1.8-2T/H Straw Pellet Making Machine in Vietnam

Customer Profile and Equipment Selection

The client operates a biomass pellet processing facility in Can Tho, Vietnam, focusing on producing fuel pellets for household stoves and livestock bedding pellets. The raw materials for the project include rice straw collected from local rice mills and wheat straw from nearby farms. These residues are traditionally burned or discarded, creating environmental issues and wasted resources.

The CZLH420 model biomass pellet machine was selected based on the client’s operational needs:

• Main motor power: 90 kW
• Arch-breaking feeder: 3 kW
• Forced feeder: 1.5 kW
• Ring die diameter: 420 mm
• Pellet diameter: 4–12 mm
• Production capacity: 1.8–2.0 tons per hour

The client purchased this single unit to integrate into their existing straw pellet production line. The machine focuses on processing straw efficiently, a material that is light, fibrous, and prone to bridging, making it challenging for smaller or less advanced pellet machines.

Raw Materials and Local Processing Requirements

Vietnam produces millions of tons of rice straw annually, most of which are burned in the fields after harvest. The client collects straw from cooperative arrangements with local farms and ensures a consistent supply throughout the year. The goal is to transform this low-value straw into high-density fuel pellets for domestic heating and cat litter or livestock bedding pellets, creating new revenue streams and reducing environmental impact.

Key requirements for processing straw include:

• Pellet size: 6–8 mm, optimal for fuel and bedding
• Moisture content control: Straw is pre-dried to approximately 12–15%
• High fibrous content management: Straw requires a strong conditioner to achieve uniform pellets without frequent interruptions

The CZLH420’s integrated conditioner allows continuous processing of high-fiber straw, producing pellets that meet energy density and absorption standards required for fuel and bedding products.

Operational Benefits and Integration

Integrating the CZLH420 straw pellet making machine into the facility provided the client with several advantages:

• Enhanced throughput: The machine consistently achieves 1.8–2.0 tons per hour, allowing the facility to meet growing market demand
• Consistent pellet quality: Uniform pellets enhance fuel combustion efficiency and bedding absorbency
• Durable components: High-strength steel dies and rollers reduce wear from abrasive straw materials
• Low downtime: Modular design allows for rapid replacement of worn parts
• Versatility: Capable of pelletizing rice straw, wheat straw, and mixed agricultural residues

By purchasing this single machine, the client achieved significant productivity improvement while complementing their existing pellet line without the need for a full-scale new production facility.
