⚙️Technical Specifications
⭐Product Advantages
Exceptional Productivity & Efficiency
The 9F-70 delivers an impressive productivity rate of 5-20 tons per hour, making it ideal for large-scale farming and industrial operations. Its powerful 191 kW diesel engine combined with the hammer-type rotor system ensures rapid and efficient pulverization of tough materials like alfalfa, wheat straw, and corn stover. This high efficiency significantly reduces operational time and labor costs while maintaining consistent output quality throughout extended working periods.
Versatile Material Processing
Designed to handle a comprehensive range of materials, the 9F-70 processes both dry hay and high-moisture silage without clogging or performance degradation. It efficiently crushes grass, straw, silage, corn stover, and various agricultural residues into uniformly chopped feed. This versatility extends beyond livestock feed to biomass fuel preparation, composting operations, and mushroom substrate production, making it a truly multi-functional investment.
Superior Feed Quality Control
Equipped with adjustable screen sizes, the machine provides precise control over particle lengths, typically ranging from 2-5 cm. This customization ensures the processed material is perfectly optimized for Total Mixed Ration (TMR) feeding systems, promoting better livestock digestion, reducing feed waste, and enhancing overall animal health and productivity. The consistent and uniform feed output supports the nutritional requirements of various livestock species.
Robust & Durable Construction
Built for heavy-duty applications, the 9F-70 features a reinforced welded housing and a stable structure designed to minimize vibrations during operation. The high-strength alloy hammers and wear-resistant grinding chamber components significantly extend the machine’s operational lifespan, reducing the frequency of maintenance interventions and associated downtime. This durable construction ensures reliable performance even under the most demanding agricultural conditions.
Efficient Cylindrical Feeding System
The innovative cylindrical feeding system accommodates entire round or square bales, allowing easy loading using grapple loaders. The rotating tub mechanism utilizes gravity and centrifugal force to ensure consistent material flow into the hammermill, preventing blockages and overloading while maintaining uninterrupted operation. This efficient design streamlines the feeding process, significantly reducing operator effort and processing time.
User-Friendly Operation & Maintenance
The 9F-70 is engineered with operator convenience in mind, featuring intuitive controls for adjusting screen sizes and monitoring operational parameters. The high-airflow design prevents clogging even when processing high-moisture materials, while easily accessible maintenance points simplify routine servicing. Clear documentation and straightforward procedures ensure that operators can maintain optimal performance with minimal training and downtime.
⚙️Working Principle
Powerful Hammer-Type Rotor System
The 9F-70 operates on a sophisticated hammer-type rotor system powered by a robust 191 kW diesel engine. This rotor is equipped with 64 high-strength alloy hammers that spin at a PTO shaft speed of 1800 r/min. As the hammers rotate at high velocity, they generate powerful kinetic forces that effectively crush and pulverize tough fibrous materials including grass, straw, corn stover, and alfalfa. This high-impact grinding mechanism ensures efficient processing of both dry and moist forage materials into smaller, uniform particles suitable for livestock consumption.
Cylindrical Feeding with Rotating Tub
The machine features an innovative cylindrical feeding system designed to accommodate entire round or square bales of forage material. Using grapple loaders, bales are loaded into the rotating tub, which employs gravity and centrifugal force to ensure consistent feeding into the hammermill. This design prevents material blockages and ensures smooth operation by distributing the forage evenly into the 1100 mm wide grinding chamber. The rotating tub mechanism eliminates the risk of overloading, maintaining stable performance throughout the processing cycle.
Adjustable Grinding Chamber & Screens
The grinding chamber is equipped with adjustable screens that provide precise control over the particle size of the output material. These screens allow operators to customize the forage length, typically ranging from 2-5 cm, depending on specific application requirements and livestock feeding protocols. The adjustable feature ensures that the processed materials meet the desired specifications for Total Mixed Ration (TMR) feeding, biomass fuel preparation, or composting applications. The wide grinding chamber enhances efficiency by accommodating large material volumes.
High-Airflow & Reinforced Housing Design
The machine employs an advanced high-airflow design that effectively prevents clogging, even when processing high-moisture materials like silage or wet straw. The reinforced welded housing absorbs vibrations during operation, ensuring stable and smooth performance while reducing wear and tear on critical components. This robust construction, combined with the efficient airflow mechanism, maintains consistent output quality and extends the operational lifespan of the machine, even under continuous heavy-duty agricultural and industrial conditions.
