JRZL 560 Wood Pellet Mill – High-Efficiency & Eco-Friendly Biomass Fuel Forming Equipment

The JRZL 560 vertical wood pellet mill is a new high-efficiency pelletizing equipment developed specifically for the forming needs of biomass raw materials such as wood chips and straw. Featuring a vertical ring die structure with unique design concepts of vertical feeding and centrifugal distribution via rotating rollers, this machine converts agricultural and forestry waste into high-density, high-calorific value biomass pellets. It is widely used in biomass fuel plants, wood processing plants, power plants, and various waste resource utilization projects.

1. Equipment Overview & Technical Specifications

The JRZL 560 vertical biomass pellet mill incorporates a heavy-duty hardened helical gear reducer with a reinforced main shaft, delivering strong power output and stable, reliable operation.

Key Specifications:

Core components such as rollers and dies are manufactured from high-alloy wear-resistant materials and undergo specialized heat treatment, providing excellent wear resistance and extended service life.

2. Core Advantages & Technical Features

1. Vertical Feeding, Smooth & Clog-Free

The JRZL 560 adopts a vertical feeding method where material falls directly into the pelletizing chamber by gravity. Combined with the centrifugal force generated by rotating rollers, the material is evenly distributed, fundamentally avoiding common feeding blockages found in traditional equipment.

2. Stationary Die, Rotating Rollers – High Forming Rate

This model features a stationary die and rotating rollers. Material is compressed between rollers and the die, resulting in smooth discharge, uniform pellet shape, high density, and excellent hardness — significantly outperforming traditional flat die or horizontal ring die equipment.

3. Automatic Lubrication System – 24/7 Continuous Operation

Equipped with an intelligent automatic lubrication system that continuously supplies oil to key components such as bearings. This enables extended uninterrupted production without frequent manual greasing, greatly enhancing production efficiency.

4. Double-Layer Die Design – Reduced Cost, Higher Efficiency

The double-layer die hole design allows one die to be used alternately on both sides, reducing die replacement frequency and operating costs while significantly improving output and forming efficiency.

5. Air Cooling System – Extended Die Life

Equipped with a steam vent or air cooling device that effectively lowers the temperature inside the pelletizing chamber, preventing excessive wear on dies and rollers caused by high temperatures and extending the service life of wear parts.

6. Modular Design – Easy Maintenance

The equipment features a modular design with an extended main shaft structure and quickly detachable discharge nozzle. Wear parts are easy to replace. The machine is highly automated and simple to operate, requiring only one person for daily operation management.

7. Dry-Forming Process – Energy Saving & Eco-Friendly

Adopts a self-heating dry-forming process that requires no additional steam system, significantly reducing energy consumption and equipment investment costs — aligning with green development principles.

3. Suitable Materials

The JRZL 560 is particularly suitable for processing biomass materials that are difficult to bind and form, including but not limited to:

• Wood chips, sawdust, wood shavings, branches, bark, wood planer shavings

• Corn stalks, wheat straw, rice straw, cotton stalks

• Rice husks, peanut shells, sunflower seed shells

• Palm empty fruit bunches, mushroom culture media, bamboo powder

• Organic fertilizer, bio-fertilizer

• Chemical materials such as carbon powder, ash, waste paper

4. Typical Applications

• Biomass Fuel Plants: Producing high-quality biomass pellets as coal substitutes for biomass boilers and power plants

• Wood Processing Plants: Converting sawdust, wood chips, and shavings into high-value pellet fuel

• Straw Processing Centers: Forming crop straw into pellets, addressing open-field burning pollution

• Comprehensive Agricultural & Forestry Waste Utilization Projects: Turning waste into valuable resources

5. Technical Comparison with Other Pellet Mills

Compared with flat die pellet mills, the JRZL 560 vertical ring die pellet mill features vertical feeding and a stationary die structure for smooth, direct feeding. Its superior heat dissipation capability and double-sided die usage increase production efficiency by over 20%.

Compared with horizontal ring die pellet mills, the JRZL 560 adopts a vertical structure with a ring die, providing more direct feeding without clogging issues from fluffy materials. Its gearbox is specifically designed for difficult-to-press biomass materials, offering stronger impact and fatigue resistance, more stable output, and better pellet quality.

6. Selection Recommendations

When selecting the JRZL 560 vertical biomass pellet mill, consider the following:

1. Material Properties: Ensure material moisture is controlled between 13%–20%. Too dry or too wet will affect pellet quality.

2. Grinding Fineness: The raw material should be ground to below 5mm to ensure pellet density and output.

3. Auxiliary Equipment: Can be integrated with grinders, dryers, cooling screens, and packaging machines for a complete pellet production line.

4. Power Configuration: Confirm plant power capacity matches the equipment power requirements (90–132 kW).

5. After-Sales Service: Choose suppliers with CE, ISO certification and on-site installation and commissioning capabilities.

7. Maintenance & Care

1. Regularly inspect dies and rollers for wear; replace when wear limits are exceeded.

2. Check automatic lubrication system for clear oil passages and normal oil levels.

3. Clean dust and material buildup at discharge outlets and cooling ducts after each shift.

4. Regularly inspect and replace gearbox gear oil as scheduled.

5. Pay attention to abnormal noises or temperature rise during operation; stop and troubleshoot promptly.

Conclusion

The JRZL 560 vertical biomass pellet mill has become a benchmark equipment in the biomass pellet fuel industry, offering advantages such as high efficiency, low energy consumption, easy operation, and low maintenance costs. Whether for biomass fuel production enterprises, wood processing plants, or agricultural straw processing centers, choosing the JRZL 560 helps efficiently utilize waste resources while delivering significant economic and environmental benefits.
