0.3–0.5 T/H Wood Fiber Cat Litter Production Equipment in Colombia

The selected pelletizer does not include a conditioner and is intended for properly prepared biomass materials. In addition to cat litter, the customer wants to assess whether the same machine can produce suitable animal bedding pellets or wood fuel pellets during separate production runs. These additional applications would be introduced only after the feedstock and finished-product requirements have been evaluated.

A New Product Route for a Colombian Wood-Processing Business

The customer operates in Colombia's wood-processing sector, supplying prepared timber components and furniture-related materials. Its existing production activities generate several types of wood residues, including fine sawdust, planer shavings and small quantities of clean wood fibers. These materials are currently collected as by-products of the main manufacturing operation rather than prepared specifically for pellet production.

The business is considering a different approach to handling these residues. Instead of treating all loose wood material as a single low-value stream, it wants to identify which fractions can be converted into a consistent finished product. Wood-based cat litter is the first option under evaluation because the finished pellets can be packaged, stored and transported as a defined consumer product.

The proposed investment is deliberately limited to one pelletizing machine. The customer already has facilities for receiving and collecting timber residues, and some of its existing size-reduction and screening equipment may be suitable for the new process. Buying a pelletizer first allows the business to evaluate material behavior and finished-pellet quality before committing to a larger integrated plant.

This arrangement is not a replacement project. The MZLH350 wood based cat litter pellet machine will be added to the existing operation as a new processing stage. Its role is to compress prepared wood fibers into cylindrical pellets, while upstream equipment handles the preparation of the raw material and downstream equipment can be arranged for cooling, screening and packaging.

For a business entering a new product category, the main challenge is not simply forming pellets. It is producing a material that remains consistent from batch to batch. The customer therefore needs to establish a suitable feedstock blend, control moisture and particle size, and confirm that the finished pellets meet the intended product requirements before regular commercial production begins.

Which Wood Fibers Are Suitable for the Project?

The proposed feedstock consists of clean, untreated wood-processing residues. Pine sawdust and planer shavings are the principal materials under consideration, with a smaller proportion of fine wood fibers collected from suitable trimming and finishing operations. These materials must be separated from contaminated or unsuitable waste before they enter the pelletizing process.

Colombia has commercial forestry and timber-processing activities, but the availability of particular wood species varies by region and supplier. The project should therefore be based on the customer's actual procurement records and representative raw-material samples rather than an assumption that every type of wood residue is readily available in the same location.

The proposed starting blend is designed to combine fine particles with a controlled proportion of larger wood fragments. It is a trial formulation, not a guaranteed commercial recipe. The proportions should be adjusted according to particle distribution, moisture, feeding behavior and the quality of the finished pellets.

Raw material	Proposed proportion by dry weight	Purpose in the blend
Clean pine sawdust	55%	Provides the main fine-particle fraction for pellet formation
Clean pine planer shavings	25%	Uses a coarser residue stream after suitable size reduction
Screened fine wood fibers from suitable timber processing	20%	Broadens the usable residue stream while retaining control over particle size

The initial blend excludes painted timber, chemically treated wood, demolition waste, laminated boards, MDF, particleboard and other composite materials that may contain adhesives or chemical additives. Material collected from different production areas should not be mixed automatically. Its source and suitability must be checked before it is approved for cat litter production.

Particle size is another important consideration. The incoming wood fibers should be reduced and screened to provide a reasonably consistent feedstock. A preliminary preparation target of approximately 2–4 mm can be evaluated, depending on the material's shape and the pelletizing test results. Long shavings or oversized fragments may need additional grinding, while excessive fines should be controlled to maintain predictable feeding and minimize dust.

Moisture should be measured rather than estimated by appearance. A preliminary range of approximately 10–15% can be tested for the prepared material, but the final operating target depends on the blend, ambient conditions and the behavior of the wood fibers under compression. If the feedstock is too wet, additional drying may be required. If it is too dry, pellet formation and durability should be assessed before changing the operating conditions.

Selecting the RICHI MZLH350 Ring Die Pelletizer

The proposed machine for this project is the RICHI MZLH350 biomass pellet mill configured without a conditioner. It is intended to compress prepared wood fibers into cylindrical pellets through a ring die. The customer is purchasing one machine rather than two identical units, keeping the initial installation compact while the feedstock and product specification are evaluated.

