1.0–1.2 T/H Rice Husk Pellet Mill in Nepal

Why the Customer Purchased a Single Rice Husk Pellet Machine

The decision to purchase a standalone rice husk pellet machine instead of a full rice husk biomass pellet production line was based on several practical considerations:

• Controlled Investment: As a medium-sized mill, the customer preferred to start small, limiting upfront capital outlay while testing the market.
• Flexible Usage: The standalone pellet mill could process husks directly from their milling operations, creating immediate fuel pellets without complex upstream preparation.
• Risk Minimization: Purchasing only a single unit allowed the mill to evaluate the business opportunity with minimal risk. If demand increased, additional units or a full production line could be added later.
• Internal Use and Market Testing: Some of the produced pellets are intended for their own boilers, reducing reliance on firewood or coal, while the rest are sold to local customers, including small brick kilns and bakeries.

This strategic approach ensured the mill could balance investment, operational ease, and potential profit while avoiding unnecessary scale for initial operations.

Raw Materials and Pellet Specifications

The customer in Nepal primarily uses 100% rice husk as raw material. Rice husks from Nepalese paddy are relatively dry and lightweight, making them ideal for pelletizing. Occasionally, small amounts of sawdust from local woodworking shops (less than 5%) are mixed in to improve pellet density and calorific value, but most production relies solely on rice husks.

For this biomass pellet project, the desired pellet diameter is 6 mm, which is compatible with the small boilers used by local industries and also aligns with regional export requirements to India. This size ensures good combustion efficiency, low ash production, and easy handling for storage and transport.

Equipment Selection: Model and Parameters

Considering the scale of the rice mill and available electricity supply, the customer chose the MZLH420 rice husk pellet mill for the project. The machine offers a balance between production capacity, durability, and energy consumption.

This capacity suits medium-sized rice mills in Nepal, allowing continuous production during peak milling periods. Operating the machine 8 hours per day, the customer can produce around 8–10 tons of rice husk pellets, sufficient for both internal fuel use and local sales.

Transportation and Delivery

Nepal is landlocked, and importing industrial equipment involves careful logistical planning. The rice husk pellet mill in Nepal was shipped via Port of Kolkata, India, the nearest major seaport commonly used for heavy machinery destined for Nepal. From Kolkata, the machine was transported overland using specialized trucks and ferries along the Indo-Nepal trade routes to reach the customer’s facility in Jhapa district.

RICHI Machinery coordinated the shipping, customs clearance, and inland transportation. The delivery process ensured the machine arrived safely, with no damage, and within the scheduled timeline.

Installation and Commissioning

RICHI provided remote guidance and technical support for installation, which included:

• Leveling the biomass pellet machine on a prepared concrete foundation.
• Connecting the main motor and feeders to the local power supply.
• Adjusting the ring die and rollers to achieve optimal pellet quality.
• Testing and tuning the feeding and compression speeds to produce uniform 6 mm pellets.

RICHI also trained the local staff on daily operation, preventive maintenance, and troubleshooting common issues. This allowed the rice mill to begin production immediately after delivery, without waiting for external technicians.

Application and Market Use

The rice husk pellets produced by this rice husk pellet mill in Nepal serve multiple purposes:

• Local Energy Supply: The mill uses part of the pellets in its own boilers for rice drying, reducing dependency on firewood.
• Small Industries: Brick kilns, bakeries, and community biomass projects purchase the pellets as a renewable energy source.
• Potential Export: The customer is exploring sales to northern India, where biomass energy is in high demand.

Benefits of Choosing RICHI Rice Husk Pellet Mill in Nepal

The customer highlighted several advantages of working with RICHI Machinery:

• High Durability: Rice husk is abrasive, but RICHI’s wear-resistant ring dies and rollers ensure long-term operation.
• Energy Efficiency: The MZLH420 rice husk pellet mill in Nepal consumes moderate power relative to production output, important for areas with limited electricity.
• Customizable Pellet Size: The mill can produce pellets from 4 mm to 12 mm, enabling flexibility for different applications.
• Professional Support: RICHI offers remote commissioning guidance, operator training, and spare parts supply to ensure continuous operation.
• Scalable Solution: If the business grows, additional machines or a full production line can be added seamlessly.

Technical Insights: How the Pellet Mill Works

The rice husk pellet mill in Nepal compresses loose husk into dense pellets using a ring die and roller system. The process involves:

1. Feeding: Husks are supplied via the anti-caking and forced feeders.
2. Compression: Rollers press husks through the ring die under high pressure.
3. Pellet Formation: Compressed husks exit the die as uniform cylindrical pellets.
4. Cooling (optional): Pellets can be air-cooled before storage or packaging.

This process improves the energy density of husks, reduces volume for storage, and produces a product suitable for commercial fuel use.

Future Development Plans

The rice mill in Nepal is considering:

• Adding a small-scale dryer to handle wet husks during the monsoon season.
• Installing a cooling and packaging system for better storage and improved sales presentation.
• Partnering with local cooperatives to expand pellet sales across the Terai region.

In the long term, the customer may upgrade to an MZLH520 rice husk biomass pellet mill if production demand increases, allowing for 1.5–2 T/H output.

Conclusion

This project demonstrates how a medium-sized rice mill in a landlocked country like Nepal can profitably convert agricultural waste into a high-value product. A single rice husk pellet mill in Nepal allows small businesses to minimize risk, utilize existing raw materials, and create renewable energy products for both local and regional markets.

RICHI Machinery’s combination of durable equipment, technical expertise, and comprehensive after-sales support makes it an ideal partner for enterprises looking to explore rice husk pellet production. The customer now has a steady supply of fuel pellets, reduced operational costs, and a path toward future expansion.
