Sawdust Peanut Shells Straw Pellet Production Line in India

RICHI MACHINERY

Project Background

The client wanted a medium-capacity biomass pellet production line that could process sawdust, peanut shells, and straw with high consistency. India’s northern agricultural belt produces large quantities of these residues, yet much of it goes underutilized. The client identified a market gap for biomass pellets suitable for industrial heating and small-scale power generation.

The project aimed to:

• Convert 8,000 tons/year of raw material into standardized pellets
• Minimize environmental impact, with dust and noise control
• Utilize existing warehouse structures to reduce initial investment
• Ensure the line operates efficiently during the night to take advantage of lower electricity tariffs

Our team provided end-to-end engineering solutions: from raw material analysis, plant layout, and equipment procurement to installation supervision and environmental compliance verification.

Geographic Location and Plant Layout

Geographic Location and Plant Layout

The plant is located in northern India, close to a major regional highway. The site occupies approximately 2,000 m² and includes production halls, storage warehouses, and office facilities.

The layout was designed with the following considerations:

• Production halls placed to minimize internal material transportation
• High-noise equipment enclosed to reduce sound levels
• Centralized power and water supply to shorten pipeline lengths
• Separate storage zones for different raw materials to avoid cross-contamination

Raw Materials

The sawdust peanut shells straw pellet production line in India project leverages India’s agricultural and forestry residues. The plant receives materials from nearby farms and sawmills, ensuring a continuous supply throughout the year.

Raw Material Sources and Annual Consumption

Each raw material is first inspected and, if necessary, shredded or screened to achieve uniform particle size. A blending step ensures consistent feed to the pellet machine.

Production Line and Equipment

The sawdust peanut shells straw pellet production line in India integrates material handling, pelletizing, cooling, and dust control.

Key Equipment and Quantity

Estimated Equipment Cost: $110,000 USD

The biomass pellet mill machine produces pellets of 6–8 mm diameter and 40–50 mm length, suitable for combustion and industrial use.

Water Supply and Balance

Water is used primarily for raw material moisture adjustment.

• Production water: 1.5 m³/day
• Living water (staff, offices): 0.25 m³/day
• Water is sourced from the local municipal supply and stored in a small holding tank.

Production Process

The workflow of this sawdust peanut shells straw pellet production line in India is optimized for multi-material operation:

1. Raw material inspection and sorting – foreign objects removed to protect machinery
2. Moisture adjustment – sprinkling water as needed
3. Conveying to pellet machine – via screw conveyor
4. Pelletizing – compressing materials into uniform pellets
5. Cooling – hot pellets transferred to cooling silo
6. Packaging – packed into 50 kg bags for storage or distribution

Observations during commissioning:

• The first few tons were either too wet or too dry, which required fine-tuning of moisture content.
• Peanut shells required a slightly lower moisture compared to straw for optimal pellet quality.

Environmental Management

Dust and noise were major concerns. Measures included:

• All raw materials stored in closed warehouses, with single entry/exit for materials
• Conveyor and pelletizing zones fitted with a baghouse dust collector connected to a 15 m exhaust stack
• Mechanical exhaust fans in production halls to reduce uncollected dust
• Noise-reducing enclosures around high-decibel machines
• Green buffer zones around the site to further attenuate sound

Solid Waste Management

• Non-conforming raw materials sold or recycled
• Collected dust reused as pellet feedstock
• Staff waste collected by municipal services

Investment Summary

• Total Equipment Cost: $120,000–$140,000 USD
• Annual Raw Material Cost: Approx. $45,000 USD
• Operational Labor Cost: Approx. $12,000 USD/year
• Expected Annual Pellet Production: 8,000 tons

This cost structure makes the project financially viable for small- to medium-sized biomass pellet producers in India.

Project Prospects

India’s biomass sector is rapidly growing, supported by government incentives and the demand for renewable fuel. Pellets produced from sawdust, peanut shells, and straw are in demand for industrial boilers, power generation, and export markets. With the 3–3.5 t/h sawdust peanut shells straw pellet production line in India, the client is well-positioned to:

• Reduce agricultural waste
• Generate stable revenue from pellet sales
• Expand production capacity as market demand grows

RICHI Machinery’s experience in designing multi-material pellet lines ensures reliable operation and long-term support, making this a strong investment for Indian biomass entrepreneurs.
