1T/H Maiden Grass Pellet Mill in Thailand

Customer Profile and Purchase Motivation

The client operates as a biomass energy processor, primarily producing fuel pellets for local households and industrial boilers. Their decision to purchase a single MZLH420 maiden grass pellet mill was influenced by several factors:

1. Expansion of product line: The company wanted to diversify from sawdust-based pellets to include maiden grass pellets, which have lower ash content and higher calorific value.
2. Trial production: Purchasing a standalone machine allowed them to evaluate pellet quality, production efficiency, and market response before scaling up.
3. Raw material availability: Maiden grass is abundant locally, but previously underutilized. By adding this pellet mill, they could convert this waste grass into value-added products.

The MZLH420 maiden grass pellet mill in Thailand was ideal for this purpose, with its 420mm ring die, 90kW main motor, and a production capacity of 1.0–1.2 tons per hour, perfectly matching the scale required for pilot production.

Raw Material Preparation and Specifications

The client sourced maiden grass in large bales from local farms. To ensure proper pelletization, they performed the following pre-processing steps:

• Bale breaking: Using a bale breaker to reduce large grass bales into manageable chunks
• Hammer milling: Grinding the chopped grass into particles around 3mm to ensure smooth flow into the pellet press
• Moisture adjustment: The fresh grass moisture content averaged 18–22%, so they used a rotary dryer to reduce it to 12–14% for optimal pellet formation

The pellets produced have a diameter of 6–8mm, suitable for multiple applications:

• Fuel pellets: Used in household and industrial biomass boilers
• Cat litter or animal bedding pellets: Absorbent and environmentally friendly
• Biomass feedstock for small power plants

Equipment Features and Advantages

The MZLH420 maiden grass pellet mill in Thailand is a ring die type pelletizer, specifically designed for fibrous materials like maiden grass, straw, and other agricultural residues. Key technical features include:

• High-capacity main motor (90kW) for consistent pellet output
• Forced feeding system to prevent clogging and ensure continuous operation
• Ring die inner diameter of 420mm, suitable for medium-scale production
• Durable construction, ensuring long-term service life even under continuous operation
• Versatile feedstock compatibility, allowing future expansion into other biomass residues such as rice straw or bagasse

The grass pellet machine’s flexibility and reliability made it the preferred choice for this client, as it could process high-fiber materials without frequent downtime or maintenance.

Operational Impact and Benefits

The maiden grass pellet mill in Thailand significantly enhanced the client’s operations:

• Production of high-quality pellets: Uniform shape, consistent density, and low dust generation
• Optimized resource utilization: Previously underutilized maiden grass is now converted into commercially valuable products
• Energy and cost efficiency: The machine’s high conversion rate and low power consumption reduce operational costs
• Market competitiveness: By producing pellets from maiden grass, the client could offer a differentiated product line to both biomass fuel and animal bedding markets

Logistics and Delivery

The MZLH420 was manufactured by RICHI Machinery in China and shipped via sea freight to Laem Chabang Port, Thailand’s primary deep-water port for industrial imports. RICHI Machinery provided comprehensive guidance on installation, commissioning, and operational training to ensure the client could operate the machine efficiently from day one.

Versatility and Application Scope

RICHI’s maiden grass pellet mill in Thailand is highly versatile, capable of processing:

• Woody biomass: Sawdust, wood chips, and shavings for fuel pellets
• Agricultural residues: Rice straw, corn stalks, sugarcane bagasse
• Animal feed ingredients: Various grasses and forages
• Industrial applications: Cat litter pellets, absorbents, and other specialty biomass products

The technical advantages of the MZLH420 include:

• Stable pellet formation for diverse feedstocks
• Continuous high-volume operation with minimal wear
• Energy-efficient design reducing operational costs
• Robust construction for long-term, low-maintenance usage

Customer Feedback

“The MZLH420 maiden grass pellet mill is highly efficient and reliable. The pellets are dense and uniform, and the machine handles fibrous material without any clogging issues.
