500 KG/H Dry Leaf Pellet Machine in Côte d’Ivoire

A Small Biomass Project Built Around Seasonal Leaf Collection

In Côte d’Ivoire, vegetation maintenance, roadside clearing, gardens and commercial landscaping generate plant residues that require collection and management. The country also has an established timber-processing sector, which can provide sawdust and other clean wood residues where suitable suppliers are available. These two material streams offer a potential starting point for a small biomass pellet project, provided that collection, storage and preparation are organized properly.

The proposed customer is a local biomass recovery operator working with landscaping contractors and nearby woodworking businesses. The business is not starting with a large industrial pellet plant. Its immediate objective is narrower: convert a selected portion of dry plant residues into a more uniform product that can be stored, handled and supplied in bags or bulk quantities.

Dry leaves are not a uniform raw material. Their composition changes with tree species, collection location, weather and storage conditions. Some loads may contain brittle leaves that are easy to grind, while others include long fibers, twigs, soil and small stones. Leaves collected from roadsides can also contain plastic litter or other contaminants. These materials must be removed rather than allowed to enter the pelletizing system.

The operator therefore intends to separate suitable dry leaves from unsuitable green waste before processing. Clean woody residues will be introduced as a supplementary material, not as a substitute for the leaf fraction. This approach makes the project more practical than attempting to pelletize every type of collected vegetation without sorting.

Raw Materials and the Proposed Mixing Ratio

The formulation below is a starting point for production trials. The percentages are calculated on a dry-matter basis, so they should not be confused with the proportions of materials weighed as received when their moisture contents differ.

The proposed blend gives dry leaves a substantial role while introducing a larger proportion of woody material to support a more consistent feedstock. It does not guarantee a particular pellet durability or heating value. The performance of the mixture will depend on the actual leaf species, the wood used, particle size, moisture content and operating conditions.

Only untreated, clean wood should be used. Painted timber, preservative-treated wood, laminated boards and material contaminated with adhesives should be excluded. These restrictions are important when sawdust comes from multiple suppliers, because its appearance alone may not reveal whether it is suitable for the intended application.

The first production trials should compare the proposed formulation with alternative blends. If the leaf fraction causes excessive ash, poor pellet strength or inconsistent feeding, its proportion may need to be reduced. If the material binds poorly, changes to the particle-size distribution or moisture level may be required. The final recipe should be based on test results rather than on a fixed percentage chosen in advance.

From Collected Leaves to a Pellet-Ready Material

The pellet machine cannot compensate for poor raw material preparation. Freshly collected leaves should first be inspected and screened to remove stones, soil, plastic and other unwanted material. Long branches and thick twigs should be separated from the leaf stream before the remaining woody fraction is processed.

Dry leaves may need shredding or grinding to obtain a more uniform particle size. Woody pruning residues require additional preparation: branches should be chipped before being processed through a hammer mill or another suitable grinder. For initial planning, a particle size of approximately 3 mm is a reasonable target for the prepared material, although the final specification should be confirmed through testing.

Very long fibers can make feeding inconsistent, while excessively fine grinding can increase energy consumption and dust generation. The purpose is not to make every particle as small as possible. It is to produce a reasonably uniform mixture that flows into the feeder and forms stable pellets under the selected operating conditions.

Moisture control is equally important. Leaves collected during wet weather may require more drying than material that has already dried naturally under suitable storage conditions. Sawdust and woody residues also need to be checked separately, because their moisture content may differ from that of the leaves.

If the prepared feedstock contains more than 20% moisture, the project should include a suitable drying stage before pelletizing. An initial target of approximately 10–15% moisture can be used for trials, but the best operating range must be established using the actual blend. The customer should not assume that all three raw materials will reach the same moisture level after an identical drying period.

Once the material has been dried and ground, the three components should be mixed evenly. Covered storage is recommended to reduce rewetting before production. A stable supply of prepared material helps the operator distinguish changes caused by the feedstock from changes caused by machine settings.

MZLH350 Dry Leaf Pellet Machine Specifications

One RICHI MZLH350 ring die biomass pellet machine is proposed for the initial installation. Its reference capacity of 0.3–0.5 T/H suits a small operation that wants to test a defined product before committing to a larger production system. The selection is based on the planned scale of the project, not on an assumption that all dry leaf mixtures will reach the rated capacity.

The 6 mm target falls within the machine's available pellet diameter range. The required pellet length, durability and fines content should be agreed according to the intended application and verified during production trials. If the buyer's combustion equipment requires a different diameter, the die specification should be reviewed before the final order.

The reference capacity is not a guaranteed output for every formulation. Leaf-heavy materials may behave differently from ordinary wood residues, particularly when the blend has high ash content, irregular particle size or inconsistent moisture. Actual throughput should be confirmed using representative samples.

The MZLH350 is equipped with an anti-bridging feeder and a forced feeder. These components help maintain material movement and controlled feeding into the pelletizing chamber. Their effectiveness still depends on suitable preparation: very long fibers, foreign objects and material that is too wet can interfere with stable operation.

Why the Customer Is Purchasing One Machine Instead of a Complete Line

The proposed purchase is an addition to the customer's existing material recovery operation, not a replacement for an entire production line. The operator already has access to collection, sorting and basic material preparation services. The immediate equipment gap is the pelletizing stage.

