Tree Grinder Machine in Paraguay | XPJ500×500 Wood Chipper

A Project Built Around Paraguay's Eucalyptus Industry

Paraguay offers a credible setting for this type of wood-processing project. The country's National Forestry Institute, INFONA, reported that forest plantations expanded from 204,631 hectares in 2022 to 339,866 hectares in 2024. Its forestry-sector reporting also documents the growth of eucalyptus-based wood processing, including plywood, sawn timber and other products. These developments provide a real industrial context for equipment used to prepare plantation timber and its processing residues.

Wood chips are already an established biomass-related product in Paraguay. The country's environmental authority has published project records concerning the production of wood chips for biomass and the preparation of eucalyptus, pine and other wood materials for boiler fuel. This makes biomass chip production a more grounded application for the proposed machine than assigning the equipment to an unrelated or unverified market.

The proposed buyer is a regional forestry contractor serving timber plantations and local industrial customers. During harvesting, thinning and timber preparation, suitable wood may arrive in different lengths and diameters. Some pieces can be sold as logs, while others are more appropriate for chipping. The contractor wants to process the latter category instead of handling every piece as unprocessed timber.

The purchase is not intended to replace an entire sawmill or an existing biomass plant. It addresses one specific requirement: converting suitable roundwood and clean wood residues into chips with a nominal size of 20–40 mm. The commercial value of the finished product will depend on the buyer's supply agreements, material quality, operating costs and the specifications accepted by the receiving facility.

Choosing the Right Wood for Chipping

Eucalyptus is the principal raw material proposed for this project because plantation-grown eucalyptus is an established part of Paraguay's wood-processing and biomass industries. The incoming material consists mainly of small-diameter eucalyptus logs, shorter stems and suitable offcuts that are not needed for higher-value timber products. Pine can be processed in separate batches when the contractor has access to it and the end user accepts that species.

The raw material is delivered as logs, stems and irregular timber sections rather than as already-ground sawdust. This distinction determines the equipment required. A drum chipper is designed to cut suitable whole-wood pieces into chips; it is not a substitute for a hammer mill intended to reduce wood chips to fine particles.

Before feeding, the operator should separate material that contains excessive soil, stones, wire or metal. Root balls and stumps may carry dirt and embedded debris, so they should not be treated as ordinary clean logs without evaluating the risks and the required preparation. Keeping unsuitable material out of the cutting chamber helps protect the knives and reduces avoidable maintenance.

Moisture content will vary with harvesting conditions, species and storage. Fresh eucalyptus can be substantially wetter than seasoned wood stored under cover. The chipper performs size reduction, not drying. If a biomass boiler requires chips within a defined moisture range, the buyer must manage storage, seasoning or a separate drying stage according to the receiving facility's requirements.

XPJ500×500 Drum Wood Chipper Specifications

The proposed model is the XPJ500×500. Its 500 mm maximum feed diameter makes it a candidate for a contractor that handles a mixture of small and medium-sized logs and wood-processing residues. The model should not be assumed to accept every trunk encountered in forestry work; material outside its specified feed dimensions requires separate preparation or a larger machine.

The manufacturer specifies the drum chipper for processing logs, branches and wood strips into approximately 20–40 mm wood chips, with chip specifications available for customization. Actual particle distribution depends on the incoming wood, cutting arrangement, knife condition and operating settings. For this reason, the final configuration should be checked against a sample of the buyer's material and the receiving customer's requirements.

The supplied technical data does not specify a rated hourly throughput for the XPJ500×500. A production figure should not be invented from the motor power or maximum feed diameter. RICHI can review the raw-material dimensions, wood species, moisture conditions and intended working schedule before confirming the appropriate configuration and discussing a realistic production estimate.

How the New Machine Fits the Existing Yard

The proposed machine will be installed as a separate processing unit within the contractor's existing timber yard. Incoming logs are placed in a designated feeding area, where the operator checks their dimensions and removes unsuitable material. A wheel loader or other appropriate handling equipment supplies the machine according to the recommended operating procedure.

The hydraulic auxiliary feeding system helps the rollers grip and advance material into the cutting chamber. The rotating drum carries the flying knives, which cut the wood against the fixed knife arrangement. The resulting chips are discharged through the conveyor to a collection or storage area.

The yard layout should allow safe access for loading, chip discharge, inspection and knife maintenance. Electrical supply, foundation conditions, lifting arrangements and the clearance around the conveyor should be checked before installation. Since the project adds one machine to an existing operation, the design should make practical use of current equipment without compromising access or safe working distances.

Separate storage areas for incoming logs and finished chips help keep the material organized. If eucalyptus and pine are handled in different batches, the operator can identify each batch and confirm whether it meets the relevant customer's requirements. This is particularly useful when fuel specifications differ in moisture, particle dimensions or permitted contamination.

Wood Chips for Biomass Boilers and Further Processing

The principal planned output is wood chips with a nominal size of 20–40 mm. A potential market is industrial boiler operators that accept wood chips as biomass fuel. Paraguay has documented wood-chip production projects associated with biomass and boiler applications, so this end use has a clear connection to the local forestry sector.

Not every batch will automatically qualify as boiler fuel. The receiving facility may specify moisture content, particle-size distribution, bark content, ash-related contamination limits or requirements concerning the origin of the wood. The contractor should confirm these conditions before deciding how to store and dispatch the finished chips.

