0.3–0.5 T/H Raw Cotton Stems Pellet Machine in Sudan

Client Profile and Purpose of the Equipment

The client operates a biomass fuel processing facility focused on agricultural residues. They opted for standalone raw cotton stems pellet machines for several reasons:

• Abundant raw materials: Sudan produces significant quantities of cotton stems, offering a consistent and low-cost feedstock.
• Environmental benefits: Pelletizing cotton stems prevents burning and reduces air pollution, promoting sustainability.
• Product objectives: Produce pellets of 5–10 mm diameter, suitable for biomass boilers, stoves, and small-scale energy applications.
• Operational flexibility: Using standalone machines allows the client to optimize pellet quality before committing to a full-scale production line.

The raw cotton stems pellet machine in Sudan is intended to process only raw cotton stems initially, while later, the client may include other agricultural residues such as sorghum stalks or groundnut shells to increase pellet variety and energy density.

Raw Material Source and Machine Selection

The primary raw material is raw cotton stems, collected post-harvest from local cotton farms. The stems are chopped into smaller pieces (~10–15 cm) before feeding into the pellet machine. Occasionally, small amounts of palm residues from Sudanese date palm cultivation are blended to improve pellet quality.

After assessing feedstock properties and production goals, the client selected the MZLH350 raw cotton stems pellet machine:

With two raw cotton stems pellet machines in Sudan, the facility achieves a total production of 0.6–1.0 T/H, ideal for the pilot phase and small local distribution.

Pellet Production Process

The production process for raw cotton stems pellets includes:

1. Preprocessing: Cotton stems are chopped and dried to optimal moisture content (~12–15%) to ensure smooth pelletization.
2. Pelletizing: The MZLH350 biomass pellet mill machines compress the stems into uniform pellets with high density and durability.
3. Cooling: Freshly formed pellets are cooled to prevent cracking and maintain structural integrity.
4. Screening and packaging: Pellets are screened to remove fines, ensuring uniform size and quality, and packaged for sale.

The final pellets serve as renewable fuel for industrial boilers and domestic heating, reducing reliance on traditional fossil fuels.

Technical Advantages of the Equipment

The raw cotton stems pellet machine in Sudan provides multiple benefits:

• Versatility: Capable of processing cotton stems, sorghum stalks, groundnut shells, palm residues, and other agricultural wastes.
• High-quality pellet production: Creates dense, uniform, and energy-efficient pellets suitable for multiple applications.
• Durability and low maintenance: Engineered for continuous operation under harsh field conditions.
• Compact design: Ideal for standalone units and small-scale operations.
• Energy-efficient: Reduces electricity consumption while maintaining optimal throughput.

The client highlighted that RICHI Machinery’s technical support, installation guidance, and operator training were critical in achieving smooth start-up and efficient operation.

Logistics and Shipping

The MZLH350 raw cotton stems pellet machines were shipped via sea freight to the Port of Port Sudan, the main maritime gateway for Sudan. RICHI Machinery ensured proper packaging, customs documentation, and quality checks to guarantee safe arrival and operational readiness.
