2-2.5T/H Rice Husk Pellet Production Line In Sri Lanka

The customer is an entrepreneur in Sri Lanka who mainly engages in feed raw material processing and small agricultural machinery manufacturing, and has many years of storage channels for by-products such as rice husks and coconut shells.

This shift to rice husk pellets aims to utilize the large amount of rice husk waste and turn it into a combustible clean fuel through pelletization, thereby solving the ecological problem of "open-air burning of rice husks" in rural areas around the rice husk pellet production line in Sri Lanka, and exploring the industrial and household heating and carbonization applications of rice husk pellets. This is a typical biomass pellet plant case extending from agricultural waste treatment to the clean energy industry.

local rice husk resources and raw material integration strategy

Sri Lanka is an agricultural country with extensive rice cultivation, and the northern and eastern provinces have a huge amount of rice husk surplus. By signing a purchase agreement with surrounding farmers and cooperative bases, customers can obtain dozens of tons of freshly harvested rice husks every day, with a moisture content of 10-15%, high quality, small particles, and almost no impurities.

Because of its consistent raw material size, customers no longer need to crush or pre-treat, and rice husks can be used directly for pelleting, which plays an important role in simplifying the process and reducing costs in process design.

In addition, in recent years, the Sri Lankan government has encouraged the recycling of straw and rice husk resources, provided tax incentives and subsidies, and encouraged biomass pellets as clean alternative fuels. This biomass pellet project is one of the practical cases in line with this national strategy.

Streamlining the process: from the ideal goal of 5-8t/h to the practical implementation plan of 2-2.5t/h. During the rice husk pellet production line in Sri Lanka project implementation stage, the equipment configuration shifted to the "direct production" mode that takes into account simplicity and stability. The main process flow is as follows:

Feeding → Pelletizing → Cooling → Screening

According to the characteristics of rice husk raw materials, the customer cancelled the crushing and packaging sections, and focused on using a Z-type bucket elevator to feed rice husks into the husk biomass pellet machine, and matched it with a cooler and a vibrating screen to ensure the quality of the finished product. In addition, in order to adapt to the goal of circular economy, the rice husk pellet production line in Sri Lanka also reserves a connection point for subsequent carbonization treatment, which can be expanded to biomass charcoal process.

This streamlined process is suitable for projects with medium production capacity, uniform raw material size, and the desire to reduce operation and maintenance costs, which is very in line with the needs of small and medium-sized investors in the region.

Multi-material applicability of the production line: a wider business path

Although the first phase of the rice husk pellet production line in Sri Lanka project only processes rice husks, the structure of the production line shows that it has the ability to adapt to a wide range of raw materials.

Without adding crushing equipment, if customers want to process chopped coconut shell powder, shelled fruit shells, spice residues (such as cinnamon branches and leaves) and well-granulated grass powder in the future, the production line only needs to adjust the feeding system (such as adding pre-screening and preheating equipment) to be compatible, leaving multiple development directions. This provides a guarantee for the company's future capacity expansion and product diversity.

Core equipment analysis: efficient configuration and automated management

The key equipment selected for this rice husk pellet production line in Sri Lanka project is as follows:

• Z-type bucket elevator: used to safely lift bulk rice husks to the upper hopper of the pelletizer to ensure stable feeding;
• MZLH series ring die rice husk pellet machine (compatible with Φ6-8mm pellets): stable production capacity, energy-saving and efficient, suitable for the physical and chemical characteristics of rice husks themselves;
• Countercurrent cooler: quickly reduce the particle temperature to a safe storage range, with a long shelf life;
• Vibration screening equipment: remove powder and particles to ensure uniform particle size;
• Auxiliary systems such as silo systems, pipelines, and automated control cabinets.

The entire rice husk pellet production line in Sri Lanka supports one-button start and stop, fault alarm and remote monitoring, and semi-automatic operation is achieved through the PLC system, which is suitable for local skilled but non-high-skilled operators.

Market trends in Sri Lanka: Clean energy and straw burning ban policy promotion

In recent years, Sri Lanka's environmental protection pressure has increased, and many places have piloted the ban on open-air burning of rice husks to reduce PM₂.₅ emissions.

After pelletization, rice husks become a fuel with clean energy value, which is not only suitable for small and medium-sized boilers, but also can be promoted and used in farms, schools and hospital thermal energy systems. In addition, the Sri Lankan government has a stronger awareness of carbon trading policy positioning, and pelletized rice husk fuel has the potential advantage of market trading based on carbon credits.

After the first batch of rice husk pellet production line in Sri Lanka were put into production, a letter of intent was reached with several local thermal energy users. It is expected to be promoted in batches to 20+ townships in the future to form a regional community heating network.

Project summary and inspiration

This rice husk pellet production line in Sri Lanka case covers a two-year span from consultation (2022.06.24) to signing (2024.12.03), during which the strategic optimization of raw material transformation and capacity callback was experienced, which is a microcosm of the evolution from "ideal solution to executable path".

The client's identity is clear, and he is a representative of small enterprises that understand technology, can operate, and value sustainability; the process is simple and practical, and the positioning fits the characteristics of small and medium-sized and localized operations; the equipment structure is efficient, taking into account automation and low maintenance; the market prospects are bright, and it is highly consistent with Sri Lanka's biomass policy.

Through this rice husk pellet production line in Sri Lanka project, our company not only helped the local area to achieve the effective utilization of agricultural waste, but also provided a replicable model for small pellet enterprises. More importantly, the first rice husk pellet production line in Sri Lanka provides a direct demonstration for the regional circular economy, and it is expected to be further upgraded to an industrial alliance through cooperation with surrounding towns in the future.
