6-8T/H Chicken Manure Pellet Machine in Bulgaria

Project Background and Client Profile

The client operates in the Bulgarian organic fertilizer market and sources raw materials primarily from local poultry farms. Their previous equipment had limited capacity, creating a bottleneck in production and hindering their ability to satisfy the increasing orders from regional farmers and retail markets.

By purchasing a single chicken manure pellet machine, the client aimed to upgrade their production capabilities without overhauling the entire facility. The FZLH420 model offers a main motor power of 90 kW, a ring die diameter of 420 mm, a 3 kW arch breaker feeder, and a 1.5 kW forced feeder.

This configuration ensures smooth operation even when the input materials have higher moisture content, with a production capacity of 6–8 tons per hour. The final pellets were designed to be 6 mm in diameter, suitable for direct field application or retail packaging.

Raw Material Composition

In Bulgaria, fresh chicken manure is widely available. However, to enhance pellet quality and optimize nutrient content, the client mixes the chicken manure with agricultural residues. For this project, the raw material composition consists of approximately 70% fresh chicken manure (with a moisture content of 25–28%), 20% chopped wheat straw, and 10% sawdust collected from local wood processing facilities.

Because the moisture content of chicken manure exceeds 20%, the client uses a pre-existing drum dryer to lower the moisture level before pelletizing. This step ensures that the pellets form correctly and are structurally stable.

The combination of chicken manure with wheat straw and sawdust provides several benefits. It balances the carbon-to-nitrogen ratio, reduces nitrogen loss during pelletizing, increases the density of the pellets, and minimizes dust formation. The final product is a nutrient-rich, environmentally friendly organic fertilizer suitable for spreading directly on fields or for packaging and sale.

Machine Application and Production Process

The chicken manure pellet machine in Bulgaria plays a critical role in the client’s production line. The raw materials are first collected and transported to the drying section to reduce moisture content below 20%. Then, the mixture is fed into the FZLH420 organic fertilizer pellet machine using the arch breaker feeder, which prevents blockages and ensures consistent flow.

The forced feeder further ensures that materials are evenly distributed and compressed inside the ring die. The machine’s robust design allows it to process mixed organic materials, including poultry manure, straw, and sawdust, efficiently and continuously.

Once pelletized, the material passes through a cooling and sieving system to stabilize and remove any fines, producing uniform 6 mm pellets. These pellets are then either stored in bulk or packaged for sale. The client emphasizes that the pellets are purely intended for organic fertilization, and the uniform size and high density of the pellets improve handling, transportation, and field application.

Benefits and Equipment Advantages

• High production capacity of 6–8 tons per hour, which increases overall output.
• Compatibility with mixed raw materials, allowing the client to combine chicken manure with other agricultural residues like straw and sawdust.
• Energy-efficient operation, with a 90 kW main motor and optimized feeder system.
• Durable and low-maintenance design suitable for long-term operation in a small to medium-scale organic fertilizer facility.

Additionally, the machine is versatile. While the primary application is organic fertilizer production, it can also process other animal manures such as cow, pig, or sheep manure, combined with plant residues. This flexibility allows the client to experiment with different raw material blends and pellet sizes for various market demands.

Shipping and Installation

The fertilizer granulator machine was shipped from Qingdao Port in China and delivered to Varna Port in Bulgaria. Upon arrival, our team provided technical support, guiding the client through installation, commissioning, and operational training. This ensures that the client could start producing high-quality organic fertilizer pellets immediately, maximizing the return on investment.

Client Feedback

The client has expressed satisfaction with the performance of the FZLH420 chicken manure pellet machine. They highlighted the ease of integration into their existing production line, the consistent quality of the pellets, and the reliable operation even when processing mixed materials with varying moisture content.

According to the client, production efficiency has increased by 40% compared to their previous equipment, and the product quality meets both domestic standards and export requirements.

Conclusion

This organic fertilizer production project demonstrates how the chicken manure pellet machine in Bulgaria can transform the production of organic fertilizers.

By selecting the right model for their operation, the client successfully upgraded their production capabilities without replacing their entire facility. The machine’s ability to handle mixed organic raw materials, its high output, and low-maintenance design make it an ideal choice for organic fertilizer producers seeking efficiency, sustainability, and high-quality pellet production.

RICHI Machinery’s support throughout the shipping, installation, and training process further ensures that clients receive not only a high-quality machine but also professional guidance for long-term success. For any organic fertilizer producer in Bulgaria or nearby regions, investing in a chicken manure pellet machine from RICHI Machinery is a reliable solution to enhance productivity and meet market demand.
