0.3–0.5 T/H Rice Husk Sawdust Straw Compression Granulator in Thailand

Customer Profile and Purpose of Purchase

The Thai customer is a biomass pellet and animal feed producer. Their operations primarily focus on producing high-quality:

• Fuel pellets for local small-scale biomass boilers.
• Animal feed pellets for poultry and pigs.
• Biodegradable packaging pellets from rice husk blends.

The client’s raw materials consist of:

• Rice husks: Collected from nearby rice mills, naturally dried to around 13–15% moisture.
• Sawdust: Sourced from small furniture shops, mostly rubberwood and teak residues.
• Rice straw: Gathered from local farms, baled, shredded, and ground to approximately 3–5 mm particle size using an in-house hammer mill.

The standalone biomass pellet machine was chosen for flexibility and testing purposes, enabling the company to evaluate the best feedstock mix for both fuel and feed pellets. By purchasing a single machine, the customer could also gradually expand operations, avoiding the upfront costs of a complete production line.

The selected model for this biomass pellet project was MZLH350:

Raw Material Preparation and Handling

The Thai customer prepared the raw materials carefully to ensure optimal pellet formation:

• Rice husks: Stored under cover to maintain low moisture. Impurities were removed, and the husks were passed through a hammer mill to reduce particle size to around 3 mm.
• Sawdust: Sorted to remove coarse wood chips and contaminants. Moisture content kept below 15% for optimal pelletizing.
• Rice straw: Shredded from bales and ground to 3–5 mm using an on-site hammer mill. Moisture adjusted to 12–14% to ensure smooth pellet compression.

All materials were mixed in the following ratio: 50% rice husks, 30% sawdust, and 20% rice straw. This homogeneous blend allowed the granulator to produce dense, uniform pellets suitable for fuel and feed applications. The preparation also ensured minimal dust, reduced machine wear, and improved energy efficiency during pelletizing.

Equipment Function and Advantages

The rice husk sawdust straw compression granulator in Thailand provides several advantages for Thai biomass producers:

• High-quality pelletizing: Produces dense, uniform pellets with minimal dust.
• Energy-efficient operation: Optimized motor and feeder design reduces electricity consumption.
• Durable construction: Heavy-duty rollers and ring die resist wear from abrasive biomass materials.
• Versatility: Compatible with rice husks, sawdust, straw, bagasse, and other fibrous agricultural residues.
• Standalone operation: Can operate independently or integrate into pre-processing and drying systems.
• Labor reduction: Automates the pelletizing process, reducing manual handling and improving efficiency.

For this Thai customer, the granulator enabled precise control of pellet size and density, ensuring high-quality fuel pellets and consistent feed supplements. It also allowed experimentation with different feedstock ratios, optimizing both nutritional content for animal feed and calorific value for fuel applications.

Pellet Size and Applications

The MZLH350 granulator produces pellets with diameters of 4–10 mm, suitable for:

• Fuel pellets: For small-scale industrial boilers and domestic stoves.
• Animal feed pellets: Poultry and pigs easily digest the high-fiber pellets.
• Biodegradable packaging: Dense rice husk pellets for eco-friendly products.

The pellets’ uniformity minimizes dust generation, improving storage, handling, combustion efficiency, and feed consumption. The high-density pellet structure ensures better calorific value for fuel use and consistent nutritional intake for livestock.

Shipping and Logistics

The granulator was shipped from Qingdao Port, China, to Laem Chabang Port, Thailand, via sea freight. RICHI Machinery provided comprehensive support:

• Pre-shipment inspection and quality testing.
• Assistance with customs documentation and port clearance.
• On-site installation guidance and operator training.

The biomass pellet mill machine was installed within a week and immediately operational, producing high-quality pellets with minimal downtime. RICHI’s professional support ensured smooth commissioning, safe operation, and rapid return on investment for the customer.

Technical Features and Multi-Purpose Use

The MZLH350 Rice Husk Sawdust Straw Compression Granulator is designed for maximum versatility:

• Material compatibility: Handles rice husks, sawdust, straw, bagasse, and other agricultural residues.
• Pellet size flexibility: Adjustable 4–12 mm for fuel, feed, or industrial use.
• Standalone or line integration: Can operate independently or as part of a full production line.
• Durable and energy-efficient: Heavy-duty design with optimized motor ensures long-term performance with low electricity consumption.

This flexibility allows Thai producers to experiment with different feedstock ratios, test seasonal materials, and expand production according to the availability of rice husks, sawdust, and straw. The machine is suitable for both pilot-scale testing and small-to-medium commercial production.
