1 T/H Rice Husk Sawdust Straw Compression Granulator in Vietnam

Customer Profile and Purpose of Purchase

The Vietnamese client is a biomass pellet and animal feed producer. Their facility focuses on producing pellets for multiple purposes:

• Fuel pellets for small-scale power generators and domestic heating.
• Animal feed pellets for pigs and poultry using rice straw and local grasses.
• Eco-friendly packaging pellets for bio-composite materials.

The raw materials include:

• Rice husks: Collected from nearby rice mills, naturally dried to around 12–14% moisture.
• Sawdust: Sourced from furniture factories and small woodworking shops, mostly from rubberwood and acacia species.
• Rice straw: Collected from local farms, compressed into bales, shredded, and ground to 3–5 mm particle size using an in-house hammer mill.

The standalone machine is intended to integrate into existing pre-processing systems (bale shredders, hammer mills, and drying equipment) to achieve precise pellet formation while minimizing waste and optimizing energy usage. The flexibility of a single-unit system allowed the company to scale gradually without committing to a full line upfront.

The selected model for this project was MZLH420:

Raw Material Preparation and Handling

The Vietnamese company carefully prepared the materials to ensure optimal pellet formation:

• Rice husks: Collected and stored under cover to prevent moisture uptake. Sieved to remove large impurities, then fed directly into the hammer mill to achieve 3 mm particle size.
• Sawdust: Pre-sorted to remove coarse chips and contaminants. Dried if moisture exceeded 15%.
• Rice straw: Bales shredded and ground to 3–5 mm. Moisture content adjusted to 12–14% to allow smooth compression.

All raw materials were mixed in a ratio of approximately 50% rice husk, 30% sawdust, and 20% rice straw, producing a homogeneous feedstock for pellet formation. This ensured uniform pellet density, reduced dust, minimized machine wear, and improved energy efficiency. The preparation process also allowed the company to experiment with different material blends and moisture levels to optimize pellet quality for specific applications.

Equipment Function and Advantages

The Rice Husk Sawdust Straw Compression Granulator provides multiple advantages for Vietnamese biomass producers:

• High-Quality Pelletizing: Converts rice husks, sawdust, and straw into dense, uniform 6–10 mm pellets.
• Energy Efficiency: Optimized motor design and feeder system reduce electricity consumption while maintaining stable throughput.
• Reduced Labor Requirements: Automates pellet production and material feeding, lowering manpower needs.
• Durability: Ring die and rollers made of high-strength alloy steel resist abrasive wear, extending machine lifespan.
• Versatility: Capable of processing rice husks, wood sawdust, straw, bagasse, and other fibrous agricultural residues.
• Standalone Operation: Can work independently or integrate with existing pre-processing and drying equipment.

For the Vietnamese client, this machine allowed testing of various feedstock blends, ensuring the optimal combination for high-density fuel pellets and livestock feed. It improved feed consistency, reduced fines, minimized dust, and ensured cost-effective energy production and nutritional feed quality. The machine also allowed the operator to adjust pellet hardness, size, and moisture content based on end-use requirements.

Pellet Size and Applications

The MZLH420 biomass pellet machine produces pellets with diameters of 6–10 mm, which are ideal for:

• Fuel pellets: Used in small-scale industrial boilers and domestic stoves.
• Animal feed: Pigs, poultry, and ruminants consume the high-fiber pellets easily.
• Biocomposite material feedstock: High-density pellets for eco-friendly packaging materials.

The rice husk sawdust straw compression granulator in Vietnam ensures minimal fines and dust, improving storage stability and combustion or feeding efficiency. Its precise compression system guarantees consistent pellet density, enhancing both calorific value for fuel and nutritional uniformity for feed applications.