Wood chips can also become an intermediate raw material for wood pellet production. A typical processing route may include drying when necessary, fine grinding, pelletizing, cooling and screening. The exact equipment sequence depends on the initial moisture, chip dimensions, target pellet properties and the machinery already available at the pellet plant.

The XPJ500×500 does not perform these downstream operations. Its role is to prepare suitable wood material for the next stage. Keeping that boundary clear allows the buyer to invest in the machine it currently needs while retaining the option of adding more equipment if its business later expands into pellet manufacturing or a broader biomass processing operation.

Cutting System and Construction Features

The drum chipper uses a machine body fabricated from high-strength steel plate to support the cutting assembly during operation. The flying knives are mounted on the rotor and secured with dedicated bolts and a pressure-fastening arrangement intended to prevent movement during cutting. Correct installation and regular inspection remain essential to safe operation.

The specified flying and fixed knives use 6GrW2Si steel with quenching treatment to improve hardness and wear resistance. Knife life will still depend on operating hours, the type of wood, maintenance practices and the amount of abrasive contamination in the feedstock. Timely inspection and correct fastening are necessary to maintain cutting performance.

The rotor is checked using dynamic balancing equipment to help maintain concentricity and stable high-speed rotation. Proper balancing can reduce avoidable vibration, while overall machine stability also depends on the foundation, assembly quality and operating conditions.

The hydraulic auxiliary feeding system helps accommodate different material diameters by adjusting the feed rollers. This improves their ability to grip irregular timber and move it toward the cutting chamber. Operators must follow the manufacturer's feeding and safety procedures and keep clear of moving components while the machine is running.

Why the Buyer Is Purchasing One Machine

The buyer's priority is to add a dedicated chipping stage, not to rebuild the entire yard. Its existing handling equipment already serves the business, and the immediate requirement is limited to size reduction. A standalone drum chipper is therefore a more focused investment than purchasing a complete wood chip production line before the downstream demand has been established.

The XPJ500×500 crusher machine also provides flexibility for a business that handles different batches of suitable wood. Eucalyptus remains the main planned raw material, while pine and clean offcuts can be evaluated according to their dimensions and the requirements of individual customers. The actual production plan should be based on material availability, the machine's confirmed operating capacity and the buyer's sales arrangements.

The machine should be selected only after checking the largest expected feed diameter and the required chip specification. If the contractor regularly receives trunks larger than 500 mm, those materials cannot simply be assumed suitable for this model. A different machine or an additional preparation step may be necessary.

Technical Support Before the Order Is Confirmed

Before finalizing the order, RICHI can review photographs or representative samples of the incoming timber, including typical log diameters, lengths and the proportion of branches or offcuts. This information helps the technical team assess whether the proposed feed opening and cutting arrangement suit the intended operation.

RICHI can also review the required chip dimensions, the end use of the material, the discharge arrangement and the available installation space. If the chips will be delivered to a specific boiler or downstream processing plant, that facility's material specification should guide the final equipment configuration.

Pre-shipment coordination can cover machine dimensions, electrical requirements, installation clearances, lifting arrangements, operating documentation and recommended spare parts. These checks help the buyer prepare the site and organize installation before the machine arrives.

RICHI supplies individual wood-processing machines as well as complete biomass processing and pellet production systems to international markets. If the buyer later expands beyond chipping, the company can assess whether drying, fine grinding, conveying, pelletizing, cooling or screening equipment is appropriate. Any expansion can be planned around the existing machinery where technically suitable.

Shipping to Paraguay

Paraguay is landlocked, so ocean freight from Qingdao Port does not arrive directly at a Paraguayan seaport. For this project, the proposed overseas gateway is the Port of Montevideo in Uruguay, a regional port used on sea-freight routes serving Paraguay. The final route and transit arrangements should be confirmed with the freight forwarder before shipment.

The shipping plan should take account of the machine's packing dimensions, gross weight, loading requirements and the receiving site's unloading arrangements. Confirming these details in advance helps the buyer prepare the required lifting equipment and avoid unnecessary delays during delivery and installation.

Project Feedback and Acceptance Priorities

For this representative project scenario, the buyer's evaluation focuses on whether the machine accepts the intended eucalyptus logs, produces chips within the agreed size range and integrates with the existing yard. These are more useful acceptance criteria than a general claim that a machine is suitable for every type of wood.

After commissioning, the operator should record the wood species, feed dimensions, operating hours, chip-size distribution and maintenance observations. These records can support future operating decisions and provide the basis for a genuine customer testimonial. No unverified quotation or measured production result is attributed to a named buyer in this illustrative scenario.

Discuss a Tree Chipping Project with RICHI

The right tree grinder machine is one that matches the incoming timber, the required chip dimensions and the downstream application. For a forestry contractor in Paraguay, the proposed XPJ500×500 offers a 500 mm maximum feed diameter, a 110 kW main motor and a nominal target chip size of 20–40 mm, subject to configuration and material testing.

For Tree Grinder Machine in Paraguay, RICHI Machinery can review the raw materials, installation conditions and intended use before confirming the final equipment configuration. Whether the requirement is one drum chipper or a future complete biomass processing system, the process should be designed around the actual material and the buyer's production objectives.
