MZLH Series Biomass Pellet Machine

Capacity

0.3-4.0 T/H

Power

22-250 kw

The MZLH series uses a proven ring die pelleting structure. We design it specifically for biomass fuel pellet production. The equipment delivers strong continuous production capacity. It adjusts pelleting configurations based on different raw material characteristics to produce fuel pellets with uniform density and stable size. It is suitable for biomass pellet projects that require stable output and long-term operation.

Feeding System

It handles the continuous conveying and even feeding of raw materials, providing reliable support for stable pelleting. It maintains a smooth feeding state for different materials, including wood-based materials, shells, food and processing residues, and waste-based raw materials.

Stainless Steel Feeder
• Made of stainless steel, it resists rust and is built for long-term use.
• It reduces raw material adhesion and ensures smoother feeding.

Forced Feeder
• Continuously feeds loose, lightweight materials into the pelleting chamber.
• It reduces material interruptions and blockages, improving production continuity.

Stainless Steel Regulator
• Adjusts the feeding speed based on different raw materials.
• It maintains even feeding and improves pellet formation.

Pelleting System

Determines whether pellets can form and how well they form. The ring die, roller, and cutting device work together to produce pellets. From material extrusion to pellet cutting, each step directly affects pellet quality and production efficiency.

Ring Die
• Determines pellet diameter and forming quality.
• Different hole sizes can produce different fuel pellet specifications.
• Made of wear-resistant material for long-term use.

Roller
• Continuously extrudes material for more stable pellet formation.
• The roller gap can be adjusted according to the raw material.
• It features low wear and runs more stably.

Cutting Device
• Controls pellet length for a neater finished product.
• The length can be adjusted as needed.
• It is easy to replace and simple to maintain.

Transmission System

The system uses a combination of high-quality core components to provide stable, continuous power output. It maintains stable operation even during long periods of continuous production.

Gearbox
• The gear transmission offers high efficiency and more stable power output.
• It meets the demands of continuous pellet production.

Coupling
• Transmits power smoothly and reduces operational shock.
• It lowers equipment vibration and protects transmission parts.

SKF Bearing
• SKF bearings are used in key positions.
• This ensures smoother operation and extends equipment life.

Siemens Motor
• Provides stable and reliable power output.
• It is suitable for long periods of continuous operation and runs more stably.

Safety System

Be equipped with multiple safety protection devices. These devices detect abnormalities in time, reduce the risk of equipment failure, and make production safer and more stable.

Safety Device
• Automatically protects the machine during overload.
• It reduces damage to key components and lowers maintenance risks.

Limit Switch
• Monitors the running status of key components in real time.
• It improves equipment safety and makes maintenance easier.

Equipment Performance

The entire machine features an optimized design centered on four key systems: feeding, pelleting, transmission, and safety.

These systems work together to ensure a steady flow of raw materials into the pelleting chamber and continuous pellet formation. This allows the machine to run stably for long periods, meeting the demands of industrial biomass fuel production.