The MZLH350 is a suitable candidate for a smaller production program in which the buyer wants to test a new market without immediately installing a high-capacity system. Its listed capacity is 0.3–0.5 T/H, although the output achieved with a particular wood-fiber blend must be confirmed through material testing and operating trials.

Equipment specification	RICHI MZLH350
Equipment type	Ring die biomass pelletizer
Purchase quantity	1 unit
Main motor power	37 kW
Anti-bridging feeder motor power	2.2 kW
Forced feeder motor power	0.75 kW
Ring die inner diameter	350 mm
Reference capacity	0.3–0.5 T/H
Available pellet diameter range	4–12 mm
Initial cat litter target	Approximately 6 mm

The 6 mm target falls within the machine's stated pellet diameter range. However, pellet diameter alone does not establish whether the finished product is suitable for cat litter. Pellet length, absorption behavior, dust generation, durability and the amount of fines released during handling must also be evaluated.

The listed capacity is a machine reference, not a guarantee that every wood-fiber blend will achieve the same output. Material density, moisture, particle distribution, die configuration and the required finished-pellet quality all influence production performance. The customer should confirm the expected operating range using representative samples before finalizing production plans.

The no-conditioner configuration also needs to be understood correctly. It removes the conditioning stage from the pelletizer arrangement, but it does not eliminate the need for raw-material preparation. Grinding, screening, moisture adjustment and consistent feeding remain important to the overall process.

How the New Pelletizer Fits into the Existing Workshop

The MZLH350 biomass wood pellet mill will perform one specific task: compressing prepared wood fibers into pellets. It will not replace the customer's existing timber-processing machinery or independently complete every stage of cat litter production.

Before installation, the customer should check whether the existing grinding and screening equipment can prepare enough suitable material for the proposed production rate. If the existing grinder produces excessive oversized particles or an inconsistent mixture of fines and shavings, additional preparation may be needed. The decision should be based on actual sample results and material flow rather than simply matching the nominal capacities of individual machines.

The feeding system is important because wood fibers can differ considerably in bulk density and flow behavior. The anti-bridging feeder helps reduce material accumulation, while the forced feeder supports controlled feeding into the pelletizing chamber. These features help manage the feedstock, but they cannot compensate for unsuitable material or poorly controlled moisture.

Downstream handling should be considered at the same time. Pellets leaving the machine need to be cooled and screened before packaging. Screening removes loose fines, while cooling helps the product reach a more stable condition for handling and storage. The customer should also provide adequate space for maintenance access, inspection of the ring die and rollers, and safe movement of packaged material.

Dust management is another practical requirement. Grinding, screening, conveying and packaging can release airborne wood particles. Suitable extraction and housekeeping arrangements should be assessed for the actual workshop layout, taking account of local occupational safety and fire-prevention requirements.

By integrating the pelletizer into an existing operation, the customer can reuse suitable facilities while identifying any gaps that need to be addressed. The objective is to establish a balanced process in which raw-material preparation, pelletizing, cooling and screening can operate together without unnecessary bottlenecks.

Producing Cat Litter That Meets Practical Requirements

Wood-based cat litter is not judged solely by whether the pellets look uniform. The finished product needs to perform consistently during storage, transport and use. Absorption, dust generation, pellet breakage and the condition of the material after exposure to liquid are all relevant quality considerations.

The first trial batches should be cooled and screened before evaluation. Testing pellets directly at the machine discharge may not provide a reliable indication of finished-product performance because the material can change during cooling and handling.

Absorption testing should use a repeatable method. A measured quantity of liquid can be applied to a known weight of pellets, with the time required for uptake, changes in pellet structure and remaining loose material recorded. Comparing different batches under the same conditions helps establish whether changes in the feedstock blend affect the product.

Dust should also be assessed after the pellets have been transferred, screened and handled. A batch that appears satisfactory immediately after pelletizing may generate fines during bag filling or transport. Screening can remove loose particles, but persistent breakage may indicate that the feedstock or operating conditions need further investigation.

The proposed pine-based blend should not be assumed to provide a particular absorption rate or odor-control performance without testing. Wood species, particle size, moisture and pellet structure can all affect the final result. A commercial product specification should therefore be established from actual test data rather than from the raw material description alone.

Packaging is part of the quality-control process as well. The customer should inspect the product after cooling, screening and a representative handling cycle, then confirm that the chosen packaging protects the pellets from moisture and excessive breakage during storage and distribution.

