10T/H Chicken Manure Pelletizer in USA

Customer demand analysis

At the beginning of the chicken manure pelletizer in USA project, the customer elaborated on their difficulties and needs in detail.

• First, equipment reliability is the most critical consideration. The new pellet mill must be able to work stably under the 24/7 continuous operation of the US farm and ensure at least 30 days of trouble-free operation. They particularly emphasized the need to solve the bearing overheating problem of the original equipment. The temperature of the original equipment would exceed 90°C after only 4 hours of operation, seriously affecting the service life.
• In terms of production capacity, the new equipment must stably reach the designed production capacity of 10 tons/hour and be able to adapt to the fluctuation of raw material moisture content (28%-35%). The existing equipment will drop 40% when the raw material moisture content exceeds 32%, which is particularly serious in the wet season.
• In terms of product quality, the finished pellets need to meet the standards of 6 mm in diameter, 10-15 mm in length, ≥10 Newtons in crushing strength, and ≥60% in organic matter content (in line with USDA organic certification requirements).
• The pellets produced by the original equipment have large differences in length (5-25 mm), which seriously affects the subsequent packaging efficiency and market acceptance.
• Environmental compliance is also an important consideration. Dust emissions during equipment operation must be controlled below 20mg/m³, in compliance with the standards of the Occupational Safety and Health Administration (OSHA) of the United States.
• In addition, the customer also hopes that the chicken manure pelletizer in USA can be integrated with their enterprise resource planning (ERP) system to achieve real-time monitoring and analysis of production data, which is in line with the increasingly popular trend of precision agriculture in the US agricultural field.

Raw material characteristics and product positioning

The raw materials processed by this chicken manure organic fertilizer production project mainly come from chicken manure collected from modern cage chicken houses, which have unique physical and chemical properties.

1. Fresh chicken manure is first separated into solids and liquids by a screw press, reducing the moisture content from the original 70% to about 32%.
2. The material then enters a closed fermentation system and is treated for 72 hours at a precisely controlled 55°C environment. This process not only effectively kills pathogenic microorganisms, but also significantly reduces the content of odor substances.
3. The fermented material enters the existing pretreatment system. The hammer mill crushes the agglomerated manure to a particle size of 2-3 mm, and then the moisture content is further reduced to 12-14% through a chicken manure dryer.
4. During this process, customers will add about 8% rice husk powder and 3% bentonite. The former is used to adjust the carbon-nitrogen ratio and improve the particle structure, while the latter is used as a natural binder to increase the molding rate.
5. In order to meet different market needs, customers will also add specific microbial agents to some products, which need to ensure survival in subsequent processes.

Customers mainly produce two types of end products.

One type is ordinary-grade organic fertilizer granules, which are mainly for large farm customers and are packaged in 1-ton super bags. The total nutrients of nitrogen, phosphorus and potassium (N+P2O5+K2O) are required to be no less than 5%.

The other type is high-end horticultural granular fertilizer. For the home gardening market, in addition to stricter appearance requirements, chelated trace elements need to be added. This type of product is packaged in 20-pound bags with moisture-proof inner films, and the price is 2.5 times that of ordinary products.

Technical features of chicken manure pelletizer in USA

After comprehensive market research and technical evaluation, customers finally chose RICHI's FZLH520 chicken manure fertilizer pelletizer. This chicken manure pelletizer in USA exhibits excellent technical characteristics in many aspects and perfectly meets the production needs of large-scale farms in the United States.

• The ring die of the chicken manure fertilizer granulator machine is made of special alloy steel. After special carburizing quenching and cryogenic treatment processes, the surface hardness reaches HRC65, and the wear resistance is more than 4 times that of ordinary molds. The unique die hole design adopts a multi-stage variable diameter structure.
• The larger diameter at the inlet end is convenient for high-fiber materials to enter, the middle section is preliminarily compressed, and the outlet section is finally formed. This design significantly improves the processing capacity of difficult-to-form raw materials such as chicken manure. The thickness of the die plate is carefully calculated to ensure that the pellets achieve the best density and strength.
• In terms of the transmission system, our chicken manure pelletizer is equipped with heavy-duty bearings and reinforced spindles. All lubrication points use a centralized automatic lubrication system to ensure reliability under continuous high-intensity operation.
• In response to the strict environmental protection requirements of the United States, the equipment adopts a fully enclosed design, combined with an efficient pulse dust removal system, so that the dust concentration in the working area is controlled below 15mg/m³, which fully meets the OSHA standards.
• In terms of noise control, by optimizing the gear design and adding a soundproof cover, the equipment operation noise is controlled below 75 decibels, creating a better working environment.
• The chicken manure pelletizer in USA is also equipped with an energy monitoring module, which can record and analyze energy consumption data in real time to help customers optimize production costs.

The successful implementation of this chicken manure fertilizer production line in USA project was promoted by the United States Poultry Association (USPOULTRY) as a successful model. Their innovative "breeding-fertilizer-planting" circular economy model was commended by the Arkansas Department of Agriculture and received corresponding tax incentives.
