1.8-2T/H Maiden Grass Pellet Mill in Vietnam

Customer Profile and Project Motivation

The client operates as a livestock feed manufacturer, supplying local dairy and beef farms. Their primary motivation for purchasing a single maiden grass pellet mill was to establish a controlled, small-scale pellet production setup using abundant maiden grass harvested from nearby fields.

Prior to this purchase, the company relied on imported feed ingredients and loose grasses, which were inconsistent in quality. By investing in a standalone pellet mill, the client could produce uniform, high-density feed pellets, ensuring improved feed conversion rates and storage stability. The standalone unit approach allowed them to evaluate production efficiency and product quality before scaling operations.

Raw Materials and Processing Details

The client’s raw materials consist of maiden grass bales, harvested from nearby farms during the dry season. To prepare the grass for pelletization, they employ:

• Bale breaker to shred large grass bales
• Hammer mill to grind shredded grass into 2–4mm particle size suitable for the pellet mill
• Rotary dryer to reduce moisture content from approximately 18–22% down to 12% for optimal pellet formation

The client’s pellet specifications for maiden grass include:

• Raw material: Maiden grass (Miscanthus sinensis), dried and shredded
• Moisture content: ~12%
• Pellet diameter: 6–8mm
• Pellet application: Livestock feed and secondary use as biomass fuel

The CZLH420 model was selected for its compatibility with fibrous grass materials, providing a 90kW main motor and a production capacity of 1.8–2.0 tons per hour, matching the client’s pilot-scale operational requirements.

Machine Selection and Technical Advantages

The CZLH420 ring die maiden grass pellet mill in Vietnam is engineered for high-performance pelletizing of fibrous grasses and straw. The client chose this model for the following advantages:

• Ring die inner diameter 420mm, enabling continuous and uniform pellet formation
• Forced feeder system, ensuring consistent material flow and preventing blockages
• Adaptability to varying moisture content, maintaining pellet quality even when grass moisture fluctuates slightly
• Durable components, including high-strength bearings and gearboxes, ensuring long-term operational stability

This model’s versatility also allows the client to consider other feed ingredients or biomass residues in the future, such as rice straw, sugarcane bagasse, or other cultivated grasses.

Equipment Function and Application

The maiden grass pellet mill in Vietnam converts harvested grass into high-density pellets, which serve multiple purposes:

• Primary use: Ruminant feed, providing uniform nutrition and reducing waste during transport and storage
• Secondary use: Biomass fuel for small-scale boilers in nearby agricultural processing units
• Additional benefit: Efficient storage and reduced spoilage compared to loose grasses

By producing 6–8mm pellets, the client ensures consistency for animal consumption and combustion efficiency when used as biomass fuel. The pilot unit also allows the client to explore mixed formulations in the future, incorporating legumes or other forage crops.

Shipping and Logistics

The CZLH420 maiden grass pellet mill in Vietnam was manufactured by RICHI Machinery in Henan, China. The machine was shipped via sea freight and arrived at Hai Phong Port, Vietnam, the nearest major shipping port for northern industrial regions. RICHI provided detailed installation guides and technical support remotely, assisting with startup, adjustment, and troubleshooting during the initial operation phase.