Claims concerning biodegradability, compostability or flushability should be made only where the product has been appropriately evaluated and the intended disposal method supports those claims. A wood-based composition does not automatically make every cat litter product suitable for flushing or every disposal system.

Beyond Cat Litter: Animal Bedding and Wood Fuel Pellets

The MZLH350 is a biomass pelletizer, so the basic compression process may also be relevant to other products made from suitable wood residues. This flexibility is useful for a business that generates more than one type of clean timber by-product. Nevertheless, each application requires its own feedstock checks and finished-product specifications.

• Wood-based cat litter: Clean, prepared wood fibers can be compressed into pellets intended for household pet use. The product must be evaluated for absorption, dust, durability and handling performance.
• Animal bedding pellets: Suitable wood residues may be processed into bedding products where cleanliness, moisture and manageable dust are important. Pellet size and the required behavior during use may differ from those of cat litter.
• Wood fuel pellets: Appropriate clean wood residues can be considered for fuel pellet production if the resulting pellets meet the relevant requirements for moisture, ash content, durability and combustion performance.

These products share a general pelletizing principle, but they should not be treated as interchangeable. A cat litter formulation is developed around its intended absorbent use, whereas a fuel pellet must meet the expectations of the intended combustion equipment and market. Animal bedding has its own requirements concerning cleanliness, moisture, dust and use conditions.

The customer can evaluate these products in separate production runs. For example, the initial program may focus on 6 mm cat litter pellets, while a later trial may examine a different pellet diameter for fuel or bedding applications. The same general machine may be suitable, but the feedstock blend, operating conditions and acceptance criteria must be reviewed for each product.

Material traceability should be maintained throughout these trials. Only approved clean wood residues should enter the cat litter stream, and any material from a different source should be assessed separately. Residues that are unsuitable for cat litter should not automatically be considered appropriate for animal bedding or fuel production.

Why the Customer Chose a Single-Machine Investment

The decision to purchase one pelletizer reflects the customer's current stage of development. The business has access to timber residues and existing preparation facilities, but the commercial requirements for wood-based cat litter still need to be established. A smaller initial installation allows the buyer to evaluate the product before investing in a complete automated production line.

The MZLH350 provides a defined pelletizing stage that can be assessed against the available feedstock. Once the customer has confirmed a stable blend and acceptable pellet quality, it can determine whether the existing preparation and packaging arrangements are sufficient or whether additional equipment is needed.

This approach also makes it easier to identify the source of production problems. If pellet formation is inconsistent, the business can review moisture, particle size, feeding behavior and the blend composition. If the pellets form well but generate excessive fines after cooling, the next step is to examine durability and handling rather than immediately assuming that a larger machine is required.

For a company entering the pet-product market from timber processing, this staged approach offers a practical way to evaluate an unfamiliar product category while retaining the option to expand later. The most important early investment is not simply the pelletizer itself, but the technical work required to establish a repeatable process.

RICHI's Technical Support for Wood Fiber Pelletizing

RICHI's equipment-selection process should begin with information about the actual feedstock. Representative samples of pine sawdust, planer shavings and fine wood fibers can help determine the preparation requirements and whether the proposed blend is suitable for trial production.

Relevant information includes raw-material source, moisture, particle-size distribution, expected daily availability and the target pellet dimensions. Details of the existing grinder, screening equipment, electrical supply and workshop layout also help establish whether the proposed MZLH350 can be integrated into the operation without unnecessary modifications.

Material testing can be used to assess feeding stability, pellet formation and the condition of the product after cooling and screening. These checks provide a more reliable basis for choosing operating conditions than relying on nominal capacity alone.

RICHI supplies pelletizing equipment for different biomass and cat litter applications. The appropriate configuration depends on the characteristics of the raw material and the required finished product. Wood fibers, straw, paper fibers, starch-based mixtures and mineral-based formulations do not necessarily behave in the same way during pelletizing, so equipment selection should be made for the specific application.

For this Colombian project, the technical priority is to establish whether the proposed blend of clean pine residues can be processed consistently at the intended scale. The MZLH350 is a candidate configuration, while sample evaluation and operating trials determine the practical processing conditions and achievable product quality.

Installation planning should include the machine foundation, lifting access, electrical connections, dust control and sufficient space for inspection and maintenance. The customer should also plan for operator training on normal operation, routine checks and wear-part inspection before commercial production begins.

