid reduced output caused by leaf moisture or other raw material variations.
If you provide your expected daily output, leaf type, and available power, we can recommend the best model and send you a detailed quotation within one business day.
Can you tell me the working process of the leaf pellet mill?
Leaf pellet machine mainly consists of stainless steel feeder equipped with anti-caking arch bin, tempering device, pelletizing chamber, Siemens motor, base and so on.
Its working principle is that the material is put into the feeder by manual feeding or conveying equipment, and the powdered leaves are put into the feeder.
The feeder adopts the frequency conversion speed regulator feeder, which can control and adjust the feeding amount and feeding speed according to your personal demand. Then the material enters into the pelletizing chamber through the feeder for pelletizing. Inside the pelletizing chamber, the main working parts are stainless steel ring die and pressure roller.
The material is mainly converted into leaf pellets by the continuous extrusion of the ring die and pressure rollers, and extruded out from the die holes. The pelletizing chamber is equipped with a cutter to cut the leaf pellets to the desired length.
Three problems that need to be paid attention to when the leaf pellet mill produces fuel
Leaf pellet machine uses leaves, sawdust, straw and other new biomass energy sources to produce fuel pellets that can replace coal, making a significant contribution to the cause of environmental protection and energy. Leaf pellet machine needs to pay attention to the following three problems when producing fuel:
Storage of raw materials
To pay attention to the storage of raw materials, it is best to stack upright, the middle should have a certain stacking distance, to facilitate the evaporation of water within the leaves, need to be often exposed to the sun, to prevent the occurrence of mold.
Quality of leaves
Freshly harvested leaves have more moisture content, stacked up easy to mold, so they should be separated to dry, keep ventilated and dry, and then stored. Leaf pellet machine also has requirements for the moisture content of the leaves, to do a good job of moisture control, moisture content of about 17% when the success rate is higher.
Processing and pressing
Before feeding the machine should be test run to see whether the parts parts are normal, and deal with irregularities in a timely manner, and the feeding should be uniform, to ensure that the straw pellet machine is working. Because the fresh output of leaf pellets is relatively hot, so it should be dried before storage and packaging factory.
The pellet mill solves the problem of leaf surplus, so that it turns waste into treasure, its own superior technical performance, by the majority of users, deal with the above three problems, make production easier.