Purchasing one dry leaf pellet machine allows the business to establish whether its local feedstock can produce a consistent, marketable pellet. Before investing in a dryer, cooler, screening system, conveyors and automated packing equipment, the operator needs to confirm the behavior of the raw materials and the requirements of the intended buyers.

This staged approach also gives the customer time to develop reliable collection arrangements. Seasonal leaves cannot necessarily be supplied at the same rate throughout the year, so raw material availability and storage capacity need to be considered alongside the nominal machine output.

RICHI supplies individual biomass pellet machines as well as complete pellet production line equipment. Where the customer already owns suitable preparation machinery, the process can be designed to incorporate that equipment rather than duplicate it unnecessarily. If the project later expands, additional equipment can be selected around the confirmed material flow and production target.

Fuel Pellets and Other Potential Non-Feed Applications

The primary planned product is biomass fuel pellets. However, a pellet that forms successfully in the machine is not automatically suitable for every boiler or heating system. Leaf-rich pellets can have a different ash content and combustion behavior from conventional wood pellets. The finished product must be evaluated against the requirements of the intended fuel application.

Testing should cover moisture, ash content, mechanical durability and other relevant fuel properties. Depending on the buyer's requirements, additional checks may be needed to assess heating value, fines generation and combustion behavior. A customer should not assume that a leaf-based pellet can be used in the same way as a standard wood pellet without confirming its specifications.

Animal bedding pellets may be considered as a separate product if the operator can develop a clean, low-dust formulation suitable for the intended animals. This application requires its own assessment of moisture behavior, particle stability, dust and material safety. The fuel formulation should not automatically be marketed as animal bedding.

The MZLH350 configuration described here is intended for appropriate non-feed applications. It does not include a conditioning system for feed processing and should not be specified for manufacturing animal feed. The customer's product plan should remain focused on suitable biomass products unless a separate, technically appropriate process is designed.

Operating Considerations and Finished Pellet Quality

For this project, quality control starts with incoming material inspection. The operator should record where each load comes from, check its condition and moisture, and remove unsuitable material before grinding. These records help identify whether a change in pellet quality is associated with the raw material or the machine settings.

After pelletizing, the finished product should be checked for diameter, length, fines and durability. If pellets break easily during handling, the operator may need to adjust moisture, particle size or formulation. The production team should also watch for changes in material flow when the proportion of leaves varies between collection batches.

Cooling and screening may be needed before packing. Cooling supports safer handling and helps stabilize the product, while screening removes loose fines and broken pellets. The required arrangement depends on the intended storage period, delivery method and buyer's product specifications.

Dry leaves and ground plant residues can create airborne dust. Dust extraction, appropriate machine guarding, safe electrical installation and regular housekeeping should be considered throughout grinding, conveying and pelletizing. The installation should also allow access for routine inspection and maintenance.

Technical Support from RICHI Machinery

For a dry leaf pellet machine project, selecting a model is only one part of the engineering work. The material preparation system, the required pellet diameter and the intended product application all influence the final configuration. RICHI can review the proposed raw materials and existing equipment before confirming a suitable arrangement.

The technical review should establish whether the customer needs a chipper, hammer mill, dryer, mixer, cooler, screen or packing equipment in addition to the pellet machine. These items should be selected according to the condition of the actual material rather than included automatically in every project.

Customers can purchase a single biomass pellet machine or request a complete customized pellet production line. If suitable equipment is already available on site, it can be considered as part of the process design. Additional machinery can be introduced later when the material supply, product specifications and expected production volume justify the investment.

The proposed biomass pellet project in Côte d’Ivoire starts with a defined objective: prepare collected dry leaves and clean woody residues, test a controlled blend, and establish the operating conditions required for a consistent biomass pellet. The MZLH350 provides a practical equipment option for this initial stage, while the final output and fuel suitability must be demonstrated through testing.

Shipping the Equipment to Côte d’Ivoire

The proposed sea-freight route is from Qingdao Port in China to the Port of Abidjan in Côte d’Ivoire. Shipping schedules, cargo dimensions, freight arrangements and the final dispatch plan should be confirmed with the logistics provider before shipment.

Before installation, the customer should confirm the electrical supply, foundation, working space and maintenance access. The upstream preparation equipment must also be capable of supplying material with a consistent particle size and moisture level. These checks help avoid delays caused by site conditions that have not been addressed before delivery.

Commissioning should focus on stable feeding, pellet formation and the agreed finished-product specification. Recording the blend proportions, moisture level and operating conditions will help the operator develop repeatable settings as the composition of seasonal leaf collections changes.

Discuss a Dry Leaf Pellet Machine Project with RICHI

The proposed dry leaf pellet machine in Côte d’Ivoire project uses one MZLH350 ring die biomass pellet mill machine, with a reference capacity of 0.3–0.5 T/H and a target pellet diameter of approximately 6 mm. The initial formulation combines dry fallen leaves, clean sawdust and processed woody pruning residues for biomass fuel pellet production, subject to testing.

The main challenge is not simply pressing leaves into pellets. It is securing suitable raw materials, removing contaminants, controlling moisture and confirming that the finished product meets the requirements of its intended use. A representative material test is the most reliable way to establish realistic operating conditions.

RICHI can assist with reviewing the raw material, selecting suitable equipment and determining whether a single pellet machine or a complete production line is appropriate. Customers considering a similar project can provide information about their leaf species, available woody residues, moisture content, target pellet diameter and expected output to support a more accurate technical proposal.