Cat Litter Pelletizing Experience Across International Markets

RICHI has reported exporting cat litter pelletizing equipment to 80 countries. Its equipment range covers a variety of cat litter materials and product categories, including wood-based pellets, paper-based materials, plant fibers, starch-based formulations and selected mineral-based products.

Different raw materials require different technical considerations. Wood sawdust and shavings have distinct flow characteristics, paper fibers can behave differently during feeding and compression, and starch-based or mineral-based formulations may require their own process evaluation. A machine configuration suitable for one feedstock should not automatically be assumed to produce the same results with another.

Both single-material and mixed-material projects can be evaluated. Single-material production depends on the consistency of the incoming raw material, while a mixed-material process requires additional checks to understand how each component affects feeding, pellet formation, durability and the properties of the finished product.

The proposed Colombian blend contains 55% clean pine sawdust, 25% clean pine planer shavings and 20% screened fine wood fibers by dry weight. This is a starting formulation for evaluation, not a guarantee of commercial performance. Its suitability will depend on the actual wood species, material preparation, moisture and the results of pellet testing.

For unusual or locally sourced materials, representative samples are particularly useful. They help establish whether the material can be prepared and pelletized consistently, what adjustments may be necessary and whether the proposed machine configuration is appropriate for the intended product.

Shipping the Equipment to Colombia

The planned shipping arrangement is from Qingdao Port in China to the Port of Buenaventura in Colombia, subject to confirmation of the final shipping service, cargo arrangements and import requirements.

Before shipment, the customer should confirm the installation area, electrical supply, foundation and lifting access. The existing material preparation equipment should also be checked so that the first operating trials can begin with feedstock that meets the agreed preparation requirements.

During commissioning, the operating team should monitor feeding stability, pellet appearance and the conditions associated with each test batch. Early production runs should focus on establishing consistent operation and acceptable pellet quality rather than immediately pursuing the highest possible throughput.

Maintenance should follow the equipment documentation, including lubrication, inspection of the ring die and rollers, and replacement of wear parts when necessary. Clean feedstock, suitable dust management and consistent operating practices also contribute to reliable production.

Project Evaluation and the Next Technical Steps

No verified post-installation customer statement or production record has been supplied for this project. The following assessment reflects the proposed buyer's technical priorities rather than a direct customer quotation.

The principal question is whether the available pine sawdust, planer shavings and fine wood fibers can be prepared consistently and converted into a cat litter product that meets the intended market's requirements. The decision to purchase one MZLH350 keeps the initial equipment scope focused while the existing preparation facilities are evaluated for reuse.

The customer also needs to distinguish the machine's reference capacity from the output achievable with the actual feedstock. If production becomes unstable, the investigation should begin with material moisture, particle size, feeding conditions and blend composition. Recording these factors for each trial batch will help identify the source of variations.

Finished-product evaluation should take place after cooling, screening and handling. Absorption, dust generation, pellet durability and packaging performance all affect whether the product is suitable for commercial distribution. The customer should finalize the product specification only after these checks have produced consistent results.

Once the initial cat litter product has been evaluated, the business can decide whether to continue with the same feedstock, adjust the blend or test suitable wood residues for animal bedding and fuel pellets. Each additional product should be assessed against its own technical requirements rather than assumed to be a direct extension of the cat litter recipe.

A Practical Entry into Wood Fiber Cat Litter Production

The wood fiber cat litter production equipment in Colombia gives a timber-processing business a way to evaluate a new product line using suitable residues generated by its existing operations. The proposed RICHI MZLH350 has a 37 kW main motor, a 350 mm ring die and a listed reference capacity of 0.3–0.5 T/H. It is configured without a conditioner and is intended for appropriately prepared biomass materials.

The initial product target is a 6 mm wood-based cat litter pellet made from a proposed blend of clean pine sawdust, pine planer shavings and screened fine wood fibers. The formulation and operating conditions must be validated through material testing, and the finished pellets must be evaluated for absorption, dust, durability and handling performance.

The same general type of pelletizer may also be considered for suitable animal bedding and wood fuel pellets, provided the relevant feedstock and product requirements are met. These additional applications offer potential flexibility, but they require separate evaluation and should not be treated as guaranteed outcomes of the initial cat litter project.

For businesses with a reliable supply of clean wood residues, the next step is to identify the available material streams, confirm their preparation requirements and define the intended finished product. RICHI Machinery can use this information to discuss an appropriate pelletizer configuration and the technical checks needed before regular production begins.
